CVE-2026-26720 is a critical remote code execution vulnerability affecting Twenty CRM versions up to 1.15.0. This vulnerability allows a remote attacker to execute arbitrary code via the local.driver.ts module. With a CVSS score of 9.8, it represents a significant threat to organizations using this software. The low attack complexity combined with the lack of required privileges and user interaction makes it easier for attackers to exploit.
The implications of this vulnerability are severe. A successful attack could lead to unauthorized access and control over the affected systems, allowing attackers to manipulate data, disrupt services, or deploy further exploits. Organizations should prioritize patching this vulnerability immediately to prevent potential breaches.
Currently, there are no known public exploits confirmed. However, the potential for exploitation is high, and organizations must remain vigilant. Given the critical nature of this vulnerability, immediate action is necessary to secure systems.
Organizations should evaluate their deployment of Twenty CRM and ensure they are on the latest patched version to mitigate this risk. The urgency to address this vulnerability cannot be overstated.
Vulnerability Details
This vulnerability allows a remote attacker to execute arbitrary code via the local.driver.ts module in Twenty CRM versions 1.15.0 and prior. It has a CVSS score of 9.8, indicating critical severity due to the potential impacts on confidentiality, integrity, and availability.
The vulnerability falls under CWE-94, which relates to code injection issues. Its exploitability is classified as critical, and it requires no privileges or user interaction, making it particularly dangerous.
Organizations using affected versions of Twenty CRM should take immediate steps to remediate the vulnerability.
Technical Analysis
The root cause of this vulnerability is a flaw in how the local.driver.ts module processes input. This flaw allows attackers to inject arbitrary code into the execution context of the application.
The attack vector is network-based, allowing remote attackers to exploit this vulnerability without physical access to the vulnerable system. The attack complexity is low, as this vulnerability can be exploited without the need for legitimate credentials or user interaction.
Given that the vulnerability has a high impact on confidentiality, integrity, and availability, organizations must be aware of the potential for data breaches and service disruptions.
Risk & Impact Analysis
Risk to organizations includes unauthorized access, potential data loss, and service interruptions. The critical nature of this vulnerability demands immediate attention from security teams. The potential blast radius is significant, affecting all instances of Twenty CRM running the vulnerable version.
Given the CVSS score of 9.8, organizations should prioritize patching this vulnerability immediately. It is essential to incorporate this update within the priority patch cycle to safeguard against potential exploitation.
