- CVE-2026-33818: encoding/asn1 - enforce a maximum recursion depth in parseField and parseSequenceOf, so a deeply nested crafted DER payload can no longer exhaust the stack while unmarshalling - CVE-2026-56862: crypto/tls - only treat application data, and handshake records seen before the handshake completes, as state-advancing, so a peer can no longer spam post-handshake KeyUpdate messages to force unbounded key derivation - CVE-2026-56860: net/url - resolve reference paths on a byte buffer with index-based backtracking instead of rebuilding a string on every ".." segment, removing the quadratic time and allocation cost - CVE-2026-56859: encoding/xml - track unmarshal depth on the decoder stack instead of a local counter that DecodeElement reset, so a custom UnmarshalXML implementation can no longer bypass the depth limit and exhaust the stack - CVE-2026-56858: html/template - keep the JavaScript regexp/division context up to date across brace transitions, so pathological input can no longer close an unescaped '/' early and inject arbitrary content
