CVE-2026-91046 in Addons for Elementor Plugin
Summary
by MITRE • 10/19/2026
The ElementsReady Addons for Elementor WordPress plugin through 6.7.2 does not perform authorization checks that halt execution in several of its settings-save handlers, allowing users with subscriber-level access and above to overwrite the ElementsReady Addons for Elementor WordPress plugin through 6.7.2's stored settings, including its stored API credentials and its feature and template configuration.

The vulnerability identified in the ElementsReady Addons for Elementor WordPress plugin versions up to 6.7.2 represents a critical failure in access control mechanisms within the application's administrative interface. Specifically, several endpoints responsible for saving user-configured settings lack proper authorization verification before processing incoming data requests. In a secure web application architecture, any operation that modifies persistent state or sensitive configuration parameters must strictly verify that the initiating request originates from an authenticated user with sufficient privileges to perform such actions. The absence of these checks means that the server processes write operations based solely on the presence of valid session cookies or authentication tokens associated with lower-privileged accounts, rather than validating role-based permissions against the specific action being requested.
This flaw allows attackers possessing subscriber-level access and above to manipulate critical plugin configurations without authorization. By exploiting this unrestricted settings-save handler, an attacker can overwrite stored API credentials used by the plugin for external service integrations, as well as alter feature flags and template definitions that dictate how content is rendered on the website. The ability to modify API keys is particularly severe because these credentials often grant access to third-party services or internal APIs. If an attacker successfully replaces legitimate API tokens with their own malicious endpoints or stolen keys, they can intercept sensitive data transmitted between the WordPress site and external servers, potentially leading to unauthorized data exfiltration or manipulation of remote resources associated with those accounts.
The operational impact extends beyond simple configuration tampering to include potential privilege escalation scenarios within the broader ecosystem of the WordPress installation. Since template configurations control visual layouts and structural elements of web pages, an attacker could inject malicious scripts or redirect users to phishing sites by modifying these templates. Furthermore, if the plugin interacts with other plugins or themes that rely on shared state or configuration data, corrupting this information could cause widespread instability or create secondary vulnerabilities in dependent systems. The lack of authorization checks effectively bypasses the principle of least privilege, allowing low-level users to perform administrative functions typically reserved for editors, authors, or administrators, thereby undermining the integrity and confidentiality guarantees provided by WordPress's role-based access control system.
From a classification perspective, this vulnerability aligns with CWE-269, which denotes Improper Privilege Assignment, as well as CWE-862, Missing Authorization, where an actor is able to perform actions they are not explicitly allowed to do. In the context of the MITRE ATT&CK framework for enterprise security, this behavior corresponds to techniques involving unauthorized access and potential persistence mechanisms if malicious configurations allow long-term control over site appearance or data flow. The attack vector typically involves crafting specific HTTP POST requests with manipulated parameters targeting the vulnerable settings endpoints, requiring only basic web interaction capabilities rather than complex exploitation chains.
To mitigate this risk, immediate action is required by upgrading the ElementsReady Addons for Elementor plugin to a version that includes proper authorization checks in all administrative handlers. Administrators should verify their current installation status and apply updates provided by the vendor as soon as they become available. In environments where patching cannot be performed immediately, temporary mitigations include restricting access to WordPress admin pages through IP whitelisting or using web application firewalls to block requests that attempt to modify plugin settings without valid administrative session tokens. Additionally, auditing user roles and ensuring that only trusted individuals have subscriber-level accounts can reduce the attack surface available for exploitation of this specific flaw. Regular security assessments should also include testing for broken access control vulnerabilities in all custom plugins and themes integrated into the WordPress environment.
