Last modified Jun 17, 2026

CVE-2024-35164 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The terminal emulator of Apache Guacamole 1.5.5 and older does not properly validate console codes received from servers via text-based protocols like SSH. If a malicious user has access to a text-based connection, a specially-crafted sequence of console codes could allow arbitrary code to be executed with the privileges of the running guacd process. Users are recommended to upgrade to version 1.6.0, which fixes this issue.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
