Install With npm: npm install --global jwt-cracker Usage From command line: jwt-cracker Where: token : the full HS256 JWT token string to cra...

Signature Verification Bypass

F21 JWT is vulnerable to signature verification bypasses. A malicious user can pass a malicious token to the application to bypass token signature verification...

Timing Attacks

Malcolm Fell jwt is vulnerable to timing attacks. The library does not compare hashes in constant time, which allows malicious users to use the timing of the request to progressively identify a valid hash...

CVE-2017-8034

The Cloud Controller and Router in Cloud Foundry CAPI-release capi versions prior to v1.32.0, Routing-release versions prior to v0.159.0, CF-release versions prior to v267 do not validate the issuer on JSON Web Tokens JWTs from UAA. With certain multi-zone UAA configurations, zone administrators...

Code injection

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by...
