GHSA-g86p-hgx5-2pfh
CRITICALGHSA-g86p-hgx5-2pfh is a critical-severity (CVSS 9.8) Improper Authentication vulnerability in buildbot. O3 Security confirms whether GHSA-g86p-hgx5-2pfh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Improper Authentication in Buildbot
Blast Radius
buildbot🐍buildbotReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Buildbot before 1.8.2 and 2.x before 2.3.1 accepts a user-submitted authorization token from OAuth and uses it to authenticate a user. If an attacker has a token allowing them to read the user details of a victim, they can login as the victim.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | buildbot | all versions | 1.8.2 |
| 🐍PyPI | buildbot | ≥ 2.0.0&&< 2.3.1 | 2.3.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for buildbot. 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.
Fix
Update buildbot to 1.8.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g86p-hgx5-2pfh is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-g86p-hgx5-2pfh 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-g86p-hgx5-2pfh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-g86p-hgx5-2pfh in your dependencies?
O3 detects GHSA-g86p-hgx5-2pfh across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
