JWT Signature Verification Companion
GratisJWT / Auth Tooling
Warning icon on a jjwt Jwts.parser()...parse(token) call chain: jjwt's own parse method accepts a JWT whose signature is empty or doesn't match, even when a signing key has been configured on the parser. This is a documented real vulnerability class: CodeQL ships a dedicated "Missing JWT signature check" query for exactly this pattern, and jjwt's own issue tracker confirms it. The fix is easy
La brecha que resuelve
Jwts.parser().setSigningKey(key).build().parse(token) compiles fine, runs fine, and looks like it verifies the token — a signing key was even configured. It doesn't. An attacker can hand this code an unsigned or mismatched-signature JWT and it gets accepted, exactly the "algorithm confusion" / signature-bypass class of bug this plugin exists to catch before it ships.
