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.","categories":["Unclassified"],"product":"eventschedule","vendor":"eventschedule","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55190","source_modified_at":"2026-10-23T12:24:27.295Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"eventschedule","vendor":"eventschedule","versions":[{"status":"affected","version":"<= 1.0.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/eventschedule/eventschedule/security/advisories/GHSA-664j-55hw-p8fm","source_modified_at":"2026-06-17T11:08:43Z","fetched_at":"2026-10-23T18:55:00.935475Z","package":{"ecosystem":"other","name":"eventschedule"},"range":"<= 1.0.0"}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00361,"percentile":0.2878,"score_date":"2026-10-24"},"published_at":"2026-10-23T12:24:27.295Z","modified_at":"2026-10-23T12:24:27.295Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55190","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:24:27.295Z"},{"source":"GitHub Advisory Database","url":"https://github.com/eventschedule/eventschedule/security/advisories/GHSA-664j-55hw-p8fm","fetched_at":"2026-10-23T18:55:00.935475Z","source_modified_at":"2026-06-17T11:08:43Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55190","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-10-24"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eventschedule/eventschedule/security/advisories/GHSA-664j-55hw-p8fm","tags":["x_refsource_CONFIRM"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T12:24:27.295Z","content_hash":"01d83ce6ac2c4f2b4422273ca388fe5a686529a26108ffb4036732c26809f1b2"}}
