CVE-2025-22804 details an improper neutralization of input during web page generation, specifically allowing for stored Cross-site Scripting (XSS) within the Paul Bearne Author Avatars List/Block plugin. The vulnerability affects versions from n/a through 2.1.23 and poses a risk primarily through network attack vectors. With a CVSS score of 6.5, this vulnerability is classified as medium severity, indicating a significant risk that organizations should not overlook.
The risk to organizations includes unauthorized access and manipulation of user data, which could lead to further attacks or data breaches. Although the vulnerability has been deferred in its status, it is critical for organizations to address this issue promptly to mitigate the potential impact. Organizations should prioritize patching immediately.
As of now, no public exploits or proof of concepts have been confirmed, but the risk remains due to its exploitable nature. Users are urged to keep their software up to date and employ security best practices to minimize exposure to this vulnerability.
Given the low user interaction required and the low attack complexity, this vulnerability could be exploited by malicious actors with minimal effort, increasing the urgency for organizations to address it in their priority patch cycle.
In summary, organizations utilizing the Paul Bearne Author Avatars List/Block plugin must assess their exposure and remediate this vulnerability effectively.
Vulnerability Details
The vulnerability, classified under CWE-79 for improper neutralization of input during web page generation, allows stored XSS in the affected plugin. The vulnerability was published on January 9, 2025, and has a CVSS score of 6.5, indicating medium severity. This requires organizations to ensure that they are running versions later than 2.1.23 or apply patches as they become available.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly sanitize user input, which can be exploited to inject malicious scripts into the web page. The attack vector is network-based, and the attack complexity is low. The required privileges are also low, meaning that even users with minimal access could potentially exploit this vulnerability. User interaction is required, as an attacker would need to trick users into interacting with the malicious content.
The confidentiality, integrity, and availability impacts are all classified as low, but the potential for damage, including data theft or manipulation, underscores the importance of addressing this issue promptly.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-22804 is significant. Organizations leveraging the affected plugin should consider the potential for exploitation, which can lead to unauthorized access and data breaches. The blast radius of this vulnerability is not limited to a single user but can extend to all users of the system, depending on the nature of the attack. Organizations should schedule remediation and ensure they are monitoring for any suspicious activities related to this vulnerability.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
