CVE-2023-0162Network attack vector

Stored XSS via unescaped content-type settings

Published Jan 10, 2023 · Updated Apr 8, 2026

Stored XSS in WPChill CPO Companion 1.0.4 and earlier allows remote authenticated users to run scripts through content-type settings. The content-type settings handlers store attacker-supplied parameter values and render them without adequate sanitization or output escaping. Administrator-level permissions are required, and the payload executes when a user opens an injected page, exposing that user's browser session.
