CVE-2026-29181

OpenTelemetry-Go (Go implementation) has a vulnerability in multi-value baggage header extraction: from versions 1.36.0 through 1.40.0, parsing each header field-value independently causes aggregation of members across values, enabling an attacker to trigger excessive CPU and memory allocations a...

CVE-2026-29181 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 by sending many baggage: header lines...
