Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

AI-suggested

Users should monitor the vendor advisory for updates. Until a fix is available, restrict user roles to trusted users only and consider disabling or limiting access to the affected AJAX functionality if possible. Implementing custom capability checks or nonce verification in the AJAX handler can mitigate the risk.

Description

Builderall Cheetah For WordPress plugin versions up to 3.0.2 contains a missing authorization vulnerability. The wp_ajax_ba_cheetah_disable AJAX handler lacks capability and nonce verification, allowing authenticated users with Subscriber-level access or higher to disable the page builder layout on arbitrary posts, including those owned by other users. This is achieved by modifying the _ba_cheetah_enabled post meta to false via user-controlled input.

Impact

The vulnerability allows authenticated attackers with Subscriber-level privileges or higher to modify post metadata on arbitrary posts, disabling the page builder layout. This results in integrity impact by unauthorized modification of content presentation but does not affect confidentiality or availability. The CVSS score is 4.3 (medium severity), reflecting low complexity and limited impact confined to integrity.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
