CVE-2025-55182 Scanner is a high-performance tool for detecting vulnerable Next.js Server Action endpoints. It uses multi-threaded scanning, confidence-based detection, and multiple response indicators to identify potential Remote Code Execution RCE vulnerabilities. Features - High-speed concurre...

PyJWT.decode() reintroduces options-dict mutation, enabling silent claim-verification bypass on dict reuse

SummaryPyJWT.decode/decodecomplete mutates a caller-supplied options dict in place whenever verifysignature is falsy, adding verifyexp/verifynbf/verifyiat/verifyaud/verifyiss/verifysub/verifyjti keys directly onto that object. If application code reuses the same options dict across calls a config...

PyJWT: PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation

SummaryA service that verifies HS256 tokens using an empty oct JWK through PyJWK, including a PyJWK obtained from PyJWKSet, can therefore accept attacker-generated tokens as authenticated.PyJWT 2.13.0 rejects an empty HMAC key when it is supplied through the raw str/bytes key path, but accepts th...

PyJWT: Asymmetric-PEM detection bypass: whitespace/line-ending-mutated public keys skip the HS/asymmetric confusion guard

Prerequisites both conditions must hold; both are deployment properties, not attacker-controlled at request time:- The jwt.decode allow-list mixes an HMAC algorithm with an asymmetric one, e.g. algorithms="ES256", "HS256" the RFC 8725 footgun the guard exists to backstop.- The verification key is...

PyJWT: Non-canonical signature segments enable raw-token revocation bypass

SummaryPyJWT 2.13.0 accepts compact JWS signature segments containing characters thatare not in the Base64URL alphabet. Appending !!!! to a valid signature doesnot change the decoded signature bytes or authenticated claims, but it changesthe serialized token and its SHA-256 hash. An application...

social-auth-core: VK App backend accepts unsigned callback data when auth_key is missing

ImpactThe vk-app backend accepted VK application callback data without verifying the callback signature when the authkey parameter was omitted.Applications using this backend could treat unsigned attacker-controlled data as a verified VK identity. An attacker could choose callback fields such as...

Nautobot: Authorization bypass in approval workflow REST API allows self-approval and unauthorized activation of scheduled jobs

ImpactThis is an authorization bypass that escalates into unauthorized server-side job execution.1. Primary impact - self-approval: The approver checks approver-group membership, change permission on the object under review, one-response-per-user are enforced only in the approve/deny actions on...

Autobahn Python permessage-deflate bypasses maxMessagePayloadSize after inflation

SummaryAutobahn Python enforces maxMessagePayloadSize against the compressed WebSocket frame length before permessage-deflate inflation, then delivers the inflated message to application callbacks without a second size check.
