Summary
Jenkins GitHub plugin uses weak webhook signature function
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. GitHub Plugin 1.34.5 uses a constant-time comparison when validating the webhook signature.
Impact
CVE-2022-36885 has a CVSS score of 3.1 (Low). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.34.5); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2022-36885? CVE-2022-36885 is a low-severity security vulnerability in com.coravy.hudson.plugins.github:github (maven), affecting versions <= 1.34.4. It is fixed in 1.34.5.
- How severe is CVE-2022-36885? CVE-2022-36885 has a CVSS score of 3.1 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of com.coravy.hudson.plugins.github:github are affected by CVE-2022-36885? com.coravy.hudson.plugins.github:github (maven) versions <= 1.34.4 is affected.
- Is there a fix for CVE-2022-36885? Yes. CVE-2022-36885 is fixed in 1.34.5. Upgrade to this version or later.
- Is CVE-2022-36885 exploitable, and should I be worried? Whether CVE-2022-36885 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2022-36885 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2022-36885? Upgrade
com.coravy.hudson.plugins.github:githubto 1.34.5 or later.
