Authenticated file read via unvalidated email path
Published Aug 7, 2023 · Updated Oct 3, 2024
Path traversal in PrestaShop before 8.1.1 allows remote authenticated users to read arbitrary server files through the back office. The displayAjaxEmailHTML method builds an email-file path from attacker-controlled input and passes it to file_exists and file_get_contents without first verifying that its resolved path remains under PS_ROOT_DIR. A highly privileged back-office account is required, and files outside the installation are exposed only when server configuration permits traversal beyond the project root.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
