This medium-severity CVE scores 6.5 under NVD CVSS v3. EPSS exploit probability: 1.8% (77th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

The CVE record names the fixed release — apply it.

Autolab is a course management service, initially developed by a team of students at Carnegie Mellon University, that enables instructors to offer autograded programming assignments to their students over the Web. A file disclosure vulnerability was discovered in Autolab's remote handin feature, whereby users are able to hand-in assignments using paths outside their submission directory. Users can then view the submission to view the file's contents. The vulnerability has been patched in version 2.10.0. As a workaround, ensure that the field for the remote handin feature is empty (Edit Assessment > Advanced > Remote handin path), and that you are not running Autolab as root (or any user that has write access to /). Alternatively, disable the remote handin feature if it is unneeded by replacing the body of local_submit in app/controllers/assessment/handin.rb with render(plain: "Feature disabled", status: :bad_request) && return.

The CVE record names the fixed release. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
