JQuery ↗
Auto-added after CISA flagged JQuery as actively exploited (KEV catalog). Version and lifecycle mapping is pending review, so this is assessed at the product level and is never reported as a confident "healthy".
Summary iPlain-English security verdict for JQuery, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
JQuery currently scores 100/100 — healthy. 1 actively-exploited vulnerability (CISA KEV) affects older releases (e.g. CVE-2020-11023) — staying on the latest supported version keeps you clear of it. The latest supported release is 4.0.0. It's on the latest patch with no significant known issues — keep it current.
Disclosure trend iNew CVEs published for JQuery each year (NVD). A higher bar means more disclosures that year — more scrutiny, not necessarily less safe.
Patch priority — what to act on iThe issues to fix first — actively exploited (CISA KEV) first, then by exploitation probability (EPSS), then severity. Each row's "→ fixed in" is the earliest version that patches it; "see advisory" means no fixed version is published.
Most urgent first — actively exploited, then likeliest to be exploited.
