CVE-2026-13609
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
The Frontend Admin by DynamiApps WordPress plugin before version 3.29.9 decodes HTML entities in a submitted form field value after sanitizing it, which restores HTML tags that the sanitizer had neutralized. A double-encoded payload submitted by an unauthenticated visitor is therefore stored as a live tag and later output without escaping on the plugin's front-end display surfaces, resulting in stored cross-site scripting that executes in the browser of any user, including an administrator, who views a page displaying the submitted value.
Risk Assessment
An unauthenticated attacker can inject a malicious script that executes in the browsers of all users, including administrators, leading to session theft, defacement, or data theft.
Recommendation
Update the Frontend Admin by DynamiApps plugin to version 3.29.9 or later.
Other vulnerabilities in Frontend Admin by DynamiApps
See all- CVE-2026-75816Critical
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.
- CVE-2026-18432Critical
The Frontend Admin by DynamiApps plugin for WordPress up to version 3.29.9 contains a privilege escalation vulnerability. It stems from a flawed condition in the `ActionUser::conditions_logic()` function that skips the authorization check when the user ID is a string, allowing an attacker to escalate privileges to administrator.
- CVE-2026-66662Critical
The Frontend Admin by DynamiApps plugin versions up to 3.29.10 contain an Unauthenticated Privilege Escalation vulnerability. A remote unauthenticated attacker can escalate privileges in the system.
- CVE-2026-42722High
Administrator SQL Injection in Frontend Admin by DynamiApps versions up to 3.29.13.
- CVE-2026-6243Medium
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via kses bypass / mutation XSS in all versions up to and including 3.28.36. This is due to the 'get_dynamic_values' function performing text-level find-and-replace operations on post content without HTML-aware parsing. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
- CVE-2026-81347Medium
The Frontend Admin by DynamiApps WordPress plugin before version 3.29.13 does not properly validate a user-controllable directory path before deleting files within it, allowing unauthenticated attackers to delete index.php and .htaccess files outside the intended directory, including the WordPress root, which can render the site inoperable. Successful exploitation requires a non-default form configuration.
- CVE-2026-19952High
The Frontend Admin by DynamiApps plugin for WordPress up to version 3.29.12 is vulnerable to arbitrary file deletion due to insufficient file path validation in the move_folders function. This allows unauthenticated attackers to delete arbitrary files on the server, which can lead to remote code execution when the right file is deleted (such as wp-config.php). Exploitation is possible without authentication when a form is configured with public visibility.
- CVE-2026-81346Medium
The Frontend Admin by DynamiApps WordPress plugin before 3.29.11 does not perform a capability check on one of its AJAX actions, allowing any authenticated user, such as a subscriber, to delete arbitrary membership plans.
- CVE-2026-66638Medium
Cross Site Scripting (XSS) vulnerability in Frontend Admin by DynamiApps in versions up to 3.29.10. A user with Contributor role can inject malicious script.
- CVE-2026-15606High
The Frontend Admin by DynamiApps plugin for WordPress, in all versions up to and including 3.29.9, is vulnerable to authorization bypass. Authenticated attackers with subscriber-level and above permissions can reset the password of any user, including administrators, leading to full account takeover and complete site compromise.
