Attackers can traverse the file system to reference a reachable WXR file and have the handler publish its contained posts under their identity, enabling publication of attacker-chosen post type, title, content, and metadata.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://docs.stylemixthemes.com/masterstudy-lms/changelog-free-version","tags":[]},{"url":"https://wordpress.org/plugins/masterstudy-lms-learning-management-system","tags":[]},{"url":"https://www.vulncheck.com/advisories/masterstudy-lms-wordpress-plugin-path-traversal-via-stm-lms-step-parameter","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
