Whole-script approval in Jenkins Script Security Plugin vulnerable to SHA-1 collisions
EPSS Exploitation Probability
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
CVE-2022-45379 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 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

Description
Script Security Plugin 1189.vb_a_b_7c8fd5fde and earlier stores whole-script approvals as the SHA-1 hash of the approved script. SHA-1 no longer meets the security standards for producing a cryptographically secure message digest.
Script Security Plugin 1190.v65867a_a_47126 uses SHA-512 for new whole-script approvals. Previously approved scripts will have their SHA-1 based whole-script approval replaced with a corresponding SHA-512 whole-script approval when the script is next used.
Whole-script approval only stores the SHA-1 or SHA-512 hash, so it is not possible to migrate all previously approved scripts automatically on startup.
Administrators concerned about SHA-1 collision attacks on the whole-script approval feature are able to revoke all previous (SHA-1) script approvals on the In-Process Script Approval page.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:script-security, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:script-security to 1190.v65867a_a_47126 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-45379 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-45379 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-45379. 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.
OpenShift 3.11 is already in the ELS support model phase. The Jenkins components are out of scope of the ELS support; hence OpenShift 3.11 Jenkins component is marked in this CVE as out of support scope.
