Unauthenticated Path Traversal Vulnerability in WordPress
Problem
WordPress contains an unauthenticated path traversal vulnerability that allows attackers to achieve conditional remote code execution via user‑controlled template paths. The issue stems from locate_template() not adequately validating paths, enabling exploitation by ordinary users. Furthermore, WordPress lacks a robust file‑path abstraction, causing such vulnerabilities to recur frequently.
Pain points
- Lack of safe file‑path abstractions, leading to frequent security vulnerabilities such as path traversal
- Insufficient validation of user‑controlled template paths, resulting in unauthorized code execution risks
- Messy code documentation and undocumented methods in WordPress, increasing development and maintenance complexity
Questions to verify
- Is there interest in building or using a tool that can automatically detect and fix WordPress theme template path traversal vulnerabilities?
- Does the current WordPress ecosystem lack safe file‑path abstraction tools similar to this?
- When upgrading or migrating, are enterprise users more likely to seek alternative solutions to avoid such vulnerabilities?
Evidence
quote
Note that locate_template() does not prevent directory traversal attacks, so if you’re passing a user-provided template name to the function, be sure to verify that it’s from one of the three appropriate locations (active theme directory, parent theme directory, or /wp-includes/theme-compat/ directory).
fact
WordPress 7.1.2 has been released containing a fix for the vulnerability, and as a courtesy to users on older branches the fix has been backported to all branches back to 4.7
