In versions 1.0.0 and prior, App\\Utils\\UrlUtils::isUrlSafe() is the SSRF guard applied to user-supplied import URLs. It can be bypassed two ways, both reaching internal/localhost services when the URL is later fetched by ImportCuratorEvents (Http::get($url) then the response body is parsed and imported as events, and file_get_contents($ogImage)). At time of publication, there are no publicly available patches.","state":0,"publishedAt":"2026-10-23T12:24:27.295+00:00","modifiedAt":"2026-10-23T12:24:27.295+00:00","affected":[{"ecosystem":"Vendor product","name":"eventschedule","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"eventschedule\",\n                    \"product\": \"eventschedule\",\n                    \"versions\": [\n                        {\n                            \"version\": \"<= 1.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/eventschedule/eventschedule/security/advisories/GHSA-664j-55hw-p8fm"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55190","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55190","identifiers":["CVE-2026-55190"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
