{"schema":"threatline.record/2","record":{"id":"CVE-2026-109431","aliases":[],"summary":"Camunda Missing Authorization in Task Sub-Resources","details":"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.","categories":["Unclassified"],"product":"Camunda 7","vendor":"Camunda","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109431","source_modified_at":"2026-10-19T17:41:49.520Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Camunda 7","vendor":"Camunda","versions":[{"status":"affected","version":"7.24.0","versionType":"semver","lessThan":"7.24.14"},{"status":"affected","version":"7.23.0","versionType":"semver","lessThan":"7.23.17"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109431","source_modified_at":"2026-10-19T17:41:49.520Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Camunda 7","ecosystem":null},"version":"7.24.14","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109431","source_modified_at":"2026-10-19T17:41:49.520Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Camunda 7","ecosystem":null},"version":"7.23.17","basis":"first unaffected version stated in the CVE record"}],"cvss":8.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00359,"percentile":0.28516,"score_date":"2026-10-23"},"published_at":"2026-10-19T15:06:00.780Z","modified_at":"2026-10-19T17:41:49.520Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109431","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T17:41:49.520Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109431","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://codeant.ai/security-research/camunda-task-attachment-authorization-cve-2026-109431","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://docs.camunda.org/enterprise/download/","tags":["product","patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/camunda-missing-authorization-in-task-sub-resources","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-19T17:41:31.091455Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T17:41:49.520Z","content_hash":"ab785ef81009230a33242ae5bfce3c9a826d454e22461a11a5e1f14d1d1c60dc"}}
