CWE-59
AllowedImproper Link Resolution Before File Access ('Link Following')
Abstraction: Base · Status: Draft
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
2031 vulnerabilities reference this CWE, most recent first.
GHSA-7XMQ-G46G-F8PV
Vulnerability from github – Published: 2026-03-02 21:55 – Updated: 2026-03-02 21:55Summary
Sandbox media handling had a time-of-check/time-of-use gap: media paths could be validated first and read later through a separate path. A symlink retarget between those steps could cause reads outside sandboxRoot.
Impact
Affected versions could permit host file reads outside the intended sandbox root in media attachment/image flows.
Fix
Media reads now use consolidated root-scoped, boundary-safe read paths at use time, removing check/use drift across call sites.

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.
