Description OSIDB Bzimport 2026-10-21 18:42:25 UTC 
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.
