Description Vladimir Vasilev 2026-09-30 08:46:32 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A flaw was found in Moodle's report builder (core_reportbuilder). Insufficient validation of the audience classname allowed arbitrary class instantiation. No exploitable gadget chain leading to a stronger impact (e.g. code execution or data disclosure) has been demonstrated; the flaw is treated here as instantiation of an arbitrary class with no confirmed further primitive.
