SECURITY-3588 / CVE-2025-5806
Gatling Plugin 136.vb_9009b_3d33a_e serves Gatling reports in a manner that
bypasses the `Content-Security-Policy` protection introduced in Jenkins
1.641 and 1.625.3.

This results in a cross-site scripting (XSS) vulnerability exploitable by
users able to change report content.

As of publication of this advisory, there is no fix.
