JWT Auth – WordPress JSON Web Token Authentication Security & Risk Analysis

The jwt-auth plugin, version 3.0.2, exhibits a generally good security posture with several strengths, including 100% of SQL queries using prepared statements and a single nonce check and capability check present. The absence of dangerous functions, file operations, and external HTTP requests, coupled with no critical or high severity taint flows, indicates careful coding practices in these areas. However, a critical vulnerability in its history, specifically an 'Access of Resource Using Incompatible Type' type, despite being patched, warrants attention and suggests that the plugin may be susceptible to complex vulnerabilities. The relatively low number of total entry points (2) with none noted as unprotected is also a positive indicator.
