PyJWT: Public-key JWK accepted as HMAC secret enables forged HS256 tokens when mixed families are allowed

!NOTE Exploitation requires a verifier configured with both symmetric and asymmetric algorithms in algorithms=… and a raw-JSON JWK as the key= argument, both contrary to documented usage, hence the High attack-complexity rating. Summary When the verifier is decoding JSON Web Tokens, while...

Use Of Hard-coded Cryptographic Key

github.com/dhax/go-base is vulnerable to Use of Hard-coded Cryptographic Key. The vulnerability is due to a hardcoded JWT signing secret "random" being used as both the default configuration and programmatic fallback, combined with an ineffective mitigation that only replaced the exact value...

CVE-2026-48558

SimpleHelp versions 5.5.15 and prior and 6.0 pre-release versions contain an authentication bypass vulnerability in the OIDC authentication flow. When OIDC authentication is configured, identity tokens submitted during login are accepted without verifying their cryptographic signature. In a...

CVE-2026-40496

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, attachment download tokens are generated using a weak and predictable formula: md5APPKEY + attachmentid + size. Since attachmentid is sequential and size can be brute-forced in a small range, an unauthenticate...

CVE-2026-40514

HAXCMS 安全漏洞

HAXCMS is an open-source content management system developed by HAX The Web. Versions of HAX CMS prior to Node.js 26.0.0 contained security vulnerabilities. These vulnerabilities stemmed from two encryption implementation errors in the hmacBase64 function. This could allow unauthenticated attacke...

CVE-2026-48522

A flaw was found in PyJWT, a JSON Web Token implementation in Python. The PyJWKClient component, prior to version 2.13.0, directly passes its Uniform Resource Identifier URI argument to urllib.request.urlopen. This allows a remote attacker, by influencing the application's jku URL ingestion path,...

CVE-2026-48523

A flaw was found in PyJWT, a Python library for handling JSON Web Tokens JWT. An attacker with control over a registered JSON Web Key JWK private key can bypass security checks by signing a token with a forbidden algorithm while claiming to use an allowed one. This allows the attacker to have the...

GHSA-3QG8-5G3R-79V5 praisonai-platform: JWT signing key defaults to hardcoded "dev-secret-change-me", allowing token forgery for any user when PLATFORM_ENV is unset

Summary Type: Insecure default cryptographic key. The JWT signing secret defaults to the hardcoded literal "dev-secret-change-me" when PLATFORMJWTSECRET is unset. A safety check exists but only fires when PLATFORMENV != "dev"; the default value of PLATFORMENV is "dev", so the check is silently...
