Description Guilherme de Almeida Suckevicz 2023-03-17 18:03:16 UTC 
Insufficient filtering of grade report history made it possible for teachers to access the names of users they could not otherwise access. This flaw affects Moodle versions 4.1 to 4.1.1, 4.0 to 4.0.6, 3.11 to 3.11.12, 3.9 to 3.9.19 and earlier unsupported versions.
