Machine-written summary

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

Moodle versions before 4.5.9, from 5.0.0-beta before 5.0.5, and from 5.1.0-beta before 5.1.2 are affected. An attacker with privileged access who restores a specially crafted backup file can cause unintended execution of server-side code, which could lead to full compromise of the Moodle server. Upgrade to 4.5.9, 5.0.5, or 5.1.2, depending on your branch.
