pretix up to 2026.6.3/2026.7.2/2026.8.0 Session protection mechanism

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, was found in pretix up to 2026.6.3/2026.7.2/2026.8.0. This affects an unknown function of the component Session. The manipulation with an unknown input leads to a protection mechanism vulnerability. CWE is classifying the issue as CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The mechanism binding files generated during a shredding process to the authentication method is not working correctly and the same session token is used for all token-based API users. This is similar to an issue fixed in 2026.7.1 but was missed while creating the fix. Since the files are referred to by randomly generated UUIDs and only exist for a day, there is virtually no risk, but it renders the added protection mechanism useless. As part of the fix, we have also improved hardening of some other related code areas.

The advisory is shared at pretix.eu. This vulnerability is uniquely identified as CVE-2026-101272 since 09/28/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available.

Upgrading to version 2026.6.4, 2026.7.3 or 2026.8.1 eliminates this vulnerability.
