CVE-2024-4084 — Mintplexlabs Anythingllm security vulnerability

High CVSS 7.7

A Server-Side Request Forgery (SSRF) vulnerability exists in the latest version of mintplex-labs/anything-llm, allowing attackers to bypass the official fix intended to restrict access to intranet IP addresses and protocols. Despite efforts to filter out intranet IP addresses starting with 192, 172, 10, and 127 through regular expressions and limit access protocols to HTTP and HTTPS, attackers can still bypass these restrictions using alternative representations of IP addresses and accessing other ports running on localhost. This vulnerability enables attackers to access any asset on the internal network, attack web services on the internal network, scan hosts on the internal network, and potentially access AWS metadata endpoints. The vulnerability is due to insufficient validation of user-supplied URLs, which can be exploited to perform SSRF attacks.

Server-side request forgery and unintended proxying

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
