pydicom and pyLoad Path Traversal Vulnerabilities

pyLoad, a free and open-source download manager written in Python, contains a path traversal vulnerability in versions before 0.5.0b3.dev97 that allows arbitrary file deletion outside the extraction directory during password verification of encrypted 7z archives with non-encrypted headers. Attackers can exploit this vulnerability remotely with low complexity, requiring only user interaction, to delete arbitrary files on the system. This is assigned CVE-2026-32808 with a CVSS score of 8.1 (High severity), though no active exploitation (KEV) or public proof-of-concept has been reported at this time.

Path traversal in pydicom versions 2.0.0-rc.1 through 3.0.1 allows local attackers to read, copy, or delete arbitrary files outside the File-set root directory by crafting malicious ReferencedFileID values in DICOMDIR files. The vulnerability exists because pydicom fails to validate that resolved file paths remain within the intended File-set root before performing file I/O operations like copy(), write(), and remove(). No patch is currently available for affected versions.
