    CVE-2026-118689 (GCVE-0-2026-118689)

    Vulnerability from nvd – Published: 2026-10-28 21:11 – Updated: 2026-11-03 13:39
    VLAI
    Title
    OvenMediaEngine through 0.21.0 OVT Relay DoS via Oversized payload_length
    Summary
    OvenMediaEngine through 0.21.0 contains a denial of service vulnerability in OvtPacket::LoadHeader() that allows unauthenticated attackers to stall connections by sending payload_length values above 32750. Attackers can send crafted OVT packets to the OVT listener to hold connections open indefinitely and accumulate buffered memory, disrupting origin-to-edge stream relay.
