CVE-2024-38525

7.5 highEPSS 0.4%

High (7.5). EPSS 0.4% chance of exploitation in the next 30 days.

dd-trace-cpp is the Datadog distributed tracing for C++. When the library fails to extract trace context due to malformed unicode, it logs the list of audited headers and their values using the `nlohmann` JSON library. However, due to the way the JSON library is invoked, it throws an uncaught exception, which results in a crash. This vulnerability has been patched in version 0.2.2.
