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.","state":0,"publishedAt":"2026-10-19T15:06:00.78+00:00","modifiedAt":"2026-10-19T17:41:49.52+00:00","affected":[{"ecosystem":"Vendor product","name":"Camunda 7","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Camunda\",\n                    \"product\": \"Camunda 7\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.24.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"7.24.14\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.23.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"7.23.17\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1,"severity":"HIGH"}],"references":["https://codeant.ai/security-research/camunda-task-attachment-authorization-cve-2026-109431","https://docs.camunda.org/enterprise/download/","https://www.vulncheck.com/advisories/camunda-missing-authorization-in-task-sub-resources"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109431","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109431","identifiers":["CVE-2026-109431"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
