PT-2026-103622

Name of the Vulnerable Software and Affected Versions PyJWT versions 2.11.0 through 2.13.0 Description The PyJWT. merge options function can modify a mutable options mapping provided by the caller when verify signature is set to false. If an application reuses this modified mapping in subsequent...

EUVD-2026-45938

Network-AI before 5.13.4 contains an improper cryptographic signature verification vulnerability in APSAdapter where the default local verifier accepts any non-empty string as valid. Unauthenticated attackers can submit forged APS delegation payloads with arbitrary scopes to bypass signature...

CVE-2026-49852

joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption JOSE standards. Prior to 1.6.8, joserfc.jwt.decode accepts attacker-forged HMAC-signed tokens when the caller-supplied verification key is the empty string or None, because HMACAlgorithm.sign...

CVE-2026-16093

Keycloak provides a mechanism called Client Policies to enforce security requirements on clients, such as requiring them to use signed JWTs for authentication. A flaw was discovered where this enforcement can be bypassed. An attacker with valid client credentials can provide a fake, unsigned...

CVE-2023-22482

A flaw was found in ArgoCD. GitOps is vulnerable to an improper authorization bug where the API may accept invalid tokens. ID providers include an audience claim in signed tokens, which may be used to restrict which services can accept the token. ArgoCD doesn't properly validate the audience clai...

GHSA-64RH-R86Q-75FF Hard coded cryptographic key in Kiali

A hard-coded cryptographic key vulnerability in the default configuration file was found in Kiali, all versions prior to 1.15.1. A remote attacker could abuse this flaw by creating their own JWT signed tokens and bypass Kiali authentication mechanisms, possibly gaining privileges to view and alte...

JSON Web Token None Hashing Algorithm

JSON Web Tokens can be signed to protect against data tampering. By using an asymmetric or a symmetric signing algorithm, the application computes a signature of the token data which will be verified during token decoding to ensure its integrity. JSON Web Tokens can be configured by an applicatio...

Kiali Service Mesh Privilege Escalation

The vulnerability of the management console for the Istio Kiali service mesh is related to the use of a strictly encrypted encryption key. Exploiting this vulnerability allows an attacker to enhance their privileges by creating self-signed access tokens...
