curl: libcurl omits IPv6 zoneid from host identity and leaks credentials/cookies across scoped link-local realms

Summary: libcurl omits the IPv6 zoneid component from multiple security-sensitive host identity decisions even though the connection layer still routes by zoneid. As a result, two distinct scoped/link-local destinations such as fe80::X%zoneA and fe80::X%zoneB are treated as the same host by...

Improper Access Control

Hono is vulnerable to Improper Access Control. The vulnerability is due to inconsistent cookie parsing between browsers and the parse function, where differently formatted cookie names may be normalized to the same key, allowing attacker-controlled cookies to override legitimate ones and bypass...
