Hi,
The following vulnerability was published for libre.
CVE-2026-50161[0]:
| libre is a generic library for real-time communications with
| asynchronous input and output support. Prior to 4.8.1, the
| websock_decode() function in src/websock/websock.c contains an
| integer overflow when validating a masked WebSocket frame that uses
| the 64-bit extended length encoding. The expression 4 + hdr->len can
| wrap when hdr->len is close to UINT64_MAX, causing the
| mbuf_get_left() bounds check to pass. The subsequent XOR unmasking
| loop then writes beyond the heap buffer. Applications using
| websock_accept() or websock_accept_proto() to implement a WebSocket
| server are affected, and exploitation can cause attacker-controlled
| heap corruption or denial of service after the HTTP WebSocket
| upgrade handshake. This issue is fixed in version 4.8.1.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
