Summary iPlain-English security verdict for Symfony, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
Symfony's security status could not be assessed at the last sync — vulnerability data was unavailable.
Disclosure trend iNew CVEs published for Symfony 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.
No urgent unpatched issues identified. ✓
