AI analysisSummaries by Vani AI
A relative path traversal flaw lets an authenticated user who holds the Restore Operator role and also controls the contents of a backed-up NAS share write attacker-controlled files to an arbitrary path on the backup server. Triggering it requires that privileged role and control of the share; no user interaction is required. Integrity of the backup server is the impact. Affected products and versions are not named.
What to do: No fixed version is listed for CVE-2026-108141. Limit who holds Restore Operator and who can change backed-up NAS share contents.
