CVE-2026-48538

GFI Archiver before 15.13 contains a stored cross-site scripting vulnerability in the default import settings configuration that allows authenticated attackers to inject arbitrary web script or HTML via the configured folders parameter to /Archiver/ImportSettingsWizard.ashx. The injected payload is stored by ImportSettingsWizard.SaveAllConfigSettings() without output encoding and is executed in the browsers of users who subsequently view the Archive Assistant default import settings.
