Workarounds
ADP: To mitigate this issue, ensure that applications utilizing PyMuPDF, especially those processing untrusted documents, are run within a sandboxed environment with strict limitations on file system write access. Additionally, validate and sanitize all input paths before they are processed by PyMuPDF's `get` function to prevent path traversal.
There are currently no legacy QID mappings associated with this CVE.
