Project: Islandora [1] Date: 2026-February-25 Security risk: *Moderately critical* 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Arbitrary file upload, Cross-site scripting

Affected versions: <2.17.5 CVE IDs: CVE-2026-3215 Description:  This module integrates with Islandora, an open-source digital asset management (DAM) framework. Islandora integrates with various open-source services, which can be run in a distributed environment.

The module doesn't sufficiently sanitize URI paths for its custom route used for attaching media to nodes, which can also lead to cross-site scripting and other vulnerabilities.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "create media" and the ability to edit the node the media is being attached to.

Solution:  Install the latest version:

* If you use the Islandora module, upgrade to Islandora 2.17.5 [3].
