CVE-2022-29168Network attack vector

Account takeover via unescaped mention rendering

Published Jun 25, 2022 · Updated Apr 23, 2025

Stored cross-site scripting in Wire Web App before 2022-05-04-production.0 allows attackers to execute JavaScript when a recipient views a message. The @mention renderer fails to escape attacker-controlled HTML, causing the browser to parse injected markup and JavaScript in the victim context. Exploitation requires the recipient to view the crafted message and grants control of the victim's Wire account; connected desktop clients inherit the exposure.
