CVE-2023-6806Network attack vector

Stored XSS via unsanitized Job Settings fields

Published Feb 20, 2024 · Updated Apr 8, 2026

Stored XSS in Squirrly Limited Starbox 3.4.8 and earlier allows remote authenticated users to execute scripts through Job Settings fields. The user-profile save path stores Job Settings values without sufficient input sanitization, and author-box rendering emits them without adequate output escaping. Subscriber-level access is sufficient; the injected script runs in the browser of any visitor who opens a page containing the affected author's box.
