CVE-2026-3264 is a vulnerability identified in the go2ismail Free-CRM product, specifically impacting an unknown functionality within the Administrative Interface. The issue involves execution after redirect, meaning that an attacker can manipulate the redirect logic to execute unauthorized code or commands remotely. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and does not require authentication (PR:L) or user interaction (UI:N). The vulnerability affects confidentiality, integrity, and availability at a low level (VC:L, VI:L, VA:L). The product uses a rolling release model, which obscures precise versioning information, making it difficult to determine all affected releases or to track patches. The vendor was contacted but did not respond, and no official patches or mitigations have been published. Public exploit code has been disclosed, increasing the risk of exploitation, although no active exploitation in the wild has been reported. The CVSS 4.0 base score is 5.3, reflecting a medium severity level. This vulnerability could allow attackers to bypass security controls in the administrative interface, potentially leading to unauthorized actions or data exposure within the CRM environment.

The vulnerability could allow remote attackers to execute unauthorized code or commands within the administrative interface of go2ismail Free-CRM, potentially leading to unauthorized access to sensitive customer data, manipulation of CRM records, or disruption of CRM services. Although the impact on confidentiality, integrity, and availability is rated low individually, combined they could degrade trust in the CRM system and affect business operations relying on it. The lack of authentication requirement and user interaction increases the risk of automated exploitation. Organizations using this CRM system may face data breaches, operational disruptions, or compliance violations if exploited. The absence of vendor response and patches prolongs exposure, increasing the window of opportunity for attackers. Given the public disclosure of exploit code, the risk of exploitation may rise over time, especially in environments where the CRM is internet-facing or insufficiently segmented.

Organizations should immediately audit their deployment of go2ismail Free-CRM to identify affected versions, despite the rolling release complexity. Network segmentation and restricting access to the administrative interface to trusted IP ranges can reduce exposure. Implementing web application firewalls (WAFs) with rules to detect and block suspicious redirect manipulations may provide interim protection. Monitoring logs for unusual redirect or execution patterns is critical to detect exploitation attempts early. Until an official patch is released, consider disabling or limiting administrative interface access where feasible. Engage with go2ismail support channels regularly to obtain updates or patches. Additionally, applying general security best practices such as enforcing strong access controls, multi-factor authentication on administrative accounts, and regular backups will help mitigate potential damage. Organizations should also prepare incident response plans specific to CRM compromise scenarios.
