The interesting attack surface is untrusted input: serialized PHP values, repair-mode content, regex patterns, and copied output. Reports about parser hangs, misleading output, invalid serialized data marked as safe, terminal or HTML injection, or anything that could leak pasted database content are in scope.
Only the latest release is supported. The tool has zero runtime dependencies by design; if you find that no longer true, that is also a bug worth reporting.
