An attacker with instructor privileges can upload and extract a specially crafted ZIP archive, causing files to be written outside the intended extraction directory. This allows an attacker to place a server-executable .phtml file in the web root and achieve remote code execution with web server privileges on the underlying server.\n\n\n\n\nProduct is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","score":8.7},"cvss_v3":null,"cwes":["CWE-22"],"references":["https://atutor.github.io/","https://cert.pl/en/posts/2026/08/CVE-2026-64960"],"products":[],"source":"nvd","synced_at":"2026-10-27T10:25:10.590685846+00:00"},"epss":{"cve":"CVE-2026-64966","score":0.00724,"percentile":0.53758,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
