CVE-2026-101126
Client-supplied filenames and display names are trusted directly, introducing potential cross-session claiming, metadata tampering, and path traversal risks (e.g., via getFilePath())
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
