Script execution via unneutralized uploaded filenames
Published Dec 4, 2024 · Updated Dec 25, 2024
Reflected XSS in Convert Forms before 4.4.8 allows remote authenticated users to execute script via a malicious uploaded filename. The file-upload response reflects attacker-controlled markup from a submitted filename into the victim browser without adequate neutralization. Exploitation requires low-privileged access, a crafted web page, and victim interaction; successful execution runs in the victim browser context.
