A remote code execution vulnerability was discovered in Autolab's MOSS functionality, whereby an instructor with access to the feature might be able to execute code on the server hosting Autolab. This vulnerability has been patched in version 2.10.0. As a workaround, disable the MOSS feature if it is unneeded by replacing the body of `run_moss` in `app/controllers/courses_controller.rb` with `render(plain: \"Feature disabled\", status: :bad_request) && return`.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-77","CWE-78"],"references":["https://github.com/autolab/Autolab/security/advisories/GHSA-x5r3-vf3p-3269","https://securitylab.github.com/advisories/GHSL-2022-100_Autolab/","https://github.com/autolab/Autolab/security/advisories/GHSA-x5r3-vf3p-3269","https://securitylab.github.com/advisories/GHSL-2022-100_Autolab/"],"products":["autolabproject:autolab"],"source":"nvd","synced_at":"2026-10-19T21:37:34.931465858+00:00"},"epss":{"cve":"CVE-2022-41955","score":0.01556,"percentile":0.75185,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
