About this tag
CVE-2026-3479 is a low-severity security vulnerability in CPython's pkgutil.get_data() function. The issue allowed path traversal because the function did not enforce documented path-safety rules, enabling callers to pass resource names that could escape the intended package-relative directory. The Python Software Foundation assigned a low CVSS score, but the bug is notable for breaking a documented security boundary in a widely used standard-library helper.
