# iomad: PDF certificate handler lets remote users bypass authorization

Link for people: https://infrastack.ai/live/CVE-2026-113702 (this .md is for agents)

iomad, a Moodle-based learning platform, has an authorization bypass in the PDF certificate handler's pluginfile function (local_iomad_pluginfile in public/local/iomad/lib.php). A remote attacker can use it to access files they should not be able to reach.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed iomad version against the affected ranges up to `4.5.15`, `5.0.11`, `5.1.8` and `5.2.4`
- Look for `public/local/iomad/lib.php` in the Moodle install and confirm whether `local_iomad_pluginfile` matches the patched code

## Fix

- Apply the vendor patch referenced by the sources (commits ac7427130865ce0ed80870813317c87ae3060fa4, 7bf0b10199782e04aa579e9d516e473b164afd1c, db903abdcb3aba124cce670608ae6d7ba5f51a84, 66f7417c5357b7575e39e8be390602156c1a1225); fixed release versions unknown
