Real-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

When OpenBao's initial namespace deletion fails, subsequent retries fail to properly remove all data before marking the namespace as deleted. This can affect any outstanding leases as well as potentially leaving unrelated storage entries around.

Patches

This will be patched in OpenBao v2.5.3.

Workarounds

Users may manually remove mounts prior to deleting the namespace.

Audit logs may be used to identify repeated deletion attempts against the same namespace; sys/raw can be used to see what leases were not correctly deleted.

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/openbao/openbao, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/openbao/openbao to 0.0.0-20260420173541-6d2e0506e2b4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vv66-6rp4-wr4f 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vv66-6rp4-wr4f can be triaged on real exposure rather than presence alone.

Tailored to GHSA-vv66-6rp4-wr4f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
