Vulnerability database
Every flaw the U.S. government’s cybersecurity agency (CISA) has confirmed attackers are using, plus the new WordPress plugin and theme bugs published each day, sorted by what they mean for a small business. We refresh it twice a day. If you see something your website or office runs, tell us.

Sep 17, 2026dd-trace-cpp is the Datadog distributed tracing library for C++.CVE-2026-50277 · Other software · DataDog · reported by GitHubHigh 7.5
dd-trace-cpp is the Datadog distributed tracing library for C++. Prior to 2.1.0, dd-trace-cpp parses incoming W3C baggage headers without enforcing DD_TRACE_BAGGAGE_MAX_ITEMS or DD_TRACE_BAGGAGE_MAX_BYTES on the extraction path, even though those limits are enforced during injection. A remote unauthenticated attacker can send a header containing many comma-separated key-value pairs or one very large value, causing per-request hash-map allocation and unbounded CPU and memory consumption. Baggage extraction is enabled by default in most affected tracers unless baggage is removed from DD_TRACE_PROPAGATION_STYLE or DD_TRACE_PROPAGATION_STYLE_EXTRACT, so affected internet-facing services can be denied service. This issue is fixed in version 2.1.0.

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.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
