1.25.8→1.25.11TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix
BIT-golang-2026-32282 / CVE-2026-32282 / GO-2026-4864
More information
Details
On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root.
The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.

JsBraceDepth Context Tracking Bugs (XSS) in html/template
BIT-golang-2026-32289 / CVE-2026-32289 / GO-2026-4865
More information
Details
Context was not properly tracked across template branches for JS template literals, leading to possibly incorrect escaping of content when branches were used. Additionally template actions within JS template literals did not properly track the brace depth, leading to incorrect escaping being applied.
These issues could cause actions within JS template literals to be incorrectly or improperly escaped, leading to XSS vulnerabilities.

Unbounded allocation for old GNU sparse in archive/tar
BIT-golang-2026-32288 / CVE-2026-32288 / GO-2026-4869
More information
Details
tar.Reader can allocate an unbounded amount of memory when reading a maliciously-crafted archive containing a large number of sparse regions encoded in the "old GNU sparse map" format.

Unauthenticated TLS 1.3 KeyUpdate record can cause persistent connection retention and DoS in crypto/tls
BIT-golang-2026-32283 / CVE-2026-32283 / GO-2026-4870
More information
Details
If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service.
This only affects TLS 1.3.

Inefficient policy validation in crypto/x509
BIT-golang-2026-32281 / CVE-2026-32281 / GO-2026-4946
More information
Details
Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service.
This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.

Unexpected work during chain building in crypto/x509
BIT-golang-2026-32280 / CVE-2026-32280 / GO-2026-4947
More information
Details
During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls.

Infinite loop in HTTP/2 transport when given bad SETTINGS_MAX_FRAME_SIZE in net/http/internal/http2 in golang.org/x/net
BIT-golang-2026-33814 / CVE-2026-33814 / GO-2026-4918
More information
Details
When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0.

ReverseProxy forwards queries with more than urlmaxqueryparams parameters in net/http/httputil
BIT-golang-2026-39825 / CVE-2026-39825 / GO-2026-4976
More information
Details
ReverseProxy can forward queries containing parameters not visible to Rewrite functions.
When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not take ParseQuery's limit on the total number of query parameters (controlled by GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a query parameter that is not visible to the Rewrite function.
For example, the query "a1=x&a2=x&...&a10000=x&hidden=y" can forward the parameter "hidden=y" while hiding it from the proxy's Rewrite function.

Escaper bypass leads to XSS in html/template
BIT-golang-2026-39826 / CVE-2026-39826 / GO-2026-4980
More information
Details
If a trusted template author were to write a <script> tag containing an empty 'type' attribute or a 'type' attribute with an ASCII whitespace, the execution of the template would incorrectly escape any data passed into the <script> block.

Bypass of meta content URL escaping causes XSS in html/template
BIT-golang-2026-39823 / CVE-2026-39823 / GO-2026-4982
More information
Details
CVE-2026-27142 fixed a vulnerability in which URLs were not correctly escaped inside of a tag's attribute. If the URL content were to insert ASCII whitespaces around the '=' rune inside of the attribute, the escaper would fail to similarly escape it, leading to XSS.

Inefficient candidate hostname parsing in crypto/x509
BIT-golang-2026-27145 / CVE-2026-27145 / GO-2026-5037
More information
Details
(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries. This caused strings.Split(host, ".") to execute repeatedly on the same input hostname.
With a large DNS SAN list, verification costs scaled quadratically based on the number of SAN entries multiplied by the hostname's label count. Because x509.Verify validates hostnames before building the certificate chain, this overhead occurred even for untrusted certificates.
