CVE-2026-113724 virtualenv: Deletion recovery can change a symlink target's mode

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the safedelete deletion error handler responds to a failed removal by reading mode bits with os.lstatpath and applying owner-write permission with os.chmodpath, ..., which follows a symlink. A planted link...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack via the onerror handler in src/virtualenv/util/path/sync.py, which previously called os.chmod on a path without first checking whether it is a symbolic link. On Windows, when a read-only file cannot be deleted during a tr...

CVE-2026-113724

The virtualenv tool, used for creating isolated Python environments, is vulnerable to a symlink-following issue in versions prior to 21.14.9 . The safe_delete() deletion error handler uses os.lstat(path) to read mode bits and os.chmod(path, ...) to apply owner-write permissions. Because these ope...

CVE-2026-88016: Improper Link Resolution Before File Access

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, when backend/local runs with --links, a source .rclonelink object can plant a symlink in the destination and later directory metadata is applied through that path...

PT-2026-75956

Summary When writing an object with metadata, the local backend applies the source-supplied mode, uid, and gid verbatim: it parses mode as an octal integer and passes it straight into os.Chmodo.path, os.FileModeumode, and passes uid/gid straight into os.Chown. The value is never masked to...
