CVE-2026-0812Network attack vector

Administrator-level stored XSS via unescaped settings

Published Jan 14, 2026 · Updated Jan 14, 2026

Stored XSS in LinkedIn SC 1.1.9 and earlier allows remote authenticated users with administrator access to inject scripts through plugin settings. The settings handler stores the linkedin_sc_date_format, linkedin_sc_api_key, and linkedin_sc_secret_key values without sanitizing them, and the settings page emits them without output escaping. Administrator-level WordPress access is required; injected scripts execute in a user's browser when the affected page is viewed.
