When the default blacklist is active (i.e., a self-hosted deployment has not defined BLACKLIST_IPS), an authenticated user with the Builder permission can submit a REST datasource query preview request to POST /api/queries/preview targeting a reachable HTTP(S) service in the 100.64.0.0/10 range, causing the server to send a request to that target and return its response through the preview flow. Per the advisory, no released fix was identified at the time of publication; remediation is to add 100.64.0.0/10 to DEFAULT_BLACKLIST.","evidence":"cve:CVE-2026-82241","products":[{"name":{"value":"server","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-82241","aliases":["CVE-2026-82241"],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":7.1,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"LOW","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"HIGH"}},{"format":"CVSS","cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.1,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","integrityImpact":"LOW","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"budibase","product":"server","versions":[{"status":"affected","version":"0","lessThan":"3.41.3","versionType":"semver"},{"status":"unaffected","version":"3.41.3","versionType":"semver"}],"packageURL":"pkg:npm/%40budibase/server","defaultStatus":"unaffected"}],"modified":"2026-10-08T15:25:24.916Z","provider":"cve","references":["https://github.com/Budibase/budibase/security/advisories/GHSA-9754-4wm6-3c8r","https://www.vulncheck.com/advisories/budibase-backend-core-ssrf-via-incomplete-default-blacklist"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-82241","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-08-28T14:46:47.075515Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-28T14:46:56.389Z"}}],"cna":{"orgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","shortName":"VulnCheck","dateUpdated":"2026-10-08T15:25:24.916Z"}}},"related_cves":[{"value":"CVE-2026-82241","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"},"priority":{"reasons":["publisher_severity"],"severity":"high","linked_cves":[],"fix_available":false,"known_exploited":false,"publisher_severity":"high"},"context_update":false}],"next_after":12908,"next_before":12908}
