CVE-2022-36885
MEDIUMCVE-2022-36885 is a medium-severity (CVSS 5.3) CWE-203 vulnerability in com.coravy.hudson.plugins.github:github. O3 Security confirms whether CVE-2022-36885 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jenkins GitHub plugin uses weak webhook signature function
Real-World Exposure
com.coravy.hudson.plugins.github:githubReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Jenkins GitHub Plugin 1.34.4 and earlier uses a non-constant time comparison function when checking whether the provided and computed webhook signatures are equal, allowing attackers to use statistical methods to obtain a valid webhook signature.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | com.coravy.hudson.plugins.github:github | all versions | 1.34.5 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.coravy.hudson.plugins.github:github. 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 com.coravy.hudson.plugins.github:github to 1.34.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-36885 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-2022-36885 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-2022-36885. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
