Source description

As published by the source; long descriptions are shortened.

Convert To Pipeline Plugin 1.0 and earlier does not require POST requests for the HTTP endpoint converting a Freestyle project to Pipeline, resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to create a Pipeline based on a Freestyle project. Combined with SECURITY-2966/CVE-2023-28677, this can result in the execution of unsandboxed Pipeline scripts.

# Patch Next advisory brief: CVE-2023-28676

Advisory: Jenkins Convert To Pipeline Plugin vulnerable to cross-site request forgery
IDs: CVE-2023-28676, GHSA-48g9-h7g5-8pw2
Record: https://patchnext.com/advisories/cve-2023-28676 (revision 1, source checked 26 Oct 2026, 16:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jenkins-ci.plugins:convert-to-pipeline: affected <= 1.0

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.jenkins-ci.plugins:convert-to-pipeline.
- 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-48g9-h7g5-8pw2 (GitHub-reviewed advisory GHSA-48g9-h7g5-8pw2 lists affected ranges: Maven org.jenkins-ci.plugins:convert-to-pipeline >=0 <=1.0)

Commands are suggestions: review each one before running it.
