Plain-English Summary
An enjoined party isn't stuck with whatever security was posted at the start. At any point before judgment, that party can move, on reasonable notice, for additional security. If it turns out the surety on the original undertaking has left the state or isn't sufficient, the court can vacate the injunction outright -- unless sufficient security is given within a reasonable time.

The court may vacate the injunction, unless sufficient security is given within a reasonable time.
