Successful exploitation allows the attacker to read filter-rule metadata and to add, change, or delete rules outside their authorized organization. Those changes persist in the live filter configuration and can affect the content included in a subsequent Content View publication. Already-published Content View versions are immutable snapshots and are not modified by this flaw.\nConfidentiality is Low because the disclosed data is filter-rule metadata rather than repository contents or credentials. Integrity is Low because the attacker can modify unpublished filter rules, but cannot publish or promote Content Views, cannot alter already-published versions, and cannot change repository content or host state.", "threat_severity": "Moderate"}
