0 CVE-2026-86861 is a time-of-check to time-of-use (TOCTOU) race condition vulnerability in pgAdmin 4's File Manager save_file endpoint affecting versions before 9.18. The vulnerability allows a symbolic link substitution attack between the access permission check and the file write operation, potentially enabling an attacker with filesystem access to overwrite arbitrary files outside the user's storage directory. The issue was fixed by enforcing kernel-level protection (O_NOFOLLOW) on the file write operation and restricting file permissions to mode 0600.
