Description
Impact
A full technical disclosure and open-source patch will be published after the embargo period, ending on June 30th, to allow all users to upgrade.
Teleport security engineers identified a critical security vulnerability that could allow remote authentication bypass of Teleport.
Teleport Cloud Infrastructure and CI/CD build, test, and release infrastructure aren’t affected.
For the full mitigation, upgrade both Proxy and Teleport agents. It is strongly recommend updating clients to the released patch versions as a precaution.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gravitational/teleport. 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 github.com/gravitational/teleport to 17.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8cqv-pj7f-pwpc 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-8cqv-pj7f-pwpc 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-8cqv-pj7f-pwpc. 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-8cqv-pj7f-pwpc in your dependencies?
O3 detects GHSA-8cqv-pj7f-pwpc across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
