Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Insecure handling of file paths in the media retrieval endpoint allowed requests to escape the intended directory. Developers must ensure path canonicalization and strict prefix validation are consistently applied before calling file-serving utilities.
Remote Code Execution: Evaluating untrusted user-defined Python code in evaluation nodes risks complete control of the local host environment. Moving code evaluation to a strictly sandboxed Pyodide WebWorker isolates the host environment from arbitrary payload execution.
Reflected XSS: Compiling unescaped user-controlled search queries directly into dynamic regular expressions can lead to client-side injection and denial-of-service. Sanitizing regex metacharacters prevents unexpected query compilation and execution behaviors.
