GHSA-2cv5-qvq3-6276 is a high-severity (CVSS 7.6) CWE-116 vulnerability in nilsteampassnet/teampass. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-2cv5-qvq3-6276 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
TeamPass vulnerable to Improper Encoding or Escaping of Output
Real-World Exposure
nilsteampassnet/teampassReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
TeamPass prior to 3.0.10 is vulnerable to cross-site scripting filter bypass in folder names. This can lead to information disclosure.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | nilsteampassnet/teampass | all versions | 3.0.10 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nilsteampassnet/teampass. 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 nilsteampassnet/teampass to 3.0.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2cv5-qvq3-6276 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-2cv5-qvq3-6276 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-2cv5-qvq3-6276. 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-2cv5-qvq3-6276 in your dependencies?
O3 detects GHSA-2cv5-qvq3-6276 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
