CVE-2026-11943Public exploitNetwork attack vector

Stored script execution via raw timeline description

Published Jun 22, 2026 · Updated Jun 22, 2026

Stored cross-site scripting in Akaunting 3.1.21 allows remote authenticated users to execute script in other users' browsers. The profile update path stores an unfiltered name, timeline components interpolate it into translated document descriptions, and the accordion header renders the description as raw Blade output. The attacker must update a profile and create or cancel an invoice or bill; viewing that document then executes the stored HTML or JavaScript in another authenticated user's session.
