CVE-2026-64967Network attack vector

Arbitrary file read via log path traversal

Published Aug 20, 2026 · Updated Aug 20, 2026

Path traversal in the error log viewer in ATutor 2.2.4 allows remote authenticated users to read arbitrary server files. CERT Polska states that the flaw is in the error log viewer, which fails to keep a user-influenced path confined to the logs directory; public sources do not identify the exact parameter or code path. Admin-level access is required, and the impact is limited to files readable by the web server process, with no public evidence of file modification or code execution.
