Unauthenticated file read via unchecked logfile path
Published Jan 2, 2023 · Updated Apr 10, 2025
Arbitrary file read in Welcart e-Commerce before 2.8.5 allows remote attackers to read server files through an unauthenticated request. The functions/content-log.php endpoint uses the logfile query parameter as a file path and returns its contents without validating or restricting the path. No credentials or user interaction are required, and disclosure is limited to files readable by the web-server process.
