Oct 16, 2026Lightweight Cookie Notice – Cookie Banner for Cookie Consent: Sensitive Information ExposureCVE-2026-12272 · affects up to 1.19 · reported by WordfenceMedium 5.3
The Lightweight Cookie Notice – Cookie Banner for Cookie Consent plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.19 This is due to the W3TC_DYNAMIC_SECURITY constant being hardcoded to a publicly known value.
