FileGator < 7.14.2 - Privilege Escalation

FileGator accepts arbitrary Unix permission values via the '/chmoditems' API endpoint and passes the value directly to PHP's native 'chmod' function through 'octdec' conversion, with no validation. This allows an authenticated user with 'chmod' permission to upgrade their privileges to root. id:...

rsync: Fix of 2 CVEs

CVE-2026-29518: re-implement the "use chroot = no" confinement after the centos7els fix: every path operation proves its parent directory beneath the pinned module root through /proc/self/fd and runs on it with the at calls. In-module symlinks, directories the daemon uid may search but not read,...

Filelock: UnixFileLock Truncates And Chmods Any Regular File Another User Renames Or Hard-links Onto The Lock Path

"UnixFileLock", the backend of "FileLock" and "AsyncFileLock" on Unix, empties whatever regular file it finds at the lock path once it holds the "flock" a kernel lock on an open file. With an explicit "mode" it also chmods that file sets its permission bits, whether or not this acquire created it...

Virtualenv: Deletion Recovery Can Change A Symlink Target's Mode

Summary The deletion error handler obtains permission bits with lstat but applies them through chmod, which follows symlinks. On an eligible unlink failure this can change permissions outside the destination. Anthropic's OSS Scanner reported this as "ANT-2026-UK90QC27" in "virtualenv-20261015-005...

CVE-2026-112909 filelock: UnixFileLock truncates and chmods any regular file another user renames or hard-links onto the lock path

filelock is a platform-independent file lock for Python. Prior to 4.2.1, UnixFileLock can truncate a regular file renamed onto the lock path when another local user has actual rename permission, or hard-linked there under a permissive hard-link policy; when an explicit mode is requested, affected...
