CVE-2026-82538: ILIAS Arbitrary SQL Injection via Repository Trash Table Sort Parameter
ILIAS before versions 9.22, 10.10, and 11.3 contains a SQL injection vulnerability in the repository trash table where the table navigation sort field from HTTP requests is passed directly into the ORDER BY clause of a SQL query without validation against declared sortable columns. Authenticated users with write permission on any container can inject arbitrary SQL through the sort parameter, and because multi-statement execution is enabled in the database layer, stacked queries enable full database read and write access as well as administrator account takeover.

Event History
Frequently Asked Questions
Which users can exploit this issue?
An attacker must be authenticated and have write permission on any container. No user interaction is required once those permissions are available.
Are standard installations affected?
The issue is in the repository trash table's request-controlled sort field. Any affected ILIAS installation where a user can access that functionality with write permission on a container may be exposed.
What is the impact if exploitation succeeds?
Because the database layer permits multi-statement execution, an attacker can use stacked SQL queries for full database read and write access. The described outcome includes administrator account takeover.
Which versions need remediation?
Versions before ILIAS 9.22, 10.10, and 11.3 are affected. Upgrade to the applicable fixed version or a later release.
