CVE-2026-0919: TP-Link Tapo c220 Firmware

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

The HTTP parser of Tapo C210 v3, C220 v1 and C520WS v2 cameras improperly handles requests containing an excessively long URL path. An invalid‑URL error path continues into cleanup code that assumes allocated buffers exist, leading to a crash and service restart. An unauthenticated attacker can force repeated service crashes or device reboots, causing denial of service.

Affected products

• TP-Link Tapo c220 Firmware: before 1.4.2 (fixed in 1.4.2)
• TP-Link Tapo c520ws Firmware: before 1.2.3 (fixed in 1.2.3)
