Opentelemetry-java: Quadratic CPU Consumption In W3C Tracestate Parsing

Summary OpenTelemetry Java's W3C trace-context propagator permits excessive CPU consumption when extracting crafted "tracestate" headers, potentially leading to denial of service. Regex backtracking causes quadratic parsing time for headers containing long runs of spaces or tabs without a followi...

CVE-2026-118259

The opentelemetry-java library (versions prior to 1.67.0 ) is vulnerable to a ReDoS-style attack due to quadratic backtracking in the W3CTraceContextPropagator.extract() method. When parsing tracestate headers containing long sequences of spaces or tabs without a trailing comma, the regex delimit...

OpenTelemetry Java resource management error vulnerability

OpenTelemetry Java versions prior to 1.67.0 contain a resource management error vulnerability. This vulnerability arises because W3CTraceContextPropagator.extract uses regular expression delimiters when processing tracestate headers containing long strings of spaces or tabs without subsequent...
