Mediawiki - DataTransfer Extension Cross-Site Request Forgery (CSRF) and Cross-site Scripting (XSS)

CVE-2025-23081GHSA-c3h5-h73c-29hq

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (mediawiki/data-transfer 1.42.2, 1.41.3, 1.39.11), 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.

# Patch Next advisory brief: CVE-2025-23081

Advisory: Mediawiki - DataTransfer Extension Cross-Site Request Forgery (CSRF) and Cross-site Scripting (XSS)
IDs: CVE-2025-23081, GHSA-c3h5-h73c-29hq
Record: https://patchnext.com/advisories/cve-2025-23081 (revision 1, source checked 26 Oct 2026, 14:29 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: mediawiki/data-transfer 1.42.2, 1.41.3, 1.39.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist mediawiki/data-transfer: affected >= 1.39.0, < 1.39.11; >= 1.41.0, < 1.41.3; >= 1.42.0, < 1.42.2; fixed in 1.39.11, 1.42.2, 1.41.3

## Suggested inspection (read-only)
- Packagist mediawiki/data-transfer: 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 mediawiki/data-transfer.
- 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-c3h5-h73c-29hq (GitHub-reviewed advisory GHSA-c3h5-h73c-29hq lists affected ranges: Packagist mediawiki/data-transfer >=1.39.0 =1.41.0 =1.42.0 <1.42.2)
