CVE-2025-23901 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the GravatarLocalCache plugin for WordPress. This vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users. Given the nature of CSRF attacks, an attacker could exploit this vulnerability to gain unauthorized access or manipulate user data without their consent.
The CVSS score for this vulnerability is 7.1, which categorizes it as high severity. Organizations should understand the potential impact of this vulnerability, particularly in environments where the GravatarLocalCache plugin is in use. The attack vector is classified as network-based, meaning it can be exploited remotely without the need for physical access to the target system.
With a low attack complexity and no required privileges for the attacker, this vulnerability poses a significant risk. User interaction is required, which means that an attacker would need to trick a user into executing the malicious request. Organizations are urged to prioritize remediation of this vulnerability immediately.
The vulnerability was published on January 16, 2025, and affects GravatarLocalCache versions up to 1.1.2. Given that the status of this CVE is currently deferred, it is essential for organizations to remain vigilant and monitor for updates regarding the vulnerability's exploitation status.
Vulnerability Details
The official description of CVE-2025-23901 states: 'Cross-Site Request Forgery (CSRF) vulnerability in cybio GravatarLocalCache gravatarlocalcache allows Cross Site Request Forgery. This issue affects GravatarLocalCache: from n/a through <= 1.1.2.' This vulnerability falls under CWE-352, indicating that it is related to CSRF attacks.
The CVSS score of 7.1 indicates a high severity level, reflecting the significant risk this vulnerability poses to organizations. The vulnerability's attack vector is network-based, and it requires user interaction for exploitation. The impacts on confidentiality, integrity, and availability are all considered low.
Technical Analysis
The root cause of this vulnerability stems from a lack of proper validation of user requests, which allows attackers to send forged requests to the server on behalf of authenticated users. The vulnerability can be exploited through the network, making it accessible to remote attackers.
The attack complexity is categorized as low, as attackers do not require any special privileges to exploit the vulnerability. However, user interaction is necessary, meaning that the victim user must be tricked into performing an action that sends the forged request.
The confidentiality, integrity, and availability impacts are all classified as low, indicating that while the potential for unauthorized access exists, the scope of the attack may be limited. However, the ability to perform unauthorized actions remains a serious concern.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-23901 is substantial, particularly for organizations utilizing the GravatarLocalCache plugin. The potential for unauthorized actions to be executed on behalf of users makes this vulnerability particularly concerning.
The blast radius for this vulnerability can extend to all users of the affected plugin, creating a wide impact. Organizations must assess their use of the affected plugin and the potential consequences of exploitation.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. The low EPS score indicates a lower likelihood of exploitation in the wild, but organizations should not underestimate the potential for attackers to leverage this vulnerability.
