Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Emissary (gov.nsa.emissary:emissary, Maven) versions before 8.39.0 are vulnerable to command injection through the PLACE_NAME configuration value in the Executrix utility, which passes it unsanitized beyond space replacement into a shell command. An attacker who can control configuration values, such as through administrative access or a compromised configuration source, can execute arbitrary commands on the Emissary host. Upgrade to version 8.39.0 or later; until then, make sure PLACE_NAME values contain only letters, digits, underscores, and hyphens.
