CVE-2025-22511 is a medium-severity vulnerability related to stored cross-site scripting (XSS) in the Ella Van Durpe Slides & Presentations plugin. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users, potentially compromising user data and security. The vulnerability affects all versions of the plugin up to and including version 0.0.39.
This vulnerability has a CVSS score of 6.5, indicating a medium risk level. Organizations utilizing the affected plugin should be aware of the potential impact this vulnerability may have on their systems and take necessary actions to protect against exploitation.
Risk to organizations includes unauthorized access and manipulation of user data, especially for users who have low privileges but can interact with the vulnerable plugin. Organizations should prioritize patching immediately.
Currently, there is no confirmed public exploit available for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should proactively implement security measures.
Vulnerability Details
The vulnerability is classified as improper neutralization of input during web page generation, specifically identified as CWE-79. The issue arises within the Ella Van Durpe Slides & Presentations plugin, leading to stored XSS vulnerabilities. The plugin versions affected range from n/a through version 0.0.39.
The CVSS 3.1 vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, which indicates that the attack vector is through the network, the attack complexity is low, and user interaction is required to exploit the vulnerability.
Technical Analysis
The root cause of CVE-2025-22511 stems from inadequate sanitization of user input that is processed by the plugin. Attackers may leverage this flaw to inject harmful scripts that execute within the context of another user's session.
The attack vector is network-based, requiring low complexity and low privileges, meaning that an attacker does not need extensive access to exploit the vulnerability. User interaction is required, as the victim must access a compromised page for the attack to succeed.
The impacts of this vulnerability include low confidentiality, integrity, and availability impact, indicating that while the potential for exploitation exists, the immediate consequences may be limited.
Risk & Impact Analysis
Organizations leveraging the Ella Van Durpe Slides & Presentations plugin face risks associated with the potential for unauthorized script execution. Exploitation could lead to data theft, session hijacking, or spreading malware to other users.
With a CVSS score of 6.5, the urgency for organizations to address this vulnerability is classified as medium, suggesting that it should be incorporated into the upcoming patch cycle. Organizations should assess the risk based on their deployment scenarios and user interactions.
