Summary

This security advisory fixes a vulnerability in eZ Publish Legacy, and we recommend that you install it as soon as possible if you are using Legacy via the LegacyBridge.

Installations where all modules are disabled may be vulnerable to XSS injection in the module name. This is a rare configuration, but we still recommend installing the update, which adds the necessary input washing.

To install, use Composer to update to one of the "Resolving versions" mentioned above, or apply this patch manually: https://github.com/ezsystems/ezpublish-legacy/commit/4697bff700e8cf95d5847ea19dad3479a77b02d9

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
