Measuring AI Security: Separating Signal from Panic

The conversation around AI security is full of anxiety. Every week, new headlines warn of jailbreaks, prompt injection, agents gone rogue, and the rise of LLM-enabled cybercrime. It’s easy to come away with the impression that AI is fundamentally uncontrollable and dangerous, and therefore...

CVE-2026-0651

CVE-2026-0651 is a path traversal vulnerability in TP-Link Tapo C260 v1, D235 v1, and C520WS v2.6 where the HTTP server mishandles GET paths: it normalizes paths, but if decoding of URL-encoded input fails it falls back to the raw path, enabling crafted URL-encoded traversal sequences to escape t...

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...
