Title
Dradis Community Edition 5.1.0 through 5.2.0 Server-Side Request Forgery via Unrestricted AI Provider Address
Summary
In Dradis Community Edition, the ProvidersController and AgentsController gate their admin_required before_action on `defined?(Dradis::Pro)`, a constant that is never defined in CE, so the authorization check is never applied. As a result, any authenticated (non-admin) user can create an AI provider pointing to an arbitrary HTTP/HTTPS address (including internal/link-local hosts such as http://169.254.169.254) and reassign the built-in Roslin agent to use it. When an AI interaction is triggered, the server issues a request to the attacker-supplied URL (server-side request forgery). For non-2xx responses, the target's response body is reflected verbatim to the attacker's browser via ActionCable/Turbo Stream error messages, making the SSRF readable.

Title
MCPHub: SSRF Guard Bypass via IPv6 Transition Addresses in URL Validation
Summary
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.32, MCPHub's SSRF guard in src/utils/ssrf.ts uses a custom isBlockedIpv6 function that only checks for loopback, link-local, unique-local, IPv4-mapped, and IPv4-compatible IPv6 addresses. IPv6 transition address families -- NAT64 (64:ff9b::/96), 6to4 (2002::/16), and Teredo (2001::/32) -- are not checked. An attacker who can specify a URL for an MCP server connection can encode a private IPv4 address inside one of these IPv6 forms to bypass the SSRF guard and reach internal infrastructure. This issue has been patched in version 1.0.32.

Title
MCPHub vulnerable to SSRF: a non-admin user can make mcphub request arbitrary URLs and read the response (OpenAPI proxy + transport dial)
Summary
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.32, an authenticated non-admin user can register a server pointing at an arbitrary URL and make the hub issue server-side requests to it, with no egress filtering (no block of loopback / RFC1918 / link-local 169.254.0.0/16). Via the OpenAPI proxy path the response body is returned to the caller (full, reflected SSRF); via the SSE/streamable-http transport the request is sent blind. This issue has been patched in version 1.0.32.

Title
Galaxy_ng: galaxy_ng: blind ssrf via namespace avatar_url with no private-address restriction
Summary
A server-side request forgery (SSRF) vulnerability was found in galaxy_ng, the Ansible Galaxy server plugin for Pulp. An authenticated user with namespace management permissions can set a namespace avatar URL to an arbitrary address, including internal networks, loopback, or cloud instance metadata endpoints. A background worker fetches that URL without checking the destination, which lets the attacker probe internal services and enumerate reachable IP addresses. The HTTP client is also configured without an overall timeout, so a slow or non-responsive target can pin workers and cause a denial of service.

Title
Ech0 before 4.4.3 SSRF via DNS Resolution Bypass
Summary
Ech0 before 4.4.3 contains a server-side request forgery vulnerability in the validateWebhookURL function (webhook_setting_service.go), which only validates literal IP addresses via net.ParseIP() and fails to reject hostnames that DNS-resolve to private or internal IPs (e.g., 169.254.169.254.nip.io). An attacker with admin privileges can create a webhook with such a hostname to bypass validation and cause the server to make requests to internal services, cloud metadata endpoints, and private network resources. The issue is fixed in 4.4.3.

Title
Ech0 before 4.7.3 Server-Side Request Forgery via fetchPeerConnectInfo
Summary
Ech0 before 4.7.3 contains a server-side request forgery vulnerability in the fetchPeerConnectInfo function that uses unvalidated HTTP requests instead of safe request methods with URL validation. Authenticated attackers can supply arbitrary URLs to access internal services and cloud metadata endpoints by triggering connection health checks or peer connection operations.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
