CVE-2026-120635 | CVSS: N/A
CGI versions before 5.00 for Perl allow form fields to be smuggled past proxies and WAFs via multipart parsing that differs from the RFCs.
The multipart/form-data parser matches the boundary anywhere rather than at the start of a line, uses the boundary without its leading — for some client-supplied User-Agent values, finds the Content-Disposition name and filename inside the quoted values of other parameters, and corrupts parts when the boundary nears the 4096-byte read size.
