Towards Secure and Trustworthy DAOs for Cross-Chain Governance

Cross-chain DAOs face unique security challenges that go beyond traditional single-chain vulnerabilities. This paper identifies and categorizes four critical attack vectors in cross-chain DAO governance: bribery attacks, token control exploits, human-computer interaction deceptions, and protocol...

CVE-2026-33754 Wazuh: Unauthenticated cluster packet length leads to uncontrolled memory allocation (remote DoS)

Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.9.0 and above, prior to 4.14.5, a remote attacker can trigger memory exhaustion in the cluster protocol parser by sending a crafted message header with an arbitrarily large payload length...

CVE-2026-33754

Wazuh 3.9.0+ is affected by an unauthenticated DoS in the cluster protocol parser caused by a crafted header with an arbitrarily large payload length. The vulnerability arises because the length is trusted before authentication/decryption and used to allocate memory, leading to memory exhaustion ...

CVE-2026-54340 h2o has HTTP/2 state amplification

h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 9265bdd, there is an HTTP/2 state amplification issue that combines HPACK decompression amplification with Slowloris-style stream stalling. Amplified decoded header state can be retained by stalled HTTP/2 streams,...

CVE-2026-54340 affects the h2o HTTP server (HTTP/2) and describes an HTTP/2 state amplification issue where HPACK decompression amplification combines with Slowloris-style stream stalling. Amplified decoded header state can be retained by stalled HTTP/2 streams; depending on configuration, additi...

CVE-2026-44435

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit 937d0e9, an assertion failure is raised when the total number of valid handshake messages received over a CRYPTO stream of a single packet number space exceeds 32KB, causing a...

CVE-2026-44436

Quicly (QUIC implementation used with H2O) is vulnerable to a Denial of Service due to connection state corruption caused by a 255-byte Connection ID handling in the decoder, while QUIC version 1 requires a 20-byte CID buffer. The library lacked enforcement for 20-byte CIDs, allowing mismatched I...
