Symlink Escape in Agent File Tools

Zed, a code editor, has a symlink escape vulnerability in versions prior to 0.225.9 in Agent file tools (`read_file`, `edit_file`). It allows reading and writing files **outside the project directory** when a project contains symbolic links pointing to external paths. This bypasses the intended workspace boundary and privacy protections (`file_scan_exclusions`, `private_files`), potentially leaking sensitive user data to the LLM. Version 0.225.9 fixes the issue.

Gainsight Assist plugin information disclosure

An attacker can extract user email addresses (PII) exposed in base64 encoding via the state parameter in the OAuth callback URL.

TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.

Improper Link Resolution in Dell Optimizer Enables Local Privilege Escalation

Dell Optimizer, versions prior to 6.3.1, contain an Improper Link Resolution Before File Access ('Link Following') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

BentoML has an Arbitrary File Write via Symlink Path Traversal in Tar Extraction

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.36, the safe_extract_tarfile() function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a malicious bento/model tar file containing a symlink pointing outside the extraction directory, followed by a regular file that writes through the symlink, achieving arbitrary file write on the host filesystem. This vulnerability is fixed in 1.4.36.

Gogs: Access tokens get exposed through URL params in API requests

Gogs is an open source self-hosted Git service. Prior to version 0.14.2, gogs api still accepts tokens in url params like token and access_token, which can leak through logs, browser history, and referrers. This issue has been patched in version 0.14.2.

node-tar: Hardlink Path Traversal via Drive-Relative Linkpath

node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This issue has been patched in version 7.5.10.

ImageMagick has a Path Policy TOCTOU symlink race bypass

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, domain="path" authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability

Free of memory not on the heap in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally.

Host Process for Windows Tasks Elevation of Privilege Vulnerability

Improper link resolution before file access ('link following') in Host Process for Windows Tasks allows an authorized attacker to elevate privileges locally.

Intego Personal Backup Task File Privilege Escalation

Intego Personal Backup, a macOS backup utility that allows users to create scheduled backups and bootable system clones, contains a local privilege escalation vulnerability. Backup task definitions are stored in a location writable by non-privileged users while being processed with elevated privileges. By crafting a malicious serialized task file, a local attacker can trigger arbitrary file writes to sensitive system locations, leading to privilege escalation to root.

passwd in Directory Services in Mac OS X 10.3.x before 10.3.9 and 10.4.x before 10.4.5 allows local users to overwrite arbitrary files via a symlink attack on the .pwtmp.[PID] temporary file.

Perl 5.004_04 and earlier follows symbolic links when running with the -e option, which allows local users to overwrite arbitrary files via a symlink attack on the /tmp/perl-eaXXXXX file.
