Answer in brief
CVE-2021-31010 records a High severity vulnerability in CVE Program Container. The current sources mark it as known exploited. The current feed maps Apple/macOS (generic), Apple/macOS (generic), Apple/watchOS (generic), Apple/watchOS (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
