Attackers can bypass template-level authorization guards through direct HTTP requests to invoke actions such as editer_auteur, enabling arbitrary account password rewrites including administrator accounts and resulting in full account takeover.","state":0,"publishedAt":"2026-09-11T16:38:18.595+00:00","modifiedAt":"2026-10-01T15:20:27.422+00:00","affected":[{"ecosystem":"Vendor product","name":"SPIP","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"SPIP\",\n                    \"product\": \"SPIP\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"4.4.18\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://blog.lexfo.fr/casse-spip-sqli-to-rce.html","https://blog.spip.net/Mise-a-jour-critique-de-securite-sortie-de-SPIP-4-4-18.html","https://www.vulncheck.com/advisories/spip-missing-authorization-via-ecrire-action-editer-auteur"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72709","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72709","identifiers":["CVE-2026-72709"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
