CVE-2026-42538: Dfir-Iris Iris-Web

Medium severity, CVSS 6.3. EPSS: 0.3% chance of exploitation in the next 30 days.

IRIS is a web collaborative platform that helps incident responders share technical details during investigations. Versions prior to 2.4.28 do not properly validate uploaded files. The application can therefore be misused to host phishing pages, amongst other things. This also creates another instance of a Cross-Site Scripting (XSS) vulnerability. Version 2.4.28 contains a patch.
