Summary

Omnispace Agora Project before 26.10.0 contains a broken access control flaw in the MobileFileDownload route (CWE-639). The route accepts an md5 hash of a file name as its only authorization token, so an unauthenticated remote attacker can download arbitrary files by computing that token. Attackers who can guess or determine file names can retrieve protected files without authorization, leading to unauthorized information disclosure.

Description from the CNA

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability in the MobileFileDownload route that allows unauthenticated attackers to download arbitrary files by computing an md5(filename) token instead of passing a proper authorization check. Attackers can guess or determine file names to generate the corresponding md5 token and retrieve protected files without authorization, leading to unauthorized information disclosure.
