Description Oleg Sushchenko 2026-10-27 19:28:45 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's experimental wasm plugin has a use-after-free in its transaction-close handler and forwards unvalidated guest-supplied metric IDs to the internal stats API.



This issue affects Apache Traffic Server: from 10.0.0 through 10.1.4, 10.2.0.



Users are recommended to upgrade to version 10.1.5 or 10.2.1, which fix the issue.
