Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions before 1.62.0 of opentelemetry-api and opentelemetry-extension-trace-propagators parse oversized baggage without limits, allowing unbounded memory and CPU use. Most Java HTTP servers cap headers at 8 KiB, limiting external attacks. Upgrade to 1.62.0 or later, and set HTTP header size limits at the server or gateway.
