{"apiVersion":"1.0","identifier":"CVE-2026-81335","description":"Baserow dispatches an Application Builder data source without acting on the result of its permission check. The dispatch and record-name views in backend/src/baserow/contrib/builder/api/data_sources/views.py are declared with a permission class that admits any caller, so a request carrying no credential reaches the handler. DataSourceService.dispatch_data_sources in backend/src/baserow/contrib/builder/data_sources/service.py then calls check_multiple_permissions without asking it to raise, and neither stores nor examines the mapping of denials it returns, so a denied check leaves execution to continue and the data source is dispatched whatever the caller-s identity. The dispatch runs with the integration-s own credentials, so an unauthenticated request naming a data source receives the rows and fields that source reads. Identifiers are small integers and can be enumerated. Version 2.3.1 passes raise_exception to the same call.","publishedAt":"2026-08-27T17:20:53","lastModifiedAt":"2026-08-27T20:18:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81335","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00421,"riskScore":0.78,"affectedProduct":"baserow","affectedVersions":"<2.3.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81335","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81335","en":"https://www.redsauce.net/en/cves/CVE-2026-81335","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81335","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81335","de":"https://www.redsauce.net/de/cves/CVE-2026-81335","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81335","el":"https://www.redsauce.net/el/cves/CVE-2026-81335"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81335"}}
