CVE-2026-50160

Hoppscotch is an API development ecosystem. In self-hosted deployments of hoppscotch-backend from version 2026.4.1 and earlier, the unauthenticated POST /v1/onboarding/config endpoint is vulnerable to mass assignment. The global NestJS ValidationPipe is configured without whitelist: true, so extr...

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...

Security Bulletin: Multiple security vulnerabilities are addressed with IBM Process Mining 2.2.0

Summary Multiple vulnerabilities were addressed in IBM Process Mining 2.2.0 Vulnerability Details CVEID:CVE-2026-22021 DESCRIPTION: Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Java SE. Successful attacks of this vulnerability can...

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...

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

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...

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-2026-57997 Strapi users-permissions - JWT Algorithm Confusion via Missing Algorithm Configuration

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...

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...

PYSEC-2026-269 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...

PYSEC-2026-390 LiteLLM: Authentication bypass via OIDC userinfo cache key collision

Impact When 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. A...

PYSEC-2026-285 AstrBot is vulnerable to RCE with hard-coded JWT signing keys

Summary AstrBot 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...

PYSEC-2026-252 acryl-datahub missing JWT signature check

Missing JWT signature check GHSL-2022-078 The StatelessTokenService of the DataHub metadata service GMS does not verify the signature of JWT tokens. This allows an attacker to connect to DataHub instances as any user if Metadata Service authentication is enabled. This vulnerability occurs because...

GHSA-WPHV-VFRH-23Q5 joserfc: b64=false RFC7797 JWS payloads bypass JWSRegistry payload-size limits during deserialization

RFC7797 b64=false JWS payloads bypass JWSRegistry payload-size limits during deserialization Summary Testing revealed that joserfc accepts oversized RFC7797 b64=false JWS payloads without applying JWSRegistry.maxpayloadlength. The normal JWS compact and flattened JSON paths reject payloads above...

EUVD-2026-39567

A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to...
