Description Guilherme de Almeida Suckevicz 2026-07-29 19:58:00 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Apache Traffic Server allows request smuggling if chunked messages are malformed.

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.

Comment 1 Jered Floyd 2026-08-13 02:13:41 UTC

Fixed in 9.2.15/10.1.4 but apparently Bodhi has a search limit of 20 bugs so it didn't auto-close.
