CVE-2026-106056
HighCVSS 7.5Summary
Rundeck before version 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.
Risk Assessment
An authenticated attacker could execute arbitrary commands on Windows nodes with executor privileges, potentially leading to system compromise or data theft.
Recommendation
Update Rundeck to version 6.2.0 or later, which includes a fix for this vulnerability.

Rundeck before 6.2.0 contains a path traversal vulnerability that allows users holding only the project configure ACL to read arbitrary server files by setting resources.source.N.config.file to any absolute path. Attackers can retrieve file contents through editProjectNodeSourceFile or the apiSourceGetContent endpoint to obtain database passwords, LDAP bind credentials, and other projects' data.
- CVE-2026-92763High
Rundeck through 6.2.1 fails to properly authorize the importConfig and importNodesSources parameters in the project archive import endpoint. Attackers with only the import action can replace project configuration files including security-relevant settings like node executors and SSH key paths that affect job execution.
