CVE-2026-33691 Apr 02, 15:03 HIGH PATCH This Week

OWASP Core Rule Set (CRS) versions prior to 3.3.9 and 4.25.0 allow bypass of file upload restrictions through whitespace-padded filenames, enabling upload of dangerous executable file extensions (.php, .phar, .jsp, .jspx) that should be blocked. Remote attackers can exploit this vulnerability to upload malicious files with high confidence due to the simple nature of the bypass technique (inserting spaces before the file extension), potentially leading to remote code execution depending on web application firewall configuration and application behavior.
