CVE-2026-95115Network attack vectorHinoki check available

Denial of service via JSON parser overflow

Published Oct 13, 2026 · Updated Oct 13, 2026

Buffer overflow in libwebsockets at revision 106d542c allows remote attackers to interrupt service via the LEJP JSON parser. The supplied record does not identify the overflowing buffer or incorrect bounds operation, and retrieved upstream material does not establish the specific faulty code path. Remote reachability depends on a consuming application passing attacker-controlled input to LEJP; the record does not distinguish a crash from a hang or establish the required privileges.
