Because task identifiers are sequential integers shared across the entire instance, any authenticated user who is a member of at least one project can enumerate and move (corrupt/hide) tasks belonging to any other project on the same instance, including private projects they have no membership or role on.","state":0,"publishedAt":"2026-07-15T17:03:17.834+00:00","modifiedAt":"2026-10-29T21:16:02.22+00:00","affected":[{"ecosystem":"Vendor product","name":"kanboard","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"kanboard\",\n                    \"product\": \"kanboard\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:github/kanboard/kanboard\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.2.53\"\n                        },\n                        {\n                            \"version\": \"1.2.53\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"564cc30e1e360959572e01e158734d9475c05903\",\n                            \"versionType\": \"git\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/kanboard/kanboard\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.2,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/kanboard/kanboard/issues/5852","https://github.com/kanboard/kanboard/pull/5853","https://github.com/kanboard/kanboard/commit/564cc30e1e360959572e01e158734d9475c05903","https://www.vulncheck.com/advisories/kanboard-boardajaxcontroller-missing-ownership-check-via-drag-and-drop"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-58660","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-58660","identifiers":["CVE-2026-58660"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
