CVE-2023-26771Public exploitNetwork attack vector

Victim-context JavaScript execution via unrestricted profile uploads

Published Oct 4, 2024 · Updated Oct 4, 2024

Stored XSS in Taskcafe 0.3.2 allows remote authenticated users to execute JavaScript in a victim browser via an uploaded profile image. The profile-image upload endpoint accepts HTML or SVG content with embedded JavaScript, stores it in the public uploads directory, and serves it without restricting the file type. Execution requires a member to upload the file and a victim to open its URL; the script can read account data available to the victim session and perform actions with that session.
