CVE-2026-9712

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.
