Non-constant time nonce comparison in Jenkins Microsoft Entra ID (previously Azure AD) Plugin

CVE-2023-41935GHSA-hj7p-h74j-6gxj

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.jenkins-ci.plugins:azure-ad 397.v907382dd9b, 378.vd6e2874a), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Jenkins Azure AD Plugin 396.v86ce29279947 and earlier, except 378.380.v545b1154b3fb, uses a non-constant time comparison function when checking whether the provided and expected CSRF protection nonce are equal, potentially allowing attackers to use statistical methods to obtain a valid nonce.

# Patch Next advisory brief: CVE-2023-41935

Advisory: Non-constant time nonce comparison in Jenkins Microsoft Entra ID (previously Azure AD) Plugin
IDs: CVE-2023-41935, GHSA-hj7p-h74j-6gxj
Record: https://patchnext.com/advisories/cve-2023-41935 (revision 1, source checked 26 Oct 2026, 16:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
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:azure-ad 397.v907382dd9b, 378.vd6e2874a. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:azure-ad: affected >= 378.380.v545b, <= 396.v86ce29279947; < 378.vd6e2874a; fixed in 378.vd6e2874a, 397.v907382dd9b

## Suggested inspection (read-only)
- Maven org.jenkins-ci.plugins:azure-ad: 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:azure-ad.
- 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-hj7p-h74j-6gxj (GitHub-reviewed advisory GHSA-hj7p-h74j-6gxj lists affected ranges: Maven org.jenkins-ci.plugins:azure-ad >=378.380.v545b =0 <378.vd6e2874a)
