What is CVE-2026-101272?

A flaw in Pretix's authentication mechanism exists where the session token generated during the shredding process is not functioning as intended. This leads to the same session token being applied to all token-based API users, compromising the intended security enhancements. While the affected files are uniquely identified by randomly generated UUIDs and are short-lived, the persistence of this issue diminishes the effectiveness of the protective measures put in place. Additionally, recent updates have strengthened related code areas to address potential vulnerabilities.
