CVE-2026-53524
A flaw was found in WeeChat. An authenticated user of the relay module's WebSocket functionality can send a small compressed frame that, when decompressed, expands to a significantly larger size. This "decompression bomb" can exhaust all available server memory, leading to a Denial of Service DoS...
