CVE-2025-49355 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79 affecting the ikaes Accessibility Press product up to version 1.0.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be stored and later executed in the context of other users’ browsers. This type of vulnerability can lead to a range of attacks including session hijacking, defacement, and potentially privilege escalation if combined with other vulnerabilities. According to the CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L), the attack can be performed remotely over the network with low complexity but requires the attacker to have some level of privileges (high) and user interaction (such as convincing a user to click a link or visit a page). The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable component, potentially impacting the entire system or other connected components. The confidentiality, integrity, and availability impacts are all rated low, but combined they can still cause significant disruption. No patches are currently linked, and no known exploits are reported in the wild, but the vulnerability is published and should be addressed proactively. The vulnerability is particularly relevant for web applications that use Accessibility Press for content management or accessibility features, where user input is accepted and displayed dynamically. Attackers could leverage this vulnerability to inject malicious JavaScript payloads that execute in the browsers of users who view the affected pages, potentially stealing cookies, redirecting users, or performing actions on their behalf.

For European organizations, this vulnerability poses a moderate risk primarily to web-facing applications using ikaes Accessibility Press. The stored XSS can lead to unauthorized disclosure of sensitive information (such as session tokens), manipulation of web content, and disruption of service availability. Organizations handling personal data under GDPR must be particularly cautious, as exploitation could result in data breaches and regulatory penalties. The requirement for authenticated access and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with many users or where privilege escalation is possible. Public sector, educational institutions, and companies with accessibility-focused web platforms may be more exposed. Additionally, the potential for cross-site scripting to facilitate phishing or social engineering attacks increases the overall threat. The lack of current exploits in the wild provides a window for mitigation, but the medium CVSS score indicates that the vulnerability should not be ignored.

1. Apply patches or updates from ikaes as soon as they become available to address CVE-2025-49355. 2. Implement strict input validation and output encoding on all user-supplied data, especially in web page generation contexts, to prevent injection of malicious scripts. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4. Limit user privileges to the minimum necessary to reduce the risk posed by authenticated attackers. 5. Conduct regular security audits and code reviews focusing on input handling and sanitization. 6. Educate users about the risks of clicking unknown links or interacting with suspicious content to reduce successful exploitation via user interaction. 7. Monitor web application logs and user activity for signs of attempted or successful XSS exploitation. 8. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting Accessibility Press. 9. Isolate critical systems and sensitive data from components vulnerable to XSS to minimize impact scope. 10. Maintain an incident response plan that includes procedures for handling XSS incidents and potential data breaches.
