Description OSIDB Bzimport 2026-08-06 15:01:32 UTC 
A stored cross-site scripting issue in the HTML stats interface. Extensions that create dynamically named statistics could introduce attacker-controlled content into /stats?format=html. The fix properly escapes stat names during HTML generation.

CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N (7.4)

Embargoed until 2026-08-26 13:00 GMT per Envoy upstream disclosure. PSIRTSUPT-21132.
