Because administrator authentication is cookie-only and no CSRF token is enforced, an unauthenticated attacker can induce a logged-in administrator's browser to issue a forged content-save request with a text payload containing a scripting marker. The marker is stored verbatim into content/content.php; on every subsequent page view evaluate_cmsimple_scripting() (functions.php) executes the marker body with PHP eval() — for all visitors, including unauthenticated ones. This yields persistent remote code execution on the web server.","state":0,"publishedAt":"2026-09-22T00:00:00+00:00","modifiedAt":"2026-09-25T23:25:58.203+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/15536818056/CVE/issues/5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88418","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88418","identifiers":["CVE-2026-88418"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
