Prior to 3.39.4, uploadUrl in packages/server/src/utilities/fileUtils.ts used a bare server-side fetch for string attachment values passed by processAttachments in packages/server/src/sdk/workspace/ai/helpers/rows.ts. A builder with the AI table-generation feature could cause an attachment value to reference an internal service or cloud metadata endpoint, and the response would be stored as an attachment without fetchWithBlacklist validation. This issue is fixed in version 3.39.4.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N","score":4.9},"cvss_v3":null,"cwes":["CWE-918"],"references":["https://github.com/Budibase/budibase/commit/fc8161e739bdc5513c4314282251e327e7fe339f","https://github.com/Budibase/budibase/pull/18866","https://github.com/Budibase/budibase/releases/tag/3.39.4","https://github.com/Budibase/budibase/security/advisories/GHSA-hfhx-w8p8-4hc7","https://github.com/Budibase/budibase/security/advisories/GHSA-hfhx-w8p8-4hc7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-73307","score":0.00427,"percentile":0.37023,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-hfhx-w8p8-4hc7","url":"https://osv.dev/vulnerability/GHSA-hfhx-w8p8-4hc7","summary":"Budibase: SSRF via bare fetch() in uploadUrl during AI table generation","modified":"2026-08-12T19:26:07.520072Z","packages":[{"ecosystem":"npm","name":"@budibase/server","purl":"pkg:npm/%40budibase/server","ranges":["<=3.38.1"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
