Description
The mechanism binding API-uploaded files to the uploader's authentication method is not working correctly and the same session token is used for all token-based API users. Since API-uploaded files are refered to by randomly generated UUIDs and only exist for a day, there is virtually no risk, but it renders the added protection mechanism useless.

AI Analysis

Impact

A mechanism designed to bind API‑uploaded files to the uploader’s session token does not function correctly, causing all token‑based API users to share the same session token. Because uploaded files are referenced by random UUIDs and automatically deleted after one day, the direct security risk is low; however, the intended protection mechanism is rendered ineffective.

Affected Systems

The vulnerability affects the pretix event‑ticketing platform. Versions prior to the 2026‑7‑01 release are impacted; no specific version range is listed in the available data.

Risk and Exploitability

The CVSS score is 2.3, indicating a low severity issue. The EPSS score is not available and the vulnerability is not listed in CISA KEV. The likely attack vector involves internal or external API access using legitimate API tokens, but the short lifespan of files and the absence of additional identified privileges mean that exploitation is unlikely to pose significant danger.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the pretix 2026‑7‑01 patch or a later revision that resolves the session validation issue.
  • Revoke and regenerate all API tokens until the patch is applied, ensuring no temporary exposures remain.
  • Audit API‑uploaded file access after remediation to confirm that session tokens are properly validated and that the protection mechanism functions as intended.
