Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Attackers can exploit unsanitized file extensions during video processing to write arbitrary files or traverse directories via manipulated paths. Developers should enforce strict extension allowlists and perform path canonicalization.
Format String Injection: Untrusted video filenames containing Python format specifiers can lead to denial of service or information leakage if directly evaluated inside logging templates. Formatting must be separated from translation templates.
Cookie Leakage: Sensitive authentication cookies can be leaked to unauthorized third-party domains if redirect requests do not properly clear or restrict session headers.
