Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Inadequate handling of trailing spaces or periods in filenames (such as '.. ') during sanitization can strip safe characters and inadvertently expose path traversal sequences like '..'.
Path Traversal: Swallowing exceptions during post-sanitization validation allows invalid filenames or paths to bypass checks entirely, undermining the library's primary sanitization guarantees.
Path Traversal: Windows reserved filenames (e.g., COM0/LPT0 and superscript numeric variants) can bypass basic reserved name validations if the root name is not extracted correctly from multi-extension structures.
