CVE-2026-86173 Details
Description
MindsDB through 26.1.0 contains a server-side request forgery vulnerability in the web crawler handler that allows unauthenticated attackers to fetch arbitrary URLs by supplying caller-controlled URLs to CrawlerTable.list. Attackers can bypass the allowlist control by exploiting the default empty configuration and access internal services and cloud metadata endpoints without authentication.
A server-side request forgery (SSRF) vulnerability has been identified in MindsDB versions through 26.1.0, specifically within the web crawler handler. This vulnerability allows unauthenticated attackers to fetch arbitrary URLs by supplying caller-controlled URLs to the 'CrawlerTable.list' method. The default empty configuration leaves the allowlist control ineffective, enabling access to internal services and cloud metadata endpoints without authentication. The vulnerability arises because the web crawler can be reached via the unauthenticated HTTP API, which binds to all interfaces in Docker by default.
To address this vulnerability, MindsDB should implement checks in the 'CrawlerTable.list' method to reject URLs that resolve to loopback, link-local, private, or reserved IP ranges. Additionally, the default allowlist should be set to a non-empty, safe configuration.
