When an administrator initiates an account deletion, the system invokes an internal maintenance routine to clean up cryptographic keys associated with the target account. Malformed account names previously accepted by Fabric OS can cause the execution of embedded shell metacharacters, triggering command injection.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":29.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
