Subscriber Broken Access Control in Frontend Admin by DynamiApps <= 3.29.10 versions.

The flaw stems from missing authorization checks (CWE-862), permitting low-privilege users to invoke restricted plugin functionality without proper capability verification. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid WordPress subscriber-level account on the target site (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H) reflects a moderate-to-high real-world risk profile with an important limiting factor: PR:L confirms exploitation requires an authenticated subscriber account, not unauthenticated access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker registers a free subscriber account on a WordPress site running Frontend Admin by DynamiApps ≤ 3.29.10, or uses a pre-existing low-privilege credential. They then craft an HTTP POST request targeting a plugin endpoint - such as an AJAX action or REST route - that lacks proper capability checks, invoking a privileged operation (e.g., deleting form configurations or disrupting content structures) that causes significant availability degradation. …
