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

AnalysisAI

Broken access control in Frontend Admin by DynamiApps (WordPress plugin, versions ≤ 3.29.10) allows subscriber-level authenticated users to perform unauthorized privileged operations, resulting in high availability impact and limited integrity compromise on affected WordPress installations. The flaw stems from missing authorization checks (CWE-862), permitting low-privilege users to invoke restricted plugin functionality without proper capability verification. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.

Technical ContextAI

Frontend Admin by DynamiApps (CPE: cpe:2.3:a:shabti_kaplan:frontend_admin_by_dynamiapps) is a WordPress plugin authored by Shabti Kaplan that enables site administrators to expose frontend-facing forms for editing WordPress posts, users, and custom content types. CWE-862 (Missing Authorization) identifies the root cause: the plugin fails to enforce capability or role checks before executing sensitive operations accessible through its frontend form endpoints. In WordPress's permission model, the 'subscriber' role is the lowest authenticated tier, typically granted to registered site users with no editorial or administrative access. When authorization gates are absent or insufficient, subscribers can reach code paths intended for editors, authors, or administrators - a common flaw in WordPress plugins that register AJAX actions or REST endpoints without nonce or capability validation.

RemediationAI

Update the Frontend Admin by DynamiApps plugin to a version beyond 3.29.10 - the exact patched release version is not confirmed in the available data, so administrators should check the WordPress plugin repository or the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/acf-frontend-form-element/vulnerability/wordpress-frontend-admin-by-dynamiapps-plugin-3-29-10-broken-access-control-vulnerability for the verified fix version before upgrading. As an immediate compensating control, sites with open user registration should temporarily disable new subscriber account creation under Settings > General > Membership in WordPress, reducing the attacker's ability to obtain a qualifying account. Alternatively, if the plugin's frontend forms are not required for subscriber-role users, administrators can restrict plugin-registered endpoints at the web server or WAF layer by blocking requests to the relevant AJAX actions or REST routes identified in the plugin's source. Each workaround reduces attack surface without eliminating the underlying flaw; patching remains the authoritative remediation.
