CVE-2026-2711 is a server-side request forgery vulnerability affecting the worldquant-miner software developed by zhutoutoutousan, specifically versions 1.0.0 through 1.0.9. The flaw resides in an unspecified function within the URL handler component, located in the file worldquant-miner-master/agent-dify-api/core/helper/ssrf_proxy.py. The vulnerability arises from improper validation or sanitization of the make_request argument, allowing an attacker to coerce the server into making arbitrary HTTP requests to internal or external systems. This SSRF can be triggered remotely without requiring authentication or user interaction, but the attack complexity is high and exploitation is difficult, likely due to environmental or input constraints. The vulnerability was responsibly disclosed but remains unpatched as of the publication date. The CVSS 4.0 vector indicates network attack vector, high attack complexity, no privileges or user interaction needed, and low impact on confidentiality, integrity, and availability. No known exploits are currently active in the wild. The vulnerability could potentially be leveraged to access internal services, perform reconnaissance, or facilitate further attacks depending on the server's network environment and access controls.

The primary impact of CVE-2026-2711 is the potential for attackers to perform unauthorized server-side requests, which can lead to information disclosure or interaction with internal systems not normally accessible externally. This could enable attackers to bypass network segmentation, access sensitive internal resources, or pivot to other parts of the network. However, the medium CVSS score and low impact ratings suggest that direct confidentiality, integrity, or availability damage is limited without additional chained exploits. The high complexity and difficulty of exploitation reduce the likelihood of widespread attacks, but targeted attacks against organizations using worldquant-miner could still pose a risk. The lack of vendor response and patches increases exposure time, potentially inviting more sophisticated attackers to develop exploits. Organizations relying on this software in critical environments may face increased risk of reconnaissance and lateral movement attempts.

Given the absence of an official patch, organizations should implement compensating controls to mitigate this SSRF vulnerability. First, restrict outbound HTTP requests from the worldquant-miner server using network-level controls such as firewall rules or proxy filtering to limit the server's ability to reach unauthorized internal or external endpoints. Second, employ strict input validation and sanitization on any user-controllable parameters interacting with the make_request function if source code modifications are possible. Third, monitor logs for unusual outbound request patterns indicative of SSRF exploitation attempts. Fourth, isolate the worldquant-miner service within a segmented network zone with minimal access to sensitive internal resources. Finally, maintain vigilance for vendor updates or community patches and apply them promptly once available. Organizations should also conduct security assessments to identify any potential chained vulnerabilities that could amplify the impact of this SSRF.
