Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: WebSocket terminal sessions could be hijacked by untrusted local or web-based clients. Remediation required implementing single-use authentication tokens via IPC and timing-safe token comparisons to guarantee that only the authorized Lens frontend can initiate shell sessions.

Command Injection: Resolving the UNIX shell environment relied on unsafe argument interpolation, allowing arbitrary command execution when spawning processes. This was mitigated by implementing robust single-quote escaping for shell parameters.

SSRF: The local kubectl auth proxy initially accepted connections from any host and used wildcards for target routing, permitting local or cross-origin attackers to reach cluster APIs. The fix restricted `--accept-hosts` to the specific target cluster hostname and introduced randomized API path prefixes.
