GHSA-cvw9-c57h-3397
MEDIUMZITADEL Vulnerable to Session Information Leakage
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.
Blast Radius
github.com/zitadel/zitadel🐹github.com/zitadel/zitadel🐹github.com/zitadel/zitadelReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
ZITADEL provides users the ability to list all user sessions of the current user agent (browser) by API and in the Console UI.
Due to a missing check, user sessions without that information (e.g. when created though the session service) were incorrectly listed exposing potentially other user's sessions.
Note that the Login UI was never affected and there was no possibility to take over such a session.
Patches
2.x versions are fixed on >= 2.55.1 2.54.x versions are fixed on >= 2.54.5 2.53.x versions are fixed on >= 2.53.8
ZITADEL recommends upgrading to the latest versions available in due course.
Workarounds
There is no workaround since a patch is already available.

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. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/zitadel/zitadel to 2.53.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cvw9-c57h-3397 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 pinpoints whether GHSA-cvw9-c57h-3397 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-cvw9-c57h-3397. 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-cvw9-c57h-3397 in your dependencies?
O3 detects GHSA-cvw9-c57h-3397 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
