This vulnerability affects versions of the Gallery plugin from an unspecified version up to and including 2.2.1. The CVSS score for this vulnerability is 5.9, indicating a moderate level of risk.
This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to unauthorized actions taken on behalf of the users. Risk to organizations includes exposure to data breaches, session hijacking, and website defacement. Given the nature of stored XSS, the impact can be significant if exploited.
Currently, there are no known exploits or proofs of concept available for CVE-2025-26778. However, this does not diminish the urgency for organizations to secure their systems. Organizations should prioritize patching this vulnerability to prevent potential exploitation.
Organizations should address this vulnerability in their next patch cycle to mitigate the associated risks effectively.
Vulnerability Details
The official description of CVE-2025-26778 states that it is caused by improper neutralization of input during web page generation, leading to stored XSS vulnerabilities in the Jordy Meow Gallery plugin. The CVSS score, which is 5.9, indicates a medium level of severity, primarily due to the combination of high privileges required and user interaction necessary for exploitation.
The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The affected version is any version of the Gallery plugin up to 2.2.1. The vulnerability was first published on February 17, 2025.
Technical Analysis
The root cause of CVE-2025-26778 lies in the lack of proper input validation and sanitization within the Jordy Meow Gallery plugin. Attackers can exploit this vulnerability via a network attack vector, as the attack complexity is rated as low. This means that an attacker does not need any special conditions or advanced skills to exploit this vulnerability.
The vulnerability requires high privileges to exploit, meaning that an attacker must have some degree of access to the system. Additionally, user interaction is required for the exploit to be successful, as the malicious script must be executed in the context of another user's session.
The impact of this vulnerability includes potential low confidentiality, integrity, and availability impacts, which underscores the necessity for immediate remediation.
Risk & Impact Analysis
The impact of CVE-2025-26778 poses a real risk to organizations that utilize the Jordy Meow Gallery plugin, particularly those that may not have stringent security measures in place. The potential for stored XSS attacks could enable attackers to compromise user accounts, steal sensitive information, or conduct further attacks on the organization.
This vulnerability should be addressed in the next patch cycle to prevent potential exploitation. Organizations must consider the implications of not addressing this vulnerability, as it could lead to significant consequences such as data loss or reputational damage.
The CVSS score of 5.9 indicates a medium severity level, and organizations should take proactive measures to mitigate this risk effectively.
