CVE-2026-102271: Improper Verification of Cryptographic Signature

PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...

Name of the Vulnerable Software and Affected Versions PyJWT versions prior to 2.14.0 Description The PyJWKClient component fails to revalidate redirect destinations against the JWKS trust boundary. When a trusted JWKS endpoint returns a redirect influenced by an attacker, the client follows it an...

CVE-2026-102272: Improper Verification of Cryptographic Signature

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.preparekey in jwt/algorithms.py is affected because raw-JWK detector does not normalize accepted Unicode byte-order marks before checking for JSON. This occurs when a public JWK is prefixed with ...

Cheap to Hypothesize, Costly to Verify: The Defense Surface of Agentic Vulnerability Discovery

Autonomous LLM agents turn vulnerability discovery into a repository-scale search: they generate many vulnerability hypotheses but can verify only a subset under a finite budget. We show that autonomous vulnerability discovery exhibits a hypothesis-verification asymmetry, where verifying a...

DnsResolveContext Component Bypass Security Restrictions

The vulnerability of the DnsResolveContext component in the framework for developing network applications, servers, and Netty protocol clients is related to insufficient verification of data authenticity. Exploiting this vulnerability can allow an attacker to bypass security restrictions remotely...

Authlib library contains a signature‑verification bypass vulnerability

Overview Authlib versions up to and including 1.7.2 contain a signature‑verification bypass in the JSON Web Signature JWS general JSON serialization handling. The JsonWebSignature.deserializejson function accepts a JWS object with an empty "signatures" array and treats the payload as successfully...

CVE-2026-101049

The Heym application (versions before 0.0.53 ) is vulnerable to a Slack Webhook Signature Verification Bypass . The root cause is a failure to verify signatures when trigger nodes lack credential IDs or contain empty signing secrets. This allows remote unauthenticated attackers to send forged Sla...

CVE-2026-101049 Heym before 0.0.53 Slack Webhook Signature Verification Bypass

Heym before 0.0.53 fails to verify Slack request signatures when trigger nodes lack credential IDs or have empty signing secrets. Remote unauthenticated attackers can send forged Slack events to known webhook URLs to trigger workflows with the owner's credentials...

CVE-2026-89134 Subject CN name-constraint check bypassed when non-DNS SAN present

A certificate with no dNSName SAN but another SAN type present e.g. registeredID or iPAddress bypassed the Subject CN dNSName name-constraint check. The CN-as-DNS fallback was gated on cert-subjectCN != NULL && cert-altNames == NULL && !cert-isCA instead of "no dNSName SAN", so an out-of-scope CN...

CVE-2026-100665

A flaw was found in Netty. During certificate validation for Quick UDP Internet Connections QUIC, standard trust managers fail to perform endpoint identification to confirm the server's identity. A remote attacker positioned on the network path can exploit this flaw by presenting a valid...
