NVD description

Rundeck before 6.2.0 contains an OS command injection vulnerability that allows authenticated users with job run permission to execute commands on Windows nodes by supplying crafted option values. Attackers can inject cmd.exe metacharacters such as && or | into free-text options, which CLIUtils.quoteWindowsCMDArg wraps in ineffective single quotes, running commands with node executor credential privileges.

    Rundeck on Windows nodes has a quoting bug that turns a job option into a shell command. CVE-2026-106056: anyone with job run permission can slip && or | into a free-text option and run commands with the node's executor credentials. Fixed in 6.2.0. If that executor is a domain service account, that's a lot of reach. https://thecircuitry.to/article/rundeck-before-620-carries-75-cvss-command-injection-flaw-muy3i0ij
