Machine-written summary

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

Emissary versions before 8.43.0 have an OS command injection flaw in Executrix. A place author who can set the IN_FILE_ENDING or OUT_FILE_ENDING configuration keys to shell metacharacters can run arbitrary commands in the JVM's security context when the place processes a payload. Upgrade to Emissary 8.43.0.
