Description OSIDB Bzimport 2026-07-29 09:01:34 UTC 
Apache Traffic Server mis-parses ports in URLs and userinfo, allowing port-based access-control bypass.

This issue affects Apache Traffic Server: from 8.0.0 through 8.1.9, from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3.

Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fix the issue.
