    OpenTelemetry-Go: Eager W3C baggage-property materialization causes bounded memory-allocation amplification

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.0.0-RC1 until version 1.47.0, baggage.Parse and propagation.Baggage.Extract eagerly materialize every W3C baggage property through parseMember, grow property slices, serialize members,…

    opentelemetry-go: AttributeValueLengthLimit is fully bypassed by attribute values composed of valid U+FFFD runes

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From SDK version 1.33.0, SDK log version 0.9.0, and trace version 1.35.0 until version 1.47.0, the AttributeValueLengthLimit and WithAttributeValueLengthLimit truncation paths in sdk/internal/attrnor…

    OpenTelemetry-Go: Log gRPC exporter ignores env TLS certs, bypassing mTLS/pinning

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. Prior to version 0.21.0, the exporters/otlp/otlplog/otlploggrpc package loads OTEL_EXPORTER_OTLP_LOGS_CERTIFICATE, OTEL_EXPORTER_OTLP_CERTIFICATE, and related client certificate environment variables…

    OpenTelemetry-Go: BatchProcessor can busy-spin when export buffer is full

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. Prior to version 0.21.0, the go.opentelemetry.io/otel/sdk/log BatchingProcessor can enter a tight CPU loop when attacker-driven log emission fills its asynchronous export buffer while the exporter is…

    OpenTelemetry-Go: UTF-8 replacement rune bypasses attribute length truncation

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.10.0 until 1.33.0, the sdk/trace/span.go attribute truncation path can fail to enforce AttributeValueLengthLimit for string and string-slice attributes containing the valid Unicode rep…

    OpenTelemetry-Go: Exporter config logging may leak endpoint URLs in info logs

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.5.0 to 1.44.0, sdk/trace.NewTracerProvider emits a TracerProvider created internal Info-level diagnostic event whose MarshalLog implementations recursively include span processor, expo…

    OpenTelemetry-Go: Unsynchronized baggage map can panic under concurrent access

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 0.11.0 through 1.44.0, the OpenTracing bridge's bridgeSpan contains an unsynchronized extraBaggageItems map which can cause a panic. Because Go maps are not safe for concurrent read/writ…

    CVE-2026-39883 Public exploit

    OpenTelemetry-Go has an incomplete fix for CVE-2026-24051: BSD kenv command not using absolute path enables PATH hijacking

    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 …

    OpenTelemetry-Go OTLP HTTP exporters read unbounded HTTP response bodies

    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 c…

    OpenTelemetry-Go multi-value `baggage` header extraction causes excessive allocations (remote dos amplification)

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.36.0 to 1.40.0, multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. This allows an attacker to amplify cpu and allocations…

    OpenTelemetry-Go Affected by Arbitrary Code Execution via PATH Hijacking

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. The OpenTelemetry Go SDK in version v1.20.0-1.39.0 is vulnerable to Path Hijacking (Untrusted Search Paths) on macOS/Darwin systems. The resource detection code in sdk/resource/host_id.go executes th…
