The vulnerability identified as CVE-2025-23886 is characterized as an improper neutralization of input during web page generation, specifically allowing for stored Cross-site Scripting (XSS) attacks. This flaw affects the Chris Roberts Annie plugin, with vulnerable versions ranging from n/a to 2.1.1. The CVSS score for this vulnerability is 6.5, categorizing it as medium severity.
Risk to organizations includes potential unauthorized execution of scripts in the context of users’ browsers, which could lead to data theft or session hijacking. The vulnerability's attack vector is through the network, requiring low privileges and user interaction to exploit.
Given its medium severity, organizations using the affected versions of the Annie plugin should address this vulnerability in their priority patch cycle. The exploitation status confirms that there are no known public exploits or proofs of concept, but the risk remains due to the nature of XSS vulnerabilities.
Organizations should prioritize patching immediately. Regularly updating and monitoring web applications for vulnerabilities will reduce the likelihood of exploitation.
Vulnerability Details
The CVE-2025-23886 vulnerability allows for stored XSS due to improper input handling in the Chris Roberts Annie plugin. This vulnerability affects all versions up to and including 2.1.1. The CVSS version 3.1 score indicates a medium severity, with notable impacts on confidentiality, integrity, and availability.
The attack vector is classified as NETWORK, with low complexity and low privileges required for exploitation. User interaction is necessary, meaning that a user must perform an action that triggers the XSS payload. The confidentiality, integrity, and availability impacts are all rated as low.
Technical Analysis
The root cause of this vulnerability lies in inadequate input validation during web page generation, which fails to neutralize potentially malicious scripts. Attackers may leverage this weakness to inject malicious scripts that execute in the context of the user's session.
The attack complexity is low, as it does not require advanced knowledge or tools to exploit. Low privileges are needed to perform the attack, and user interaction is required to trigger the script, making it somewhat reliant on user behaviors.
In terms of impact, the confidentiality of user data may be compromised, as attackers can capture sensitive information. Additionally, alterations to user data integrity are possible, whereas availability risks remain minimal.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-23886 is significant. Organizations utilizing the affected versions of the Annie plugin are exposed to potential XSS attacks that can be exploited by malicious actors. The blast radius can be considerable, especially if the vulnerability is exploited at scale, allowing attackers to affect multiple users and systems.
Organizations should assess their exposure and prioritize remediation efforts accordingly. The urgency is moderate, as there are currently no known exploits in the wild. However, organizations should remain vigilant and monitor for any changes in the status of this vulnerability.
