Attackers can chain this flaw to write a malicious .html skeleton file, disclose sensitive configuration files containing the site secret, and forge a signed ajax context to execute the uploaded skeleton, achieving arbitrary PHP code execution as the web-server user.","state":0,"publishedAt":"2026-10-06T16:16:07.042+00:00","modifiedAt":"2026-10-09T01:11:15.811+00:00","affected":[{"ecosystem":"Vendor product","name":"SPIP Crayons Plugin","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"SPIP\",\n                    \"product\": \"SPIP Crayons Plugin\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.5.0\"\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.spip.net/Mises-a-jour-de-securite-critique-plugins-Crayons-et-Simplog.html?lang=fr","https://plugins.spip.net/crayons.html?lang=fr","https://www.vulncheck.com/advisories/spip-crayons-plugin-authorization-bypass-rce"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104070","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104070","identifiers":["CVE-2026-104070"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
