CWE-59
AllowedImproper Link Resolution Before File Access ('Link Following')
Abstraction: Base · Status: Draft

1999 vulnerabilities reference this CWE, most recent first.
GHSA-FCFM-93GV-WH6F
Vulnerability from github – Published: 2026-05-26 13:30 – Updated: 2026-05-27 21:31Archive::Tar versions before 3.08 for Perl extract hardlinks to attacker controlled paths outside the extraction directory.
_make_special_file() passes the tar header's linkname to link() without validating it against absolute paths or .. segments, creating a hardlink that shares the victim file's inode.
A subsequent write through the extracted name modifies the victim file, and the post-extraction chmod, chown, and utime block in _extract_file() (guarded only against symlinks via -l) applies the tar header's mode, owner, and timestamps to the shared inode during extraction alone.

GHSA-FFR4-MRHV-VFR2
Vulnerability from github – Published: 2026-03-21 03:31 – Updated: 2026-03-27 20:18Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-36h3-7c54-j27r. This link is maintained to preserve external references.
Original Description
OpenClaw versions prior to 2026.2.25 contain a symlink traversal vulnerability in browser trace and download output path handling that allows local attackers to escape the managed temp root directory. An attacker with local access can create symlinks to route file writes outside the intended temp directory, enabling arbitrary file overwrite on the affected system.

GHSA-FGVX-58P6-GJWC
Vulnerability from github – Published: 2026-03-02 22:40 – Updated: 2026-03-20 21:36Impact
The gateway agents.files.get and agents.files.set methods allowed symlink traversal for allowlisted workspace files. A symlinked allowlisted file (for example AGENTS.md) could resolve outside the agent workspace and be read/written by the gateway process.
This could enable arbitrary host file read/write within the gateway process permissions, and chained impact up to code execution depending on which files are overwritten.

>= 2026.2.25
Remediation
agents.files now resolves real workspace paths, enforces containment for resolved targets, rejects out-of-workspace symlink targets, and keeps in-workspace symlink targets supported. The patch also adds gateway regression tests for blocked escapes and valid in-workspace symlink behavior.

Mitigation MIT-48.1
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
