Description

lakeFS is an open-source tool that transforms object storage into a Git-like repository. Existing lakeFS users who have issued credentials to users who have been deleted are affected by this vulnerability. When creating a new user with the same username as a deleted user, that user will inherit all of the previous user's credentials. This issue has been addressed in release version 1.33.0 and all users are advised to upgrade. The only known workaround for those who cannot upgrade is to not reuse usernames.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/treeverse/lakefs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/treeverse/lakefs to 1.33.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-43784 is resolved across your whole dependency graph.

  3. 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.
