An attacker who can authenticate to the administration interface can submit a specially crafted value for the Name field.

Once an attacker injects a payload, any visitor to the page that displays the category name can run the code, potentially leading to data theft or defacement."}}}}, "created": "2026-04-06T21:47:42.912400+00:00", "updated": "2026-04-08T19:52:51.191307+00:00", "vendors": ["feehi", "feehi$PRODUCT$feehi_cms"]}
