Attack Vectors

Page Builder – AIO WP Builder: #1 Website Builder for WordPress (slug: all-in-one-wp-builder) is affected by CVE-2025-53217, rated Medium severity (CVSS 4.3). The issue can be exploited remotely over the network by an authenticated user who has at least subscriber-level access (or higher).

In practical terms, this risk increases for organizations that allow account creation (newsletters, event registration, customer portals, gated content, partner logins) or have many internal WordPress users. Any compromised low-privilege account (e.g., from password reuse or phishing) can also become an entry point.

Security Weakness

The vulnerability is described as a missing authorization / capability check on a function in AIO WP Builder versions up to and including 2.0.2. When a plugin fails to verify that a user is allowed to perform a given action, WordPress may accept requests from roles that should not have that power.

According to the published advisory, this weakness makes it possible for an authenticated attacker (subscriber and above) to perform an unauthorized action. The public information does not specify the exact action, so risk should be evaluated with a conservative mindset—especially if this plugin is installed on revenue-generating or regulated sites.

Technical or Business Impacts

Even at Medium severity, missing authorization vulnerabilities can create meaningful business exposure because they undermine role-based controls. Depending on what the affected function does in your specific environment, potential outcomes may include unwanted changes to site content or configuration performed by a low-privilege account.

From a business-risk perspective, the most common impacts include:

• Brand and campaign risk: Unauthorized edits to landing pages, CTAs, or tracking elements can disrupt conversion performance and undermine campaign reporting.
• Operational disruption: Unapproved changes may trigger incident response, downtime, or emergency rollbacks—pulling time from marketing, IT, and leadership.
• Compliance and audit concerns: If your site supports regulated workflows (privacy notices, consent language, customer communications), unauthorized actions—even without confirmed data theft—can create governance and audit complications.
• Increased likelihood of follow-on compromise: Attackers often use “small” unauthorized actions as stepping stones to deeper persistence, SEO spam, or fraud.

Remediation note: The advisory states there is no known patch available at this time. Based on your risk tolerance, mitigations may include uninstalling the affected plugin and replacing it, minimizing the number of subscriber-level accounts, disabling open registration if not required, enforcing strong authentication (unique passwords and MFA where possible), and increasing monitoring for unexpected administrative or content changes.

Similar Attacks

Missing authorization and permission-check issues have repeatedly been used to abuse WordPress sites, especially when plugins expose sensitive actions without properly validating user capabilities. Real-world examples include:

• WP GDPR Compliance plugin vulnerability (Wordfence) — an example of how authorization weaknesses in plugins can lead to serious site compromise.
• ThemeGrill Demo Importer vulnerability (Wordfence) — a widely reported case where insufficient authorization controls enabled high-impact abuse.
