Unauthenticated arbitrary file deletion in the MasterStudy LMS WordPress plugin (versions ≤ 3.7.42) allows remote, unauthenticated attackers to delete arbitrary files on the server via path traversal. The CVSS 8.6 vector (AV:N/AC:L/PR:N/UI:N/S:C/A:H) confirms no authentication or user interaction is required and that impact extends beyond the plugin's own scope to server-level files. No public exploit code or CISA KEV listing has been identified at time of analysis, but the zero-prerequisite attack surface makes this a high-priority patch target for all WordPress deployments running the affected plugin.
Broken Access Control in the MasterStudy LMS WordPress plugin (versions up to and including 3.7.41) permits any authenticated subscriber to bypass role-based authorization checks and access data restricted to higher-privilege roles, resulting in high confidentiality impact. The CVSS vector confirms this is network-exploitable with low complexity and no user interaction required beyond holding a subscriber-level account. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low barrier to exploitation on open-registration LMS platforms makes this a credible threat to sensitive course and student data.
Privilege escalation in the MasterStudy LMS WordPress plugin (versions up to and including 3.7.41) enables authenticated subscriber-level users to exceed their intended permissions through incorrect privilege assignment (CWE-266). Discovered and disclosed by Patchstack and tracked as ENISA EUVD-2026-60936, the flaw affects deployments by Stylemix on the WordPress platform worldwide. No public exploit has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
Unauthenticated remote manipulation of user state is possible in StylemixThemes MasterStudy LMS WordPress plugin through version 3.7.39, due to insufficient verification of data authenticity (CWE-345). The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms that no authentication or user interaction is required, allowing any network-accessible attacker to tamper with LMS user state - such as enrollment records, course progress, or quiz scores. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity makes this straightforward to abuse against unpatched installations.
Stored Cross-Site Scripting in the MasterStudy LMS WordPress plugin (versions <= 3.7.27) allows authenticated subscriber-level users to inject malicious scripts that execute in the browsers of higher-privileged users such as administrators. The vulnerability carries a Scope:Changed CVSS vector, meaning successful exploitation breaks the browser security boundary and can impact resources beyond the plugin itself - enabling session hijacking, credential theft, or privilege escalation within the WordPress admin context. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low privilege bar (subscriber role) widens the attacker pool considerably on sites with open or paid user registration.
SQL injection in the MasterStudy LMS WordPress plugin (versions 3.7.25 and earlier) allows authenticated users at the Subscriber privilege level to inject crafted SQL into backend database queries, leading to high-impact disclosure of confidential database contents and limited availability degradation. The flaw was reported by Patchstack and carries a scope-changed CVSS 3.1 score of 8.5; no public exploit identified at time of analysis.
