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

OpenBao's namespaces provide multi-tenant separation. A tenant who leaks token accessors can have their token revoked or renewed by a privileged administrator in another tenant.

Patches

This was addressed in v2.5.3.

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. 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.

  2. Fix

    Update github.com/openbao/openbao to 0.0.0-20260420162526-f58111d2ca54 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p49j-v9wc-wg57 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 pinpoints whether GHSA-p49j-v9wc-wg57 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-p49j-v9wc-wg57. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
