CVE-2026-18682Public exploitNetwork attack vector

Browser script execution via crafted file upload

Published Aug 3, 2026 · Updated Aug 3, 2026

Stored cross-site scripting in OpenAkita 1.27.0 through 1.27.12 allows remote attackers to execute script in a user's browser. The /api/upload File Upload API stores a crafted File argument without neutralizing script content before later display. Exploitation requires a crafted upload and user interaction with the stored content; the resulting script can alter data within that browser session.
