CVE-2026-44434 Quicly is vulnerable to stateless reset injection

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit dccf5d4, Quicly was vulnerable to stateless reset injection through lack of packet entry validation. The QUIC protocol is designed to withstand packet injection attacks, once the...

CVE-2026-44434

Quicly (QUIC protocol implementation used with H2O HTTP server) was vulnerable to stateless reset injection before commit dccf5d4 due to lack of packet entry validation, allowing an on-path attacker to reset QUIC connections by exploiting zero-initialized secret-pattern slots. The issue has been ...

CVE-2026-44433

CVE-2026-44433 concerns the Quicly QUIC implementation (used with H2O HTTP server). Before commit 8b178e6, an adversarial peer could send a STREAM frame with a single byte at the largest permitted offset to obtain additional flow control credit, potentially causing a denial of service. If the app...

CVE-2026-55173 AVideo incomplete fix for CVE-2026-33482: sanitizeFFmpegCommand still allows a single '&' (background operator), giving OS command execution at the same execAsync sh -c sink

WWBN AVideo is an open source video platform. Versions 29.0 and below remain vulnerable to OS command injection because the fix for CVE-2026-33482 was incomplete and still does not neutralize a single & the shell background operator. CVE-2026-33482 reported that sanitizeFFmpegCommand...

CVE-2026-15422 SCTP needs to better-check INIT ACK chunk parameters

The illumos SCTP inbound path performs association lookup for INIT ACK chunks without adequately validating the address parameters carried in the chunk. Since this lookup runs during packet classification i.e. before SCTP integrity checks or IPsec policy are applied a remote, unauthenticated...
