{"id":"DEBIAN-CVE-2026-72709","details":"SPIP before version 4.4.18 contains a missing authorization vulnerability in sensitive actions under ecrire/action/ that allows unauthenticated attackers to invoke privileged actions by supplying only a valid CSRF nonce without any server-side permission check. 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.","modified":"2026-09-15T08:47:49.756810605Z","published":"2026-09-11T17:18:58.760Z","upstream":["CVE-2026-72709"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-72709"}],"affected":[{"package":{"name":"spip","ecosystem":"Debian:13","purl":"pkg:deb/debian/spip?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.4.19+dfsg-0+deb13u1"}]}],"versions":["4.4.10+dfsg-1","4.4.11+dfsg-0+deb13u1","4.4.11+dfsg-1","4.4.13+dfsg-0+deb13u1","4.4.13+dfsg-1","4.4.14+dfsg-1","4.4.15+dfsg-0+deb13u1","4.4.15+dfsg-1","4.4.16+dfsg-0+deb13u1","4.4.16+dfsg-1","4.4.18+dfsg-1","4.4.3+dfsg-1","4.4.3+dfsg-1+deb13u1","4.4.4+dfsg-1","4.4.5+dfsg-1","4.4.6+dfsg-1","4.4.7+dfsg-1","4.4.8+dfsg-1","4.4.9+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-72709.json"}},{"package":{"name":"spip","ecosystem":"Debian:14","purl":"pkg:deb/debian/spip?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.4.18+dfsg-1"}]}],"versions":["4.4.10+dfsg-1","4.4.11+dfsg-1","4.4.13+dfsg-1","4.4.14+dfsg-1","4.4.15+dfsg-1","4.4.16+dfsg-1","4.4.3+dfsg-1","4.4.4+dfsg-1","4.4.5+dfsg-1","4.4.6+dfsg-1","4.4.7+dfsg-1","4.4.8+dfsg-1","4.4.9+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-72709.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
