EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-f3gh-529w-v32x plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
ZITADEL's Admin API contains Insecure Direct Object Reference (IDOR) vulnerabilities that allow authenticated users, without specific IAM roles, to modify sensitive settings. While several endpoints are affected, the most critical vulnerability lies in the ability to manipulate LDAP configurations. Customers who do not utilize LDAP for authentication are not at risk from the most severe aspects of this vulnerability. However, we still strongly recommend upgrading to the patched version to address all identified issues.
Description
ZITADEL's Admin API, intended for managing ZITADEL instances, contains 12 HTTP endpoints that are unexpectedly accessible to authenticated ZITADEL users who are not ZITADEL managers. The most critical vulnerable endpoints relate to LDAP configuration:
- /idps/ldap
- /idps/ldap/{id}
By accessing these endpoints, unauthorized users could:
- Modify ZITADEL's instance LDAP settings, redirecting all LDAP login attempts to a malicious server, effectively taking over user accounts.
- Expose the original LDAP server's password, potentially compromising all user accounts.
Additional Vulnerable Endpoints
The following endpoints are also affected by IDOR vulnerabilities, potentially allowing unauthorized modification of instance settings such as languages, labels, and templates:
- /idps/templates/_search
- /idps/templates/{id}
- /policies/label/_activate
- /policies/label/logo
- /policies/label/logo_dark
- /policies/label/icon
- /policies/label/icon_dark
- /policies/label/font
- /text/message/passwordless_registration/{language}
- /text/login/{language}
Impact
The impact of this vulnerability varies depending on whether a ZITADEL instance utilizes LDAP for authentication:
- LDAP Users: Successful exploitation could lead to complete takeover of user accounts and exposure of the LDAP server's password.
- Non-LDAP Users: While the most severe risks are related to LDAP, exploitation of the additional vulnerable endpoints could still allow unauthorized modification of instance settings, impacting all organizations.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/zitadel/zitadel/v2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/zitadel/zitadel/v2 to 2.63.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f3gh-529w-v32x is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-f3gh-529w-v32x can be triaged on real exposure rather than presence alone.
Tailored to GHSA-f3gh-529w-v32x. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-f3gh-529w-v32x in your dependencies?
O3 Security finds GHSA-f3gh-529w-v32x across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
