    CVE-2026-10099 (GCVE-0-2026-10099)

    Vulnerability from nvd – Published: 2026-05-29 15:58 – Updated: 2026-06-23 16:13

    Title
    XX-Net V5.16.6 WebSocket Frame Parsing Data Corruption via simple_http_server.py
    Summary
    XX-Net V5.16.6 contains a WebSocket frame parsing vulnerability in the WebSocket_receive_worker routine of simple_http_server.py that allows attackers to cause corrupted application data by sending unmasked WebSocket frames. The server unconditionally reads 4 bytes as a masking key regardless of whether the MASK bit is set in the frame header, causing the first 4 bytes of payload to be consumed as a mask key and the remaining payload to be incorrectly XOR-decoded, resulting in data corruption alongside missing RSV bit, opcode, and FIN fragmentation validations.
