How CVE-2025-3419 Works
The Eventin plugin (<= 4.0.26) for WordPress contains an unauthenticated arbitrary file read vulnerability in the `proxy_image()` function. Attackers exploit insufficient input validation by manipulating the `url` parameter to fetch server files (e.g., /etc/passwd, wp-config.php). The function fails to restrict access to local file paths, allowing directory traversal (e.g., ../../). This exposes sensitive data like database credentials, API keys, and system files. The flaw stems from missing sanitization checks before file operations.
