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.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://codeant.ai/security-research/camunda-task-attachment-authorization-cve-2026-109431","tags":[]},{"url":"https://docs.camunda.org/enterprise/download/","tags":[]},{"url":"https://www.vulncheck.com/advisories/camunda-missing-authorization-in-task-sub-resources","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
