Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: User-supplied opener files were loaded directly from the filesystem without validation, allowing remote attackers to read arbitrary local files. Remediations introduced strict directory resolution and path component stripping.
Auth Bypass: Incomplete or inconsistent mapping of Discord slash command checks allowed unauthorized users to execute privileged operations. Command grouping and pre-execution decorator validations were implemented to enforce consistent access controls.
Denial of Service: Unhandled exceptions during GPT conversation processing left users permanently locked in an awaiting state or leaked active Discord threads, requiring robust state cleanup and thread locking in try-except blocks.
