Unknown · Opentelemetry-Go · CVE-2026-41178
**Name of the Vulnerable Software and Affected Versions**
OpenTelemetry Go (affected versions not specified)
**Description**
A denial-of-service issue exists due to the removal of raw-length rejection during baggage header parsing. The `Parse` function processes arbitrarily large or invalid baggage headers and logs errors, allowing a remote client to trigger excessive CPU and memory consumption. Specifically, in `baggage/baggage.go`, the `parseMember` function performs full parsing and `PathUnescape` on members without a size guard. Additionally, in `propagation/baggage.go`, parsing errors from attacker-controlled headers are sent to the global error handler, which by default performs logging, potentially amplifying the impact of oversized inputs.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
