# Patch Next advisory brief: CVE-2022-41965

Advisory: Authenticated OpenRedirect Vulnerability
IDs: CVE-2022-41965, GHSA-r3qr-vwvg-43f7
Record: https://patchnext.com/advisories/cve-2022-41965 (revision 1, source checked 26 Oct 2026, 16:01 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.opencastproject:opencast-common 12.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.opencastproject:opencast-common: affected < 12.5; fixed in 12.5

## Suggested inspection (read-only)
- Maven org.opencastproject:opencast-common: 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.opencastproject:opencast-common.
- 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
