EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

GHSA-gchq-9r68-6jwv plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 377,166 CVEs with a current EPSS score, this one falls in the 10–50% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description

Jenkins Credentials Plugin prior to 2.3.19, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.7.1, and 2.3.0.1 does not escape user-controlled information on a view it provides, resulting in a reflected cross-site scripting (XSS) vulnerability.

Jenkins Credentials Plugin 2.3.19, 2.3.15.1, 2.3.14.1, 2.3.13.1, 2.3.7.1, and 2.3.0.1 restricts the user-controlled information it provides to a safe subset.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:credentials, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:credentials to 2.3.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gchq-9r68-6jwv is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-gchq-9r68-6jwv can be triaged on real exposure rather than presence alone.

Tailored to GHSA-gchq-9r68-6jwv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
