CVE-2026-24633 describes a Missing Authorization vulnerability in the Passionate Brains Add Expires Headers & Optimized Minify plugin. This vulnerability allows exploiting incorrectly configured access control security levels, which could lead to unauthorized access. The affected versions range from n/a to 3.2.0. Given its medium severity with a CVSS score of 5.3, this vulnerability poses a substantial risk to organizations that utilize this plugin.
Risk to organizations includes potential unauthorized access to sensitive data and system resources. Attackers may leverage this vulnerability to perform actions that should be restricted, thereby compromising the integrity of the affected systems. Organizations should prioritize quickly assessing the impact of this vulnerability on their environments.
As of now, there is no known exploit publicly available, and the vulnerability has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the absence of known exploits does not diminish the urgency of addressing this vulnerability. Organizations should prioritize patching immediately.
Given the nature of this vulnerability, it is crucial for organizations using the affected plugin to take immediate action to mitigate potential risks. Regular updates and patches to the software should be part of an organization's security hygiene.
Vulnerability Details
The vulnerability is classified as a Missing Authorization issue, indicating that there are weaknesses in the access control mechanisms of the affected plugin. The CVSS score of 5.3 suggests a medium severity level, reflecting the impact that this vulnerability could have on confidentiality, integrity, and availability.
This vulnerability affects the Passionate Brains Add Expires Headers & Optimized Minify plugin, specifically versions up to 3.2.0. The official CVE description highlights the potential for exploitation due to incorrectly configured access control security levels.
The vulnerability was published on January 23, 2026, and is categorized under CWE-862, which pertains to missing authorization.
Technical Analysis
The root cause of this vulnerability is the lack of proper authorization checks within the Passionate Brains Add Expires Headers & Optimized Minify plugin. As a result, users without the necessary privileges could potentially access or manipulate data that should be restricted.
The attack vector for this vulnerability is network-based, allowing attackers to exploit it remotely without physical access to the system. The attack complexity is classified as low, meaning that the vulnerability can be exploited easily by an attacker with minimal effort. No privileges are required for exploitation, and user interaction is not needed.
The impact on confidentiality and integrity is none, but the availability impact is rated as low, indicating that while the system's availability may not be severely compromised, unauthorized access could still lead to other forms of exploitation.
Risk & Impact Analysis
The real-world deployment risk for this vulnerability is significant, especially for organizations that rely on the affected plugin for managing HTTP headers. The potential for unauthorized access could lead to data leaks or misconfigurations that affect the overall security posture of an organization.
The blast radius potential is also concerning, as multiple systems could be affected if the vulnerability is exploited in a large-scale environment. Organizations should assess their deployment of the Passionate Brains Add Expires Headers & Optimized Minify plugin and understand the implications of this vulnerability.
Urgency assessment based on the CVSS score indicates that although the score is not in the critical range, organizations should still address this vulnerability in their priority patch cycle due to its potential impact.
