TeamCity ↗
Auto-added after CISA flagged TeamCity 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".

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.
