Name of the Vulnerable Software and Affected Versions REVA versions prior to 2.40.3 REVA versions prior to 2.42.3

Description A flaw exists in the GRPC authorization middleware of the "Reva" component of OpenCloud. This allows a malicious user to bypass scope verification of a public link. By exploiting this through the "archiver" service, an attacker can create an archive (zip or tar-file) containing all resources accessible to the creator of the public link. The issue is not exploitable via WebDAV requests.

Recommendations Update to REVA version 2.40.3 or later. Update to REVA version 2.42.3 or later.
