Description
MindsDB versions up to 26.1.0 have a server-side request forgery (SSRF) vulnerability in the web crawler handler. This flaw allows unauthenticated attackers to supply arbitrary URLs to the CrawlerTable.list function, enabling them to fetch internal resources. The vulnerability arises because the default configuration has an empty allowlist, which attackers can exploit to bypass restrictions and access internal services and cloud metadata endpoints without authentication.

Technical Analysis
MindsDB through version 26.1.0 contains a server-side request forgery vulnerability (CWE-918) in its web crawler handler. Unauthenticated attackers can supply arbitrary URLs to the CrawlerTable.list function, which fetches these URLs on the server side. Due to the default empty allowlist configuration, attackers can bypass intended access controls and retrieve data from internal services and cloud metadata endpoints. This vulnerability has a CVSS 3.1 base score of 7.5, indicating high severity. There are no known exploits in the wild and no patch or remediation information is currently provided.
Potential Impact
An unauthenticated attacker can exploit this SSRF vulnerability to access internal network resources and cloud metadata endpoints that should be protected. This can lead to unauthorized disclosure of sensitive information. The vulnerability does not impact integrity or availability directly but has a high confidentiality impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, review and configure the allowlist for the web crawler handler to restrict accessible URLs and prevent unauthorized internal resource access.
