Recurring patterns

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

Terminal Escape Sequence Injection: Unsanitized C1 control characters in terminal rendering paths can allow untrusted input to execute arbitrary terminal commands or spoof output. Future TUI rendering components must strictly filter control characters before outputting to terminal devices.

Insecure Permissions: Creating local Unix domain sockets with default, permissive masks can allow unauthorized local users to connect and interact with the fzf server process, leading to privilege escalation or session hijacking.

Information Disclosure: Failing to destroy temporary proxy files and FIFOs before replacing the process image via 'become' or exec calls can leak selection histories or sensitive user inputs to other local processes.
