How to Fix CVE-2026-45701

To remediate this vulnerability, upgrade all affected Sulu dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

sulu/sulu fixed: 3.0.6 
Upgrade sulu/sulu to 3.0.6
sulu/sulu fixed: 2.6.23 
Upgrade sulu/sulu to 2.6.23
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for sulu/sulu

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-45701, inspect your project dependencies for Sulu:

inspect dependencies for sulu/sulu

Analyze the terminal output to locate any version of Sulu in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.
