Security Advisory on Multiple Vulnerabilities on Tapo C260 (CVE-2026-0651, CVE-2026-0652, CVE-2026-0653)

Description of Vulnerabilities and Impacts:

CVE-2026-0651: Path Traversal via Local https

On TP-Link Tapo C260 v1, path traversal is possible due to improper handling of specific GET request paths via https, allowing local unauthenticated probing of filesystem paths. An attacker on the local network can determine whether certain files exist on the device, with no read, write or code execution possibilities.

CVSS v4.0 Score: 5.3 / Medium

CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:L/SI:N/SA:N

CVE-2026-0652: Remote Code Execution on Tapo C260 by Guest User

On TP-Link Tapo C260 v1, command injection vulnerability exists due to improper sanitization in certain POST parameters during configuration synchronization. An authenticated attacker can execute arbitrary system commands with high impact on confidentiality, integrity and availability. It may cause full device compromise.

CVSS v4.0 Score: 8.7 /High

CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L

CVE-2026-0653: Insecure Access Control on Tapo D235 and C260

On TP-Link Tapo C260 v1, a guest‑level authenticated user can bypass intended access restrictions by sending crafted requests to a synchronization endpoint. This allows modification of protected device settings despite limited privileges. An attacker may change sensitive configuration parameters without authorization, resulting in unauthorized device state manipulation but not full code execution.

CVSS v4.0 Score: 7.2 /High

CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N
