GHSA-v6fx-752r-ccp2
HIGHGHSA-v6fx-752r-ccp2 is a high-severity (CVSS 8.1) Cross-Site Request Forgery (CSRF) vulnerability in pghero. O3 Security confirms whether GHSA-v6fx-752r-ccp2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
PgHero gem allows CSRF
Blast Radius
pgheroReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
The PgHero gem through 2.6.0 for Ruby allows CSRF. PgHero normally uses the protect_from_forgery method from Rails to prevent CSRF. However, this defaults to :null_session, which has no effect on non-session based authentication methods. Thus the ruby gem is vulnerable with non-session based authentication methods like basic authentication.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pghero. 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 pghero to 2.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v6fx-752r-ccp2 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-v6fx-752r-ccp2 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-v6fx-752r-ccp2. 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-v6fx-752r-ccp2 in your dependencies?
O3 detects GHSA-v6fx-752r-ccp2 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
