MEDIUM 6.5EPSS 0.94%

Does this matter?

Lower severity and a low EPSS score (0.94%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.
