What an attacker can do

The source says the flaw enables blind write-only cross-site request forgery using the victim's cookies against ActionHandler.handle and PagesHandler.handleWithErrorFallback when manifest.checkOrigin is enabled; the attacker can trigger a state-mutating action or endpoint handler but cannot read the cross-origin response. Vendor/CNA’s CVSS 4.0 assessment (base score 5.1/10) rates confidentiality, integrity and availability impact as none.
