CVE-2026-46611

Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances XML-RPC server glances -s, implemented in glances/server.py does not validate the HTTP Host header, leaving it vulnerable to DNS rebinding attacks. An attacker can exploit DNS rebinding to exfiltrate the...

CVE-2026-56123

CVE-2026-56123 affects socat versions 1.8.0.0 through 1.8.1.1. A signed-char sign-extension bug in the DOMAINNAME reply parser during SOCKS5 handshake allows a negative bytes_to_read value to be implicitly converted to size_t, causing an unbounded heap write into a 262-byte reply buffer. This res...
