Markusproject maintains Markus, an academic course-management and assignment-grading platform, with a vulnerability profile concentrated on this single product. Vulnerabilities affecting the platform skew toward serious outcomes and recur through web-application and file-handling weakness classes including unrestricted file uploads, authorization bypasses tied to user-controlled keys, path traversal, cross-site scripting, and improper handling of compressed data—issues characteristic of systems that process student submissions and manage access controls. Defenders deploying Markus in production should prioritize patching and restrict file-upload permissions; current severity and exploitation activity are shown alongside this summary.
