CVE-2025-56807 is a cross-site scripting (XSS) vulnerability identified in FairSketch RISE Ultimate Project Manager & CRM version 3.9.4. The vulnerability allows an authenticated administrator user to inject and store malicious JavaScript payloads via the file explorer functionality within the admin dashboard, specifically when creating new folders. This stored XSS flaw means that the malicious script is saved on the server and can be executed whenever an administrator or other privileged user accesses the affected interface or views the folder listing. Since the injection point is within the administrative interface, exploitation requires administrative privileges, which limits the initial attack vector to insiders or compromised admin accounts. However, once exploited, the attacker could leverage the XSS to execute arbitrary JavaScript in the context of the admin dashboard, potentially leading to session hijacking, credential theft, privilege escalation, or further compromise of the CRM system. The lack of a CVSS score and absence of known exploits in the wild suggest this vulnerability is newly disclosed and may not yet be widely exploited. The vulnerability arises from insufficient input validation or output encoding in the folder creation feature of the file explorer, allowing script tags or event handlers to be stored and executed. Given the nature of the affected software—a project management and CRM platform—successful exploitation could undermine the confidentiality and integrity of sensitive business data managed within the system. The vulnerability is specific to version 3.9.4, and no patch or mitigation guidance has been published at the time of disclosure.

For European organizations using FairSketch RISE Ultimate Project Manager & CRM 3.9.4, this vulnerability poses a significant risk to the confidentiality and integrity of project management and customer relationship data. Since the attack requires administrative access, the primary risk vector is through compromised or malicious insiders or attackers who have already gained admin credentials. Exploitation could lead to unauthorized access to sensitive business information, manipulation of project data, or disruption of CRM operations. In regulated industries common in Europe, such as finance, healthcare, or manufacturing, such a compromise could lead to compliance violations under GDPR or sector-specific regulations, resulting in legal and financial penalties. Additionally, the ability to execute arbitrary scripts in the admin interface could facilitate lateral movement within the network or deployment of further malware. The absence of known exploits in the wild currently limits immediate widespread impact, but organizations should treat this vulnerability seriously due to the privileged context and potential for significant damage if exploited.

European organizations should take immediate steps to mitigate this vulnerability despite the lack of an official patch. First, restrict administrative access to the FairSketch RISE Ultimate Project Manager & CRM to only trusted personnel and enforce strong authentication mechanisms, such as multi-factor authentication (MFA), to reduce the risk of credential compromise. Conduct a thorough review of admin accounts and revoke or disable any unnecessary or inactive accounts. Implement strict input validation and output encoding controls on the folder creation functionality if possible, or apply web application firewall (WAF) rules to detect and block malicious script payloads targeting the file explorer interface. Monitor administrative logs for suspicious activity, particularly unusual folder creation events or unexpected JavaScript payloads. If feasible, isolate the CRM system within a segmented network zone to limit potential lateral movement. Finally, maintain close contact with the vendor for updates and patches addressing this vulnerability and plan for prompt application once available.
