{"schema":"threatline.record/2","record":{"id":"CVE-2026-104070","aliases":[],"summary":"SPIP Crayons Plugin < 3.5.0 Authorization Bypass RCE","details":"The Crayons plugin for SPIP before 3.5.0 contains a missing authorization vulnerability that allows unauthenticated attackers to modify arbitrary editable object fields by omitting the secu_ anti-forgery parameter in crayons_store.php, causing the authorization dispatcher to resolve an unconditionally-true handler instead of the proper modification check. 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.","categories":["Unclassified"],"product":"SPIP Crayons Plugin","vendor":"SPIP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104070","source_modified_at":"2026-10-09T01:11:15.811Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"SPIP Crayons Plugin","vendor":"SPIP","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"3.5.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104070","source_modified_at":"2026-10-09T01:11:15.811Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"SPIP Crayons Plugin","ecosystem":null},"version":"3.5.0","basis":"first unaffected version stated in the CVE record"}],"cvss":9.3,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00571,"percentile":0.46527,"score_date":"2026-10-23"},"published_at":"2026-10-06T16:16:07.042Z","modified_at":"2026-10-09T01:11:15.811Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104070","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-09T01:11:15.811Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104070","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://blog.spip.net/Mises-a-jour-de-securite-critique-plugins-Crayons-et-Simplog.html?lang=fr","tags":["vendor-advisory","patch"]},{"source":"CVE List","url":"https://plugins.spip.net/crayons.html?lang=fr","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/spip-crayons-plugin-authorization-bypass-rce","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-09T01:11:07.177365Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-09T01:11:15.811Z","content_hash":"cf17b695cc7c2995d466f5b5bc913b6f68204c61c553e35dee11cc9ed80466db"}}
