This vulnerability allows exploiting incorrectly configured access control security levels in the Zoho CRM Lead Magnet plugin. With a CVSS score of 5.4, this medium severity issue affects versions from n/a through 1.8.1.9. Organizations using this plugin should be aware of the potential risks associated with this vulnerability, as it could lead to unauthorized access.
Risk to organizations includes potential unauthorized access to sensitive data, which can result in data leakage or integrity issues. Given the nature of the vulnerability and its impact on access control, organizations should prioritize patching immediately to prevent exploitation.
As of now, there are no known public exploits or proof of concept (PoC) available for CVE-2026-24595. However, organizations should not become complacent, as the absence of known exploits does not eliminate the risk. Continuous monitoring and timely updates are essential.
Organizations should address this vulnerability in their priority patch cycle to mitigate potential risks associated with unauthorized access and maintain the security integrity of their systems.
Vulnerability Details
The official CVE description states that this vulnerability is related to missing authorization in the Zoho CRM Lead Magnet plugin, allowing exploitation of incorrectly configured access control security levels. It is classified under CWE-862.
The CVSS score of 5.4 indicates a medium severity level, with a network attack vector and low attack complexity. Privileges required are low, and user interaction is not necessary. This means that an attacker can exploit the vulnerability remotely without needing any specific privileges or user actions.
The vulnerability was published on January 23, 2026, and the last modification date was April 28, 2026. Organizations using the affected version should be vigilant and take immediate steps to secure their systems.
Technical Analysis
The root cause of the vulnerability lies in the lack of proper authorization checks in the Zoho CRM Lead Magnet plugin, which leads to incorrectly configured access control security levels. This misconfiguration enables unauthorized users to gain access to resources they should not be able to access.
The attack vector is network-based, meaning that an attacker can potentially exploit this vulnerability from any location with network access to the affected application. The complexity of the attack is low, as it does not require advanced skills or resources.
Privileges required to exploit the vulnerability are low, meaning that attackers do not need significant access to execute their attack. Additionally, no user interaction is required, which makes it easier for an attacker to exploit the vulnerability without alerting the target.
The confidentiality impact is none, while the integrity and availability impacts are low. This indicates that while unauthorized access may occur, it may not significantly compromise the overall system integrity or availability.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability is notable. Organizations using the affected version of the Zoho CRM Lead Magnet plugin must recognize that incorrect access control can lead to unauthorized exposure of sensitive data. This could have serious implications, including potential data leakage and trust erosion among customers.
The blast radius potential is moderate, as the vulnerability could affect users with access to the plugin. Organizations should assess how this vulnerability may impact their overall security posture and customer trust.
Given the CVSS score of 5.4 and the lack of active exploitation, organizations should still address this vulnerability in their priority patch cycle. This is crucial to maintaining the integrity and security of their systems.
