CVE-2025-27296 is a high-severity Missing Authorization vulnerability found in the revenueflex Auto Ad Inserter plugin, which is designed to increase Google Adsense and Ad Manager revenue. This vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially leading to unauthorized access to sensitive data or functionality. The issue affects all versions of the plugin up to and including version 1.5. Given the potential impact, organizations using this plugin should take immediate action.
The vulnerability has been assigned a CVSS score of 7.2, categorizing it as high severity. This score indicates a significant risk to organizations, as the vulnerability can be exploited over a network with low attack complexity and high privileges required for successful exploitation. The urgency for remediation is high, as the potential for unauthorized access could lead to data breaches or other security incidents.
Currently, there is no known public exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should not underestimate the risk, as attackers often develop exploits for vulnerabilities shortly after they are disclosed. Therefore, it is crucial to prioritize updating or removing the affected plugin to prevent any possible exploitation.
Organizations should prioritize patching immediately. Implementing best practices for access control and regularly reviewing plugin configurations can significantly reduce the risk of encountering such vulnerabilities in the future.
The following sections will further detail the specifics of the vulnerability, its risk and impact analysis, and recommended mitigation strategies.
Vulnerability Details
The CVE-2025-27296 vulnerability is characterized as a Missing Authorization issue found in the revenueflex Auto Ad Inserter plugin. Specifically, it arises from the exploitation of incorrectly configured access control security levels. The vulnerability affects the plugin versions that are less than or equal to 1.5, as stated in the official description from Patchstack.
The CVSS score for this vulnerability is 7.2, classified as high severity. This score reflects the significant potential impact on confidentiality, integrity, and availability, with high impacts in all three categories. The attack vector is network-based, and the attack complexity is low, requiring high privileges but no user interaction.
The vulnerability is categorized under CWE-862, indicating a failure to enforce proper authorization mechanisms. This lack of proper controls makes the vulnerability ripe for exploitation, emphasizing the need for immediate remediation.
Technical Analysis
The root cause of CVE-2025-27296 can be traced back to inadequate authorization checks within the revenueflex Auto Ad Inserter plugin. This oversight allows unauthorized users to gain access to functionalities and data that should be restricted. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without needing physical access to the system.
The attack complexity is assessed as low, as attackers do not need to perform complex actions to exploit the vulnerability. High privileges are required for successful exploitation, meaning that an authenticated user with elevated rights can potentially misuse the vulnerability. Importantly, user interaction is not required for exploitation, which increases the risk.
Confidentiality impact is high, as attackers could gain unauthorized access to sensitive information. Integrity is also at risk, as unauthorized changes could be made to data. Finally, availability impact is high, indicating that the vulnerability could affect the operational functionality of the plugin.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-27296 is significant. Organizations using the revenueflex Auto Ad Inserter plugin must recognize that the vulnerability can lead to unauthorized access and potential data breaches. The blast radius for this vulnerability is considerable, as it affects all instances of the plugin up to version 1.5, impacting any organization that has integrated this plugin into their WordPress environment.
Given the CVSS score of 7.2, organizations should classify this vulnerability as high urgency. The potential for exploitation is real, and immediate measures should be taken to patch or mitigate the risk associated with the vulnerability. The urgency is further emphasized by the ease of exploitation and the high impact on confidentiality, integrity, and availability.
