CVE-2026-57817 Apache CXF: The authorization code hash (c_hash) is not enforced for the hybrid OIDC flow

The OpenID Connect Core 1.0 specification mandates that the RP MUST validate the chash parameter when operating in the Hybrid Flow. If an Apache CXF RP is integrated with a non-compliant or misconfigured Identity Provider IdP that omits the chash, the RP becomes vulnerable to Authorization Code...

CVE-2026-57817

A flaw in Apache CXF allows for Authorization Code Substitution/Injection attacks during the OpenID Connect Hybrid Flow. The vulnerability occurs because the cxf-rt-rs-security-sso-oidc library (and the broader cxf component) fails to enforce the validation of the c_hash parameter, as required by...

BLAKE3 v1.8.6

BLAKE3 BLAKE3 is a cryptographic hash function that is: Much faster than MD5, SHA-1, SHA-2, SHA-3, and BLAKE2. Secure , unlike MD5 and SHA-1. And secure against length extension, unlike SHA-2. Highly parallelizable across any number of threads and SIMD lanes, because it's a Merkle tree on the...

Canonicalization Failures As a Recurring Vulnerability Class: Representation Divergence in Cryptographic Systems and Its Avoidance

Cryptographic systems operate on bytes but mean semantic objects. The translation between the two is rarely unique. Where this uniqueness is not enforced, an attack surface opens up as soon as a hash, a signature, replay protection, or consensus identity depends on the representation. The same...

IBM Langflow OSS Code Execution Vulnerability

IBM Langflow OSS is the open-source version of Langflow that IBM officially integrates and promotes. IBM Langflow OSS has a code execution vulnerability. This vulnerability stems from the use of truncated SHA-256 hashes for code verification by the custom component validation mechanism. The hashi...

Nuxt: Unauthenticated CPU exhaustion parsing and hashing the Nuxt island endpoint body before hash validation

Impact The internal island renderer endpoint /nuxtisland/... decodes and hashes attacker-controlled request input before it validates the URL-resident hash. An unauthenticated POST /nuxtisland/.json with a large JSON body for example 4.6 MB / 150k keys is fully read, destr-parsed, and run through...
