1.25.12→1.25.13Invoking failure to reject ASCII-only Punycode-encoded labels in golang.org/x/net/idna
CVE-2026-39821 / GO-2026-5026
More information
Details
The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error.
This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".

Enforce maximum recursion depth in encoding/asn1
CVE-2026-33818 / GO-2026-5972
More information
Details
Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures.

Add recursion depth guard during decode in encoding/xml
CVE-2026-56859 / GO-2026-6088
More information
Details
Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion.

Apply ReadHeaderTimeout when doing unencrypted HTTP/2 check in net/http
CVE-2026-56853 / GO-2026-6089
More information
Details
When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this.

Limit handshake messages we are willing to accept post-handshake in crypto/tls
CVE-2026-56862 / GO-2026-6090
More information
Details
Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely.

Fix Javascript regexp context tracking in html/template
CVE-2026-56858 / GO-2026-6091
More information
Details
Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS.

Avoid quadratic complexity in resolvePath in net/url
CVE-2026-56860 / GO-2026-6218
More information
Details
Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead.
Now, path resolution operates on a byte buffer using index-based backtracking for '..' segments, eliminating the quadratic time complexity and significantly reducing memory allocations.
