CVE-2024-39683
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedZITADEL is an open-source identity infrastructure tool. ZITADEL provides users the ability to list all user sessions of the current user agent (browser). Starting in version 2.53.0 and prior to versions 2.53.8, 2.54.5, and 2.55.1, 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. Versions 2.55.1, 2.54.5, and 2.53.8 contain a fix for the issue. There is no workaround since a patch is already available.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.53.82.54.5
2.55.1 (or 2.54.5 if staying on 2.54.x, or 2.53.8 if staying on 2.53.x)
- Identify the currently running Zitadel version by checking the instance or container logs
- Review Zitadel release notes for versions 2.53.8, 2.54.5, and 2.55.1 to identify any migration requirements
- Plan the upgrade path: if on 2.53.x upgrade to 2.53.8; if on 2.54.x upgrade to 2.54.5; if on 2.55.0 upgrade to 2.55.1
- Backup the Zitadel database and configuration before proceeding with the upgrade
- Follow the official Zitadel upgrade documentation for your deployment method (Kubernetes, Docker, or binary)
- After upgrade, verify the version number matches the intended fixed release
- Test that user session listing now correctly filters sessions based on user ownership
