Exploited or KEV-listed · 0

Records at severity 3–4 (exploitation confirmed by CISA, the vendor or reporting) and records flagged as listed in CISA KEV. The KEV flag is the classifier’s cisa-kev tag or a source on the KEV catalog; it is recorded when the collector sees the listing, so a missing flag does not mean a CVE is absent from the catalog.

No record for Cursor has confirmed exploitation or a KEV flag.
