Vulnerability Details
CVE-2025-26545 describes a Cross-Site Request Forgery (CSRF) vulnerability in the shisuh Related Posts Line-up-Exactly by Milliard plugin. This issue allows for stored XSS, which can be exploited by malicious actors. The affected versions include 0.0.22 and earlier. The vulnerability has been assigned a CVSS score of 7.1, indicating a high severity level.
The CVSS vector associated with this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, highlighting the attack vector as network-based with low complexity and requiring user interaction. The potential impacts on confidentiality, integrity, and availability are classified as low.
The CWE classification for this vulnerability is CWE-352, which corresponds to Cross-Site Request Forgery (CSRF).
Technical Analysis
The root cause of CVE-2025-26545 stems from improper validation of user requests, which allows attackers to craft malicious requests that can be executed in the context of authenticated users. The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely.
The attack complexity is assessed as low, given that no special privileges are required for exploitation. However, user interaction is necessary, meaning that an attacker must convince a user to perform an action that triggers the CSRF attack.
In terms of impacts, the vulnerability can lead to low confidentiality, integrity, and availability impacts due to the nature of stored XSS, which can allow for data theft or manipulation.
Risk & Impact Analysis
The deployment of the shisuh Related Posts Line-up-Exactly plugin in environments that rely on user-generated content can significantly increase the risk of exploitation. Organizations utilizing this plugin should be aware of the potential for attackers to leverage this vulnerability to perform actions on behalf of users without their consent.
The blast radius for this vulnerability is concerning, as successful exploitation could lead to compromised user accounts and unauthorized access to sensitive data. Organizations should assess their exposure to this vulnerability and prioritize patching.
Given the high CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. The risk remains that an unpatched vulnerability could be exploited, leading to significant security incidents.
