|---|---|---|---|---|---|---|
| CVE-2026-27807 | MarkUs is a web application for the submission and grading of student assignments. Prior to version 2.9.4, MarkUs allows course instructors to upload YAML files to create/update various entities (e.g., assignment settings). These YAML files are parsed with aliases enabled. This issue has been patched in version 2.9.4. | [email protected] | 4.9 | 0.06% | 2026-03-06 | 2026-03-12 |
| CVE-2026-25962 | MarkUs is a web application for the submission and grading of student assignments. Prior to version 2.9.4, MarkUs currently extracts zip files without any size or entry-count limits. For example, instructors can upload a zip file to provide an assignment configuration; students can upload a zip file for an assignment submission and indicate its contents should be extracted. This issue has been patched in version 2.9.4. | [email protected] | 6.5 | 0.05% | 2026-03-06 | 2026-03-12 |
| CVE-2026-28405 | MarkUs is a web application for the submission and grading of student assignments. Prior to version 2.9.1, the courses/<:course_id>/assignments/<:assignment_id>/submissions/html_content route reads the contents of a student-submitted file and renders them without sanitization. This issue has been patched in version 2.9.1. | [email protected] | 8.0 | 0.04% | 2026-03-05 | 2026-03-10 |
| CVE-2026-25057 | MarkUs is a web application for the submission and grading of student assignments. Prior to 2.9.1, instructors are able to upload a zip file to create an assignment from an exported configuration (courses/<:course_id>/assignments/upload_config_files). The uploaded zip file entry names are used to create paths to write files to disk without checking these paths. This vulnerability is fixed in 2.9.1. | [email protected] | 9.1 | 0.05% | 2026-02-09 | 2026-02-19 |
| CVE-2026-24900 | MarkUs is a web application for the submission and grading of student assignments. Prior to 2.9.1, the courses/<:course_id>/assignments/<:assignment_id>/submissions/html_content accepted a select_file_id parameter to serve SubmissionFile objects containing a record of files submitted by students. This parameter was not correctly scoped to the requesting user, allowing users access arbitrary submission file contents by id. This vulnerability is fixed in 2.9.1. | [email protected] | 6.5 | 0.03% | 2026-02-09 | 2026-02-19 |
| CVE-2024-51743 | MarkUs is a web application for the submission and grading of student assignments. In versions prior to 2.4.8, an arbitrary file write vulnerability in the update/upload/create file methods in Controllers allows authenticated instructors to write arbitrary files to any location on the web server MarkUs is running on (depending on the permissions of the underlying filesystem). e.g. This can lead to a delayed remote code execution in case an attacker is able to write a Ruby file into the config/in | [email protected] | 7.1 | 2.70% | 2024-11-18 | 2025-09-04 |
| CVE-2024-51499 | MarkUs is a web application for the submission and grading of student assignments. In versions prior to 2.4.8, an arbitrary file write vulnerability accessible via the update_files method of the SubmissionsController allows authenticated users (e.g. students) to write arbitrary files to any location on the web server MarkUs is running on (depending on the permissions of the underlying filesystem). e.g. This can lead to a delayed remote code execution in case an attacker is able to write a Ruby f | [email protected] | 7.1 | 2.26% | 2024-11-18 | 2025-09-04 |
| CVE-2024-47820 | MarkUs, a web application for the submission and grading of student assignments, is vulnerable to path traversal in versions prior to 2.4.8. Authenticated instructors may download any file on the web server MarkUs is running on, depending on the file permissions. MarkUs v2.4.8 has addressed this issue. No known workarounds are available at the application level aside from upgrading. | [email protected] | 5.7 | 0.05% | 2024-11-18 | 2025-09-04 |
