Detailsinfo

A vulnerability, which was classified as critical, has been found in PeerTube up to 7.1.0. Affected by this issue is an unknown code of the component ZIP File Handler. The manipulation with an unknown input leads to a data amplification vulnerability. Using CWE to declare the problem leads to CWE-409. The product does not handle or incorrectly handles a compressed input with a very high compression ratio that produces a large output. Impacted is availability. CVE summarizes:

This vulnerability allows any authenticated user to cause the server to consume very large amounts of disk space when extracting a Zip Bomb. If user import is enabled (which is the default setting), any registered user can upload an archive for importing. The code uses the yauzl library for reading the archive. The yauzl library does not contain any mechanism to detect or prevent extraction of a Zip Bomb https://en.wikipedia.org/wiki/Zip_bomb . Therefore, when using the User Import functionality with a Zip Bomb, PeerTube will try extracting the archive which will cause a disk space resource exhaustion.

The advisory is available at github.com. This vulnerability is handled as CVE-2025-32949 since 04/14/2025. The exploitation is known to be easy. The attack may be launched remotely. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.
