CVE の説明

Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, under certain conditions, Zammad's verification of inbound PGP-signed email can mark a message as carrying a valid ("Good") PGP signature from a registered sender key, even though the displayed message content is not actually covered by that signature. As a result, the inbound article may be stored with a successful signature status that does not reflect the authenticity of the shown content. This can mislead agents who rely on the signature indicator when assessing the trustworthiness of incoming mail. This issue is fixed in version 7.1.2.
