Machine-written summary

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

Moodle versions 2.5.0 to before 2.5.9, 2.6.0 to before 2.6.6, and 2.7.0 to before 2.7.3 are affected. The password generator produces too few possible temporary passwords, so a remote attacker can brute-force a temporary password and gain access to an account. Upgrade to Moodle 2.5.9, 2.6.6, 2.7.3 or later. The source does not list a workaround.
