When a customer (the lowest-privileged authenticated role) uploads an SSL certificate for one of their own domains, the Certificates API add()/update() methods parse it with openssl_x509_parse() and store the issuer organization (issuer['O']) value verbatim without sanitization. Froxlor's table-listing renderer then emits scalar cells through Twig's `raw` filter, disabling HTML auto-escaping, so when an administrator or reseller opens Domains > SSL certificates the attacker-supplied issuer value executes as script in the privileged user's session. This crosses a privilege boundary from customer to admin and can result in full administrator account takeover; because a Froxlor admin controls webserver, DNS, and PHP configuration applied by a cron job running as root, the issue can be further escalated to command execution as root on the managed server. The issue is fixed in Froxlor 2.3.12.","state":0,"publishedAt":"2026-09-26T13:24:10.569+00:00","modifiedAt":"2026-09-26T23:02:23.814+00:00","affected":[{"ecosystem":"Vendor product","name":"froxlor","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"froxlor\",\n                    \"product\": \"froxlor\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"2.0.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.3.12\"\n                        },\n                        {\n                            \"version\": \"2.3.12\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/froxlor/froxlor/security/advisories/GHSA-89vj-gqqr-73p8","https://www.vulncheck.com/advisories/froxlor-before-2.3.12-stored-xss-via-ssl-certificate-issuer"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100720","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100720","identifiers":["CVE-2026-100720"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
