CVE-2026-119764 is a medium-severity flaw (CVSS 6.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Mythic 3.2.16 through 3.4.0.61 contains a stored cross-site scripting vulnerability that allows attackers controlling target endpoint files to run JavaScript in the Mythic UI origin by planting HTML in .pdf-named files. When an operator downloads the file and clicks Preview Media, content-sniffed HTML from /direct/view renders same-origin, stealing localStorage JWTs for full GraphQL and REST access.
