CVE-2024-52554
HIGHScript security bypass vulnerability in Jenkins Shared Library Version Override Plugin
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.

Description
Jenkins Shared Library Version Override Plugin 17.v786074c9fce7 and earlier declares folder-scoped library overrides as trusted, so that they're not executed in the Script Security sandbox, allowing attackers with Item/Configure permission on a folder to configure a folder-scoped library override that runs without sandbox protection.
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 io.jenkins.plugins:shared-library-version-override. 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 io.jenkins.plugins:shared-library-version-override to 19.v3a or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-52554 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 CVE-2024-52554 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 CVE-2024-52554. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-52554 in your dependencies?
O3 detects CVE-2024-52554 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
