miniOrange JWT Authentication for WP REST APIs plugin for WordPress before 4.8.0 contains an authentication method downgrade vulnerability that allows unauthenticated attackers to bypass administrator-configured authentication by supplying a specific GET parameter without any capability check or nonce verification. Attackers can force the plugin to use Basic HTTP authentication regardless of configured JWT or API token settings, then exploit distinguishable error codes and the absence of rate limiting to perform unthrottled username enumeration and credential guessing attacks.
AnalysisAI
Authentication downgrade in the miniOrange JWT Authentication for WP REST APIs WordPress plugin (versions before 4.8.0) lets unauthenticated remote attackers force the plugin to fall back to Basic HTTP authentication by supplying a crafted GET parameter, overriding whatever JWT or API token configuration the site administrator set. Because the vulnerable code path performs no capability check or nonce verification, and the plugin returns distinguishable error codes without rate limiting, attackers can chain the bypass into unthrottled username enumeration and credential guessing against WordPress REST endpoints. …
