CVE-2026-3265 identifies an improper authorization vulnerability in the go2ismail Free-CRM product, specifically within an unspecified part of the /api/Security/ endpoint of the Security API component. This flaw allows an attacker to bypass authorization checks remotely, potentially enabling unauthorized access or actions within the CRM system. The vulnerability affects all versions up to the commit b83c40a90726d5e58f0cc680ffdcaa28a03fb5d1, but due to the product's rolling release strategy, exact versioning details are unclear. The attack vector is network-based with low complexity and does not require user interaction, but it does require the attacker to have low-level privileges (PR:L). The impact on confidentiality, integrity, and availability is limited but present, as unauthorized actions could compromise sensitive customer data or disrupt CRM operations. The vendor was contacted early but did not respond or provide a patch, and no official remediation is currently available. Public exploit code exists, increasing the risk of exploitation. The CVSS 4.0 score of 5.3 reflects a medium severity level, balancing the ease of exploitation with the limited scope of impact. Organizations using go2ismail Free-CRM should be aware of this vulnerability and take immediate steps to mitigate risk while awaiting an official fix.

The improper authorization vulnerability in go2ismail Free-CRM can lead to unauthorized access or manipulation of CRM data and functions. This can compromise the confidentiality of sensitive customer information, affect data integrity by allowing unauthorized changes, and potentially disrupt availability if critical security functions are bypassed. Organizations relying on this CRM for customer relationship management may face data breaches, loss of customer trust, regulatory compliance issues, and operational disruptions. Since the exploit is publicly available and the vendor has not issued a patch, the risk of exploitation is elevated. Attackers with low-level privileges could escalate their access or perform unauthorized actions remotely without user interaction, increasing the threat landscape. The medium severity rating indicates a moderate but significant risk, especially for organizations handling sensitive or regulated data.

1. Implement strict network segmentation and firewall rules to restrict access to the /api/Security/ endpoint to trusted internal systems only. 2. Employ strong authentication and authorization mechanisms at the network perimeter and within the application to limit low-privilege user capabilities. 3. Monitor logs and network traffic for unusual or unauthorized API calls targeting the Security API endpoints. 4. Use Web Application Firewalls (WAFs) with custom rules to detect and block exploitation attempts against the vulnerable API paths. 5. Temporarily disable or restrict access to the affected API endpoints if feasible until a patch is released. 6. Conduct regular security audits and penetration tests focusing on authorization controls within the CRM. 7. Maintain up-to-date backups of CRM data to enable recovery in case of compromise. 8. Engage with the vendor or community to track patch releases or updates addressing this vulnerability. 9. Educate internal users about the risk and signs of exploitation to enhance detection capabilities.
