CVE-2026-102578: Moodle: sql injection in question bank web service

HighCVSS 8.8 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.34% (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: git.moodle.org moodle 4.5.13, 5.0.9, 5.1.6.
  • Severity is disputed: the assigning authority (CNA) scores it 5.5, NVD 8.8.

Low priority for now. Upgrade to git.moodle.org moodle 4.5.13, 5.0.9, 5.1.6 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in Moodle. An authenticated attacker with access to the question bank web service can submit unsanitized input directly into database queries, resulting in a SQL (Structured Query Language) injection vulnerability. This issue could allow an attacker to view, alter, or delete sensitive data stored in the underlying database.
