Description (CNA)
Camunda 7.24.0 before 7.24.14 and 7.23.0 before 7.23.17 contains a missing authorization check vulnerability in engine-rest task sub-resources that allows authenticated attackers with no permission grants to access task comments and attachments by calling singular read and delete endpoints that lack the authorization-filtered checks enforced on their corresponding list endpoints. Attackers can exploit TaskAttachmentResourceImpl and TaskCommentResourceImpl methods such as getAttachment, getAttachmentData, deleteAttachment, and getComment using only a known object ID to read, download, or permanently delete task attachments and comments.
