{"apiVersion":"1.0","identifier":"CVE-2026-73407","description":"Budibase is an open-source low-code platform. Prior to 3.40.1, RestIntegration._req in packages/server/src/integrations/rest.ts attached credentials from getAuthHeaders and defaultHeaders without requiring the final request destination to match the datasource origin. An unauthenticated caller of a PUBLIC POST /api/v2/queries/:queryId query could supply an absolute or parameterized path to an attacker-controlled host and receive the stored bearer, basic, or static-header credentials. This issue is fixed in version 3.40.1.","publishedAt":"2026-08-12T20:17:55","lastModifiedAt":"2026-08-12T20:17:55","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73407","cvssScore":9,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00422,"riskScore":0.93,"affectedProduct":"Budibase","affectedVersions":"<3.40.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73407","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73407","en":"https://www.redsauce.net/en/cves/CVE-2026-73407","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73407","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73407","de":"https://www.redsauce.net/de/cves/CVE-2026-73407","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73407","el":"https://www.redsauce.net/el/cves/CVE-2026-73407"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73407"}}
