An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-25057 in the wild and no public exploit code.\n\nAffected product: MarkUsProject Markus. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-25057/ (Markdown: https://insights.sbomify.com/CVE-2026-25057/index.md)","id":"CVE-2026-25057","markdown":"https://insights.sbomify.com/CVE-2026-25057/index.md","name":"CVE-2026-25057","record":{"aliases":["GHSA-mccg-p332-252h"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Markus grading system","requires_auth":"high_privilege","summary":"Instructors can achieve remote code execution by uploading a malicious zip file with path traversal entries in the MarkUs assignment configuration upload feature.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"markus","vendor":"markusproject"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"MarkUs is a web application for the submission and grading of student assignments.
