CVE-2026-41185 ServiceAccount token disclosure via Azure IPAM CNI plugin logs

When Calico is configured with the Azure IPAM plugin, the Calico CNI binary mutates the incoming CNI configuration to attach subnet information before delegating to the IPAM plugin. After mutating, the Azure IPAM helper logs the entire unmarshaled configuration map stdinData at INFO level to...

CVE-2026-41184

In Calico, the install-cni init container logs the rendered CNI configuration to standard output. When the configuration template uses the SERVICEACCOUNTTOKEN placeholder Canal/Flannel-Calico deployments, the installer substitutes the live Kubernetes ServiceAccount bearer token before logging,...

CVE-2026-6720

When calicoctl is invoked with --log-level=info or --log-level=debug, the client prints the full contents of its loaded connection-configuration struct to stderr in a single log line. The struct embeds every credential calicoctl uses to talk to the cluster — inline kubeconfig with bearer token,...

CVE-2026-47673

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.21, the jwt and jwk middlewares do not verify that the Authorization header value uses theBearer scheme.

CVE-2026-47673

CVE-2026-47673 concerns the Hono web framework. Before version 4.12.21, the jwt and jwk middlewares did not validate that the Authorization header used the Bearer scheme. Any two-part header value—regardless of the scheme name in the first position—proceeds to JWT verification. As a result, a req...

CVE-2026-48525

PyJWT is a JSON Web Token implementation in Python. From 2.8.0 to 2.12.1, when verifying detached JWS tokens using the unencoded-payload option "b64": false, RFC 7797, PyJWT performs Base64URL decoding of the compact-serialization payload segment before enforcing the detached-payload rules. For...

CVE-2026-48525 PyJWT: Unauthenticated DoS via unbounded Base64URL decoding of unused payload segment in b64=false detached JWS

CVE-2026-48523

PyJWT is a JSON Web Token implementation in Python. From 2.9.0 to 2.12.1, there is a verifier-side algorithm allow-list bypass when jwt.decode or jwt.decodecomplete are called with a PyJWK key. The token header alg is checked against the caller-supplied algorithms allow-list, but signature...
