The Link Whisper Free WordPress plugin before 0.9.1 has a publicly accessible REST endpoint that allows unauthenticated settings updates.
AnalysisAI
Unauthenticated attackers can modify plugin settings via a publicly accessible REST endpoint in Link Whisper Free WordPress plugin before version 0.9.1, enabling information disclosure and unauthorized configuration changes. The vulnerability has publicly available exploit code and affects all versions prior to 0.9.1. Although the CVSS score is 6.5 (medium), the EPSS score of 0.02% indicates very low real-world exploitation probability despite public POC availability.
Technical ContextAI
Link Whisper Free exposes a REST API endpoint that lacks proper authentication checks, violating the principle of secure-by-default API design in WordPress plugin development. The endpoint accepts settings updates (PR:N in CVSS vector indicates no privileges required) without validating user authentication or authorization tokens. This is a common WordPress plugin vulnerability pattern where developers expose administrative functionality through REST routes without applying WordPress's nonce or capability checks. The affected component is the plugin's settings management system, exposed via WordPress's REST API infrastructure.
RemediationAI
Upgrade Link Whisper Free WordPress plugin to version 0.9.1 or later immediately. This is the vendor-released patch that addresses the unauthenticated REST endpoint vulnerability. Site administrators should verify the plugin version in WordPress plugin management interface and update via the automatic update mechanism or manual upload.
