CVE-2026-114101

6.3 medium exploit ×2 SSVC exploitation: poc Published

Coraza before 3.8.1 extracts multipart upload filenames with Go's mime.ParseMediaType, which silently ignores RFC 5987 filename* parameters whose charset is not utf-8 or us-ascii. Unauthenticated attackers can send a decoy filename with filename*=iso-8859-1''shell.php, or filename* alone, so FILES-based rules never see the real name, letting dangerous uploads reach backends that honor filename*.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.

Public exploits 2

Each line links to the index that lists it, never to exploit code. Exploit-DB's "verified" and a Metasploit rank of good or better count as verified; a PoC-in-GitHub entry is a repository's claim.
