CVE-2024-39330

Name	CVE-2024-39330
Description	An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. Derived classes of the django.core.files.storage.Storage base class, when they override generate_filename() without replicating the file-path validations from the parent class, potentially allow directory traversal via certain inputs during a save() call. (Built-in Storage sub-classes are unaffected.)
Source	CVE (at NVD; CERT, LWN, oss-sec, fulldisc, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
