GHSA-HFVC-G4FC-PQHX opentelemetry-go: BSD kenv command not using absolute path enables PATH hijacking

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/hostid.go line 42: if result, err :=...

GHSA-W8RR-5GCM-PP58 opentelemetry-go: OTLP HTTP exporters read unbounded HTTP response bodies

overview: this report shows that 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 t...

CVE-2026-27144

A flaw was found in the cmd/compile package in the Go standard library. A no-op interface conversion prevented the compiler from correctly identifying non-overlapping memory moves. As a result, the compiler allows unsafe memory move operations to occur at runtime, potentially causing data...

CVE-2026-27143

A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

golang: crypto/x509: excluded subdomain constraint does not restrict wildcard SANs

A flaw was found in the crypto/x509 package in the Go standard library. This vulnerability allows a certificate validation bypass via an excluded subdomain constraint in a certificated chain as it does not restrict the usage of wildcard SANs in the leaf certificate...

cmd/go: cmd/go: Arbitrary file write via malicious pkg-config directive

A flaw was found in cmd/go. An attacker can exploit this by building a malicious Go source file that uses the 'cgo pkg-config:' directive. This allows the attacker to write to an arbitrary file with partial control over its content, by providing a '--log-file' argument to the pkg-config command...
