CVE-2025-14388 - PhastPress <= 3.7 - unauthenticated arbitrary file read via null byte injection

CVE ID : CVE-2025-14388 Published : Dec. 23, 2025, 9:20 a.m. | 1 hour, 2 minutes ago Description : The PhastPress plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Read via null byte injection in all versions up to, and including, 3.7. This is due to a discrepancy between the extension validation in `getExtensionForURL()` which operates on URL-decoded paths, and `appendNormalized()` which strips everything after a null byte before constructing the filesystem path. This makes it possible for unauthenticated attackers to read arbitrary files from the webroot, including wp-config.php, by appending a double URL-encoded null byte (%2500) followed by an allowed extension (.txt) to the file path.
