CVE-2026-116067
Paisa before 0.7.8 contains a path traversal vulnerability in the GetFile, GetSheet, DeleteBackups, and DeleteSheetBackups handlers that lets unauthenticated attackers read files and delete backups through ../ sequences in file names.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Paisa before 0.7.8 contains a path traversal vulnerability in the GetFile, GetSheet, DeleteBackups, and DeleteSheetBackups handlers that lets unauthenticated attackers read files and delete backups through ../ sequences in file names. Attackers can send crafted names to the editor file and delete_backups endpoints to read any server-readable file and remove backup files outside the journal or sheets directory.
