php: php: Access control bypass via partial IPv6 address comparison

A flaw was found in PHP. The access control check for Internet Protocol version 6 IPv6 addresses in the FastCGI implementation compares only the first 12 bytes of a 16-byte address instead of the complete address. An attacker on an adjacent network with an address sharing the first 96 bits with a...

CVE-2026-71855

A flaw was found in Suricata. This flaw allows a remote attacker to cause an IPv4 and IPv6 flow to be treated as identical due to a hash collision. This occurs when their raw address words, ports, protocol, VLAN, recursion level, live device, and hash bucket align, without proper comparison of th...

CVE-2026-57222

A flaw was found in Suricata. This vulnerability allows a remote attacker to cause an incorrect detection state by sending specially crafted IPv4 and IPv6 address pairs. The flaw occurs because the system's IPPair hash does not properly compare the IP address family, leading to the reuse of state...

lightrag-hku: SSRF via IPv6-transition address bypass (NAT64, IPv4-compatible, 6to4) of the native-markdown image-download guard

Summary LightRAG's native markdown parser downloads external images referenced by an uploaded markdown or textpack document. The only SSRF guard, validatedaddresses in lightrag/parser/markdown/parser.py, resolves the image host and rejects it when the resolved IP is not isglobal. That check is...
