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.

This CVE Bugzilla entry is for community support informational purposes only as it does not affect a package in a commercially supported Red Hat product. Refer to the dependent bugs for status of those individual community products.

Comment 3 Oblydtus 2024-07-31 12:47:13 UTC
We have also encountered this in our work this academic year. Therefore, for now, we were forced to suspend the application as well as related services and the library. At the moment, students use https://edubirdie.com/write-my-thesis as a third-party source of information. They provide data for research in a wide range of academic topics. But this is currently used as a temporary measure. Please tell me if there is any solution to this problem?
