What is CVE-2026-82243?

Budibase Server before version 3.41.3 is vulnerable to a server-side request forgery (SSRF) that allows builder-level users to bypass SSRF validation on the datasource verify endpoint. This flaw enables attackers to submit arbitrary URLs, potentially leading to the exposure of sensitive internal CouchDB credentials. By exploiting this vulnerability, attackers controlling these URLs can gain unauthorized access to the database, posing a significant risk in cloud deployments.
