CVE-2026-64966 is a path traversal vulnerability in the ZIP extraction functionality of ATutor, confirmed in version 2.2.4. An attacker with instructor privileges can upload and extract a specially crafted ZIP archive containing traversal sequences so that extracted files are written outside the intended destination directory. This can be leveraged to place a server-executable script in the web root, resulting in remote code execution under the privileges of the web server process. The product is no longer actively supported and no fix is available.
