Where this sits among everything scored
Real-World Exposure
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.

zitadelzitadelDetection & 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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
