GHSA-q98f-2x4p-prjr
MEDIUMGHSA-q98f-2x4p-prjr is a medium-severity (CVSS 6.5) Information Exposure vulnerability in github.com/pomerium/pomerium. O3 Security confirms whether GHSA-q98f-2x4p-prjr is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Exposure of debug and metrics endpoints in Pomerium
Blast Radius
github.com/pomerium/pomeriumReal-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
In distributed service mode, Pomerium's Authenticate service exposes pprof debug and prometheus metrics handlers to untrusted traffic. This can leak potentially sensitive environmental information or lead to limited denial of service conditions.
Patches
v0.17.1
Workarounds
Block access to /debug and /metrics paths on the authenticate service. This can be done with any L7 proxy, including Pomerium's own proxy service.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/pomerium/pomerium. 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/pomerium/pomerium to 0.17.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q98f-2x4p-prjr 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-q98f-2x4p-prjr 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-q98f-2x4p-prjr. 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-q98f-2x4p-prjr in your dependencies?
O3 detects GHSA-q98f-2x4p-prjr across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
