golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

CVE-2026-80213 - Hostname validation bypass

An application that checks a hostname against an allow list or an SSRF filter and then resolves it can be made to look up a domain other than the one it checked. The string that passes validation and the name that reaches the network are not the same, so the connection can end up at a host the...

CVE-2026-55526

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, spidertools.hostisblocked does not resolve ordinary hostnames before scrapepage fetches them. A hostname such as 127.0.0.1.nip.io passes validation and resolves to loopback, permitting internal HTTP access. The fix uses...
