Auto-added after CISA flagged Archer AX21 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".
Known exploited vulnerability
CISA's Known Exploited Vulnerabilities (KEV) catalog flagged Archer AX21 (TP-Link) as exploited in the wild — that's why IsItPatched started tracking it. The vulnerability that triggered it:
