CVE-2025-57055 — WonderCMS 3.5.0 is vulnerable to Server-Side Request Forgery (SSRF) in the custom module installation functionality

Medium CVSS 6.5

WonderCMS 3.5.0 is vulnerable to Server-Side Request Forgery (SSRF) in the custom module installation functionality. An authenticated administrator can supply a malicious URL via the pluginThemeUrl POST parameter. The server fetches the provided URL using curl_exec() without sufficient validation, allowing the attacker to force internal or external HTTP requests.

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.
