Title
Unexpected work during chain building in crypto/x509
Summary
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.

Title
Inefficient policy validation in crypto/x509
Summary
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.

Title
TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix
Summary
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.

Unauthenticated TLS 1.3 KeyUpdate record can cause persistent connection retention and DoS in crypto/tls
Summary
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.

Title
JsBraceDepth Context Tracking Bugs (XSS) in html/template
Summary
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.

Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509
Summary
When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. 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.

Title
OpenTelemetry-Go OTLP HTTP exporters read unbounded HTTP response bodies
Summary
OpenTelemetry-Go is the Go implementation of OpenTelemetry. Prior to 1.43.0, the otlp HTTP exporters (traces/metrics/logs) read the full HTTP response body into an in-memory bytes.Buffer without a size cap. This is exploitable for memory exhaustion when the configured collector endpoint is attacker-controlled (or a network attacker can mitm the exporter connection). This vulnerability is fixed in 1.43.0.

Title
OpenTelemetry-Go has an incomplete fix for CVE-2026-24051: BSD kenv command not using absolute path enables PATH hijacking
Summary
OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.15.0 to 1.42.0, the fix for CVE-2026-24051 changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms. This vulnerability is fixed in 1.43.0.

Summary
opentelemetry-go: BSD kenv command not using absolute path enables PATH hijacking
Details
Summary
The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.
Root Cause
sdk/resource/host_id.go line 42:
if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {
Compare with the fixed Darwin path at line 58:
result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")
The execCommand helper at sdk/resource/host_id_exec.go uses exec.Command(name, arg...) which searches $PATH when the command name contains no path separator.
Affected platforms (per build tag in host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.
The kenv path is reached when /etc/hostid does not exist (line 38-40), which is common on FreeBSD systems.
Attack
- Attacker has local access to a system running a Go application that imports
go.opentelemetry.io/otel/sdk - Attacker places a malicious
kenvbinary earlier in$PATH - Application initializes OpenTelemetry resource detection at startup
hostIDReaderBSD.read()callsexec.Command("kenv", ...)which resolves to the malicious binary- Arbitrary code executes in the context of the application
Same attack vector and impact as CVE-2026-24051.
Suggested Fix
Use the absolute path:
if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); err == nil {
On FreeBSD, kenv is located at /bin/kenv.
