AI-suggested
Upgrade dd-trace-php to version 1.19.2 or later, where this issue is fixed. Alternatively, disable baggage extraction by removing baggage from DD_TRACE_PROPAGATION_STYLE or DD_TRACE_PROPAGATION_STYLE_EXTRACT to mitigate the risk. No other mitigations are specified.
Description
CVE-2026-50275 is a high-severity vulnerability in DataDog's dd-trace-php library prior to version 1.19.2. It involves the ddtrace_deserialize_baggage function parsing incoming W3C baggage HTTP headers without enforcing limits on the number or size of key-value pairs. This allows a remote unauthenticated attacker to cause unbounded CPU and memory consumption by sending large or numerous baggage items. The issue is fixed in version 1.19.2.
