CVE intelligence and bounded remediation

CVE-2024-41812 — txtdot is an HTTP proxy that parses only text, links, and pictures from pages, removing ads and heavy scripts

High CVSS 7.5

txtdot is an HTTP proxy that parses only text, links, and pictures from pages, removing ads and heavy scripts. Prior to version 1.7.0, a Server-Side Request Forgery (SSRF) vulnerability in the `/get` route of txtdot allows remote attackers to use the server as a proxy to send HTTP GET requests to arbitrary targets and retrieve information in the internal network. Version 1.7.0 prevents displaying the response of forged requests, but the requests can still be sent. For complete mitigation, a firewall between txtdot and other internal network resources should be set.

Matched remediation archetype

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.
