CVE-2026-0651 — Path Traversal on TP-Link Tapo D235, C211, C520WS and C260 via Local https
A path traversal vulnerability was identified TP-Link Tapo C260 v1, D235 v1, C211 v2 and C520WS v2.6 within the HTTP server’s handling of GET requests. The server performs path normalization before fully decoding URL encoded input and falls back to using the raw path when normalization fails. An attacker can exploit this logic flaw by supplying crafted, URL encoded traversal sequences that bypass directory restrictions and allow access to files outside the intended web root. Successful exploitation may allow authenticated attackers to get disclosure of sensitive system files and credentials, while unauthenticated attackers may gain access to non-sensitive static assets.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.3% (30-day exploitation probability)+3
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (TP-Link Systems Inc. Tapo C211 v2, TP-Link Systems Inc. Tapo C260 Firmware, TP-Link Systems Inc. Tapo C260 v1…).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.
