python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens
A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

PT-2026-54774
Name of the Vulnerable Software and Affected Versions Centrifugo affected versions not specified Description Centrifugo contains a cross-tenant JWT authentication bypass when using dynamic JWKS JSON Web Key Set endpoints. The issue occurs because the JWKS cache and singleflight lookup are keyed...
EUVD-2026-40234
Strapi users-permissions plugin fails to restrict JWT algorithms when plugin::users-permissions.jwt.algorithm is not explicitly configured, allowing acceptance of HS384 and HS512 tokens alongside HS256. Attackers possessing the jwtSecret can mint tokens with non-standard HMAC variants to bypass...
jwt-auth Plugin Unauthorized Access
The vulnerability of the jwt-auth plugin for the Apache APISIX cloud API gateway involves bypassing authentication through spoofing. Exploiting this vulnerability allows a malicious actor to circumvent security restrictions and gain unauthorized access to protected information...
Use of a Broken or Risky Cryptographic Algorithm
Overview @strapi/plugin-users-permissions is a headless CMS Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm due to improper restriction of accepted JWT algorithms in the plugin::users-permissions.jwt.algorithm configuration. An attacker can...
CVE-2026-57997

CVE-2026-57997
The CVE concerns the Strapi users-permissions plugin where JWT algorithm restrictions are not enforced if plugin::users-permissions.jwt.algorithm is not explicitly configured. This allows the server to accept HS384 and HS512 tokens alongside HS256. An attacker who possesses the jwtSecret can mint...

CVE-2026-12616
The /v1/upload/sbom endpoint extracts the iss claim from the attacker-supplied JWT with signature verification disabled, then interpolates that string into three log statements before any validation gate. Because the configured log format "%asctimes - %names - %levelnames - %messages" renders...

praisonai-platform: JWT signing key defaults to hardcoded "dev-secret-change-me", allowing token forgery for any user when PLATFORM_ENV is unset
SummaryType: 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...
LiteLLM: Authentication bypass via OIDC userinfo cache key collision
ImpactWhen JWT authentication is enabled enablejwtauth: true, the OIDC userinfo cache uses token:20 as the cache key. JWT headers produced by the same signing algorithm generate identical first 20 characters.This configuration option is not enabled by default. Most instances are not affected.An...

Apache Airflow: JWT token still valid after logout
When user logged out, the JWT token the user had authtenticated with was not invalidated, which could lead to reuse of that token in case it was intercepted. In Airflow 3.2 we implemented the mechanism that implements token invalidation at logout. Users who are concerned about the logout scenario...

Authlib JWS JWK Header Injection: Signature Verification Bypass
Description SummaryA JWK Header Injection vulnerability in authlib's JWS implementation allows an unauthenticatedattacker to forge arbitrary JWT tokens that pass signature verification. When key=None is passedto any JWS deserialization function, the library extracts and uses the cryptographic key...
AstrBot is vulnerable to RCE with hard-coded JWT signing keys
SummaryAstrBot uses a hard-coded JWT signing key, allowing attackers to execute arbitrary commands by installing a malicious plugin. Details AstrBot uses a hard-coded JWT signing key, which allows attackers to bypass the authentication mechanism. Once bypassed, the attacker can install a Python...
