CVE-2026-9712

Technical Description

When creating an export through the pretix API, API clients are

returned an UUID value for their export job (a long, random string like

35742818-c375-4d15-839f-d49aecce94d6). Using this UUID, the API client

can then request the actual file for download. The same kind of UUID is

used in other places in pretix when temporary files are generated for

internal use or download.

One remaining API endpoint, however, wrongfully did not verify if the

UUID used for download actually belongs to a file that is supposed to

be downloadable and belongs to the correct user. In reality, this is

hard to exploit because an attacker would need to have access to a valid

UUID for the file they desire which is unlikely to happen without a

separate security problem giving them access to logs etc.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
