CVE-2026-2965 identifies a cross-site scripting (XSS) vulnerability in the 07FLYCMS family of products, including 07FLY-CMS and 07FlyCRM, affecting all versions up to 1.2.9. The vulnerability is located in the /admin/SysModule/edit.html file, specifically within an unknown function of the System Extension Module that processes the Title argument. By manipulating this argument, an attacker can inject malicious JavaScript code that executes in the context of an authenticated administrator's browser session. The attack vector is remote, requiring the attacker to have high privileges (likely administrative access) and user interaction to trigger the payload. The vulnerability does not require authentication bypass but does require the victim to interact with the malicious input. The vendor was notified early but did not respond or provide a patch, and no official fixes are currently available. Public exploit code has been released, increasing the likelihood of exploitation despite no confirmed attacks in the wild. The CVSS 4.0 base score is 4.8 (medium severity), reflecting the moderate impact on confidentiality and integrity with limited availability impact. The vulnerability can be leveraged for session hijacking, privilege escalation, or defacement, compromising the security posture of affected systems. The product is distributed under multiple names, complicating detection and mitigation efforts.

The primary impact of CVE-2026-2965 is on the confidentiality and integrity of affected systems. Successful exploitation allows attackers to execute arbitrary scripts in the context of an authenticated administrator, potentially leading to session hijacking, theft of sensitive information, or unauthorized actions within the CMS or CRM environment. This can result in data leakage, unauthorized configuration changes, or deployment of further malware. Although availability impact is minimal, the compromise of administrative accounts can severely disrupt organizational operations. The lack of vendor response and patches increases the risk exposure, especially as public exploit code is available. Organizations relying on 07FLYCMS and its variants face increased risk of targeted attacks, especially if administrative interfaces are exposed or insufficiently protected. The medium severity rating reflects the need for timely mitigation to prevent exploitation in environments where administrative user interaction is possible.

Given the absence of official patches, organizations should implement immediate compensating controls. First, restrict access to the /admin/SysModule/edit.html interface to trusted IP addresses or VPN-only access to reduce exposure. Implement strict input validation and sanitization on the Title parameter at the web application firewall (WAF) or reverse proxy level to block malicious script payloads. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser. Educate administrators to avoid clicking on suspicious links or inputs that could trigger the XSS payload. Monitor logs for unusual activity or attempts to exploit the Title parameter. Consider isolating or segmenting the CMS/CRM administrative environment from other critical systems. If feasible, migrate to alternative CMS/CRM solutions or versions not affected by this vulnerability. Maintain regular backups and incident response plans to quickly recover from potential compromises. Finally, engage with the vendor or community for updates or unofficial patches.
