CVE-2026-25776 represents a code injection vulnerability discovered in Movable Type, a content management system developed by Six Apart Ltd. This flaw allows an attacker to inject and execute arbitrary Perl scripts, potentially gaining unauthorized access and control over the system. The vulnerability affects versions 8.0.9 through 9.1.0 of Movable Type. A security patch addressing this issue has been released in version 9.1.1.
The impact of this vulnerability is severe. Successful exploitation allows an attacker to inject and execute arbitrary Perl code. This could lead to complete system compromise, including data exfiltration, modification, or deletion. An attacker could potentially gain access to sensitive user data, modify website content, or even pivot to other systems on the network. The ability to execute arbitrary code makes this vulnerability particularly dangerous, as it bypasses many standard security controls. The potential for remote code execution (RCE) significantly expands the attack surface.
CVE-2026-25776 was publicly disclosed on 2026-04-08. As of this writing, there are no publicly available proof-of-concept exploits. The vulnerability is not currently listed on CISA KEV. Given the CRITICAL CVSS score and the potential for RCE, this vulnerability warrants immediate attention and patching.

The primary mitigation is to immediately upgrade Movable Type to version 9.1.1 or later. If upgrading is not immediately possible, consider implementing temporary workarounds. While a direct workaround is not readily available, restricting Perl execution within the Movable Type environment, if feasible, could reduce the attack surface. Review and harden server configurations to limit the potential impact of successful exploitation. Monitor system logs for suspicious Perl script execution attempts. After upgrading, confirm the vulnerability is resolved by attempting a code injection payload in a non-production environment.
Actualice Movable Type a la versión 9.1.1 o posterior para mitigar la vulnerabilidad de inyección de código. Esta actualización corrige la forma en que se procesan ciertas entradas, previniendo la ejecución de scripts Perl arbitrarios. Consulte las notas de la versión para obtener instrucciones detalladas de actualización.
