CVE-2025-49341 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Alex Furr PDF Creator Lite software, affecting all versions up to and including 1.2. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to the application, exploiting the trust the application places in the user's browser. In this case, the CSRF flaw facilitates Stored Cross-Site Scripting (XSS), where malicious scripts injected by the attacker are permanently stored within the application and executed in the context of other users' browsers. This combination is particularly dangerous because it can lead to session hijacking, credential theft, and unauthorized actions performed with the victim's privileges. The vulnerability was reserved in June 2025 and published in December 2025, but no CVSS score or patches have been provided yet. The absence of known exploits in the wild suggests it may not be actively targeted, but the risk remains significant due to the nature of the vulnerability. The lack of authentication or user interaction requirements for exploitation increases the threat level. The vulnerability affects the integrity and confidentiality of user data and can impact availability if exploited to perform disruptive actions. The technical root cause likely involves missing or inadequate CSRF protections such as anti-CSRF tokens and insufficient input sanitization allowing stored XSS payloads. Without vendor patches, organizations must rely on compensating controls to mitigate risk.

For European organizations, exploitation of this vulnerability could lead to unauthorized actions performed under the guise of legitimate users, resulting in data breaches, theft of sensitive information, and potential disruption of document processing workflows. Stored XSS can enable attackers to steal session cookies, escalate privileges, or deliver malware payloads, compromising both user and system integrity. Organizations handling sensitive or regulated data, such as financial, legal, or governmental entities, face increased risks of compliance violations and reputational damage. The persistence of malicious scripts within the application can facilitate prolonged attacks and lateral movement within networks. Additionally, the lack of patches means that organizations must proactively implement mitigations to avoid exploitation. The impact is heightened in environments where PDF Creator Lite is integrated into critical document management or business processes, making availability and integrity essential.

1. Implement CSRF protections by ensuring all state-changing requests require a valid, unpredictable anti-CSRF token tied to the user's session. 2. Sanitize and validate all user inputs rigorously to prevent injection of malicious scripts that lead to stored XSS. 3. Restrict sensitive actions to authenticated users and verify user permissions before processing requests. 4. Monitor application logs and network traffic for unusual or unauthorized requests indicative of CSRF or XSS exploitation attempts. 5. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the application context. 6. If possible, isolate PDF Creator Lite usage to segmented network zones to limit potential lateral movement. 7. Engage with the vendor for updates or patches and apply them promptly once available. 8. Educate users about the risks of clicking on suspicious links or executing untrusted content within the application environment. 9. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block CSRF and XSS attack patterns targeting this software.
