Description Guilherme de Almeida Suckevicz 2023-03-17 17:56:37 UTC

The Mustache pix helper contained a potential Mustache injection risk if combined with user input (note: This did not appear to be implemented/exploitable anywhere in the core Moodle LMS). 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.
