The CP Image Store with Slideshow plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.9 due to a logic error in the 'cpis_admin_init' function's permission check. This vulnerability allows authenticated attackers, with Contributor-level access and above, to import arbitrary products via XML, provided that the XML file has already been uploaded to the server.
With a CVSS score of 4.3, this vulnerability is classified as medium severity. Risk to organizations includes unauthorized manipulation of product data, which can lead to further exploitation of the website and its resources. Given the nature of the vulnerability, organizations utilizing this plugin should prioritize addressing it promptly to mitigate potential risks.
As of now, there is no confirmed public exploit available for this vulnerability. However, its existence could allow for serious compromises if not remediated in a timely manner. Organizations should remain vigilant and monitor for any signs of exploitation.
Organizations should prioritize patching immediately. Regular updates and security practices are essential to maintaining the integrity and security of web applications.
Vulnerability Details
The vulnerability arises from a logic error in the permission check of the CP Image Store with Slideshow plugin for WordPress. This failure allows authenticated users with low-level privileges to perform actions that should be restricted, thus constituting an authorization bypass.
The CVSS score of 4.3 indicates a medium severity level, which suggests that while the risk is not critical, it still poses a significant threat that should be addressed. The attack vector is classified as NETWORK with low attack complexity and low privileges required, meaning that an attacker does not need extensive resources to exploit this vulnerability.
The vulnerability was published on January 13, 2026, and the status is currently deferred. The CWE classification associated with this vulnerability is CWE-863, which pertains to authorization problems.
Technical Analysis
The root cause of this vulnerability lies in the inadequate permission checks within the plugin's logic. The 'cpis_admin_init' function fails to properly validate the capabilities of the user attempting to import products, thereby allowing unauthorized access to this feature.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without needing physical access to the server. The complexity of the attack is classified as low, indicating that an attacker with basic knowledge of the system can exploit this vulnerability with relative ease. Privileges required to exploit this vulnerability are low, as even users with Contributor-level access can initiate the exploit.
User interaction is not required, which further increases the risk, as attackers can exploit the vulnerability without any action from the victim. The integrity impact is rated as low, meaning that while data can be manipulated, the overall system integrity remains largely intact. There is no confidentiality or availability impact reported.
Risk & Impact Analysis
Organizations using the CP Image Store plugin should be aware of the potential for unauthorized access and manipulation of product data. This vulnerability highlights the importance of robust permission checks within plugins, as any oversight can lead to significant security risks.
The blast radius of this vulnerability could extend to all users of the affected plugin, potentially leading to data loss or corruption if exploited. Given its medium severity, organizations should address this vulnerability in their priority patch cycle to avoid any exploitation that could lead to unauthorized access and further vulnerabilities.
Organizations must also consider the implications of failing to patch this vulnerability, as it could serve as a vector for more serious attacks or data breaches. The urgency for remediation is high, and organizations should act swiftly to mitigate potential risks.
