What is CVE-2026-41241?

The pretalx conference planning tool prior to version 2026.1.0 is susceptible to an HTML injection vulnerability. This issue arises when the organiser search functionality displays submission titles, speaker names, and user details using innerHTML string interpolation. Any registered user can manipulate these fields to insert malicious HTML or JavaScript code. If an organiser performs a search that matches these malicious records, it can lead to the execution of unauthorized scripts within the organisor's browser. To mitigate this risk, it is crucial to update to version 2026.1.0 or later.
