• CVE-2020-2288: 0.95% estimated exploitation activity in the next 30 days; percentile 61.36 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Jenkins Audit Trail Plugin uses regular expressions to match requested URLs whose dispatch should be logged. In Jenkins Audit Trail Plugin 3.6 and earlier, the default regular expression pattern could be bypassed in many cases by adding a suffix to the URL that would be ignored during request handling. Jenkins Audit Trail Plugin 3.7 changes the default regular expression pattern so that it allows for arbitrary suffixes. It automatically will replace previous default patterns with the new, more complete default pattern. Additionally, an administrative monitor is shown if a user-specified pattern is found to be bypassable through crafted URLs and form validation was improved to recognize patterns that would not match requests with arbitrary suffixes.

# Patch Next advisory brief: CVE-2020-2288

Advisory: Incorrect default pattern in Jenkins Audit Trail Plugin
IDs: CVE-2020-2288, GHSA-7v9p-34r2-q668
Record: https://patchnext.com/advisories/cve-2020-2288 (revision 1, source checked 26 Oct 2026, 16:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.jenkins-ci.plugins:audit-trail 3.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:audit-trail: affected < 3.7; fixed in 3.7

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:audit-trail: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:audit-trail.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-7v9p-34r2-q668 (GitHub-reviewed advisory GHSA-7v9p-34r2-q668 lists affected ranges: Maven org.jenkins-ci.plugins:audit-trail >=0 <3.7)
