CVE-2025-67848: Moodle: moodle: authentication bypass via lti provider allows suspended users to gain unauthorized access.

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.42% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: github.com/moodle/moodle/ moodle 4.1.22, 4.4.12, 4.5.8.

Low priority for now. Upgrade to github.com/moodle/moodle/ moodle 4.1.22, 4.4.12, 4.5.8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in Moodle. This authentication bypass vulnerability allows suspended users to authenticate through the Learning Tools Interoperability (LTI) Provider. The issue arises from the LTI authentication handlers failing to enforce the user's suspension status, enabling unauthorized access to the system. This can lead to information disclosure or other unauthorized actions by users who should be restricted.
