Title
Axios: HTTP/2 adapter bypasses configured DNS lookup and proxy controls
Summary
Axios is a promise-based HTTP client for the browser and Node.js. From 1.13.0 until 1.20.0, Axios HTTP/2 request setup does not consistently apply proxy settings and caller-supplied DNS lookup policy. An HTTPS request uses httpVersion: 2 with explicit config.proxy or environment-derived proxy settings, or relies on caller-supplied config.lookup DNS policy. The HTTP/2 path can connect without the configured proxy behavior or without applying the caller-supplied config.lookup policy before http2.connect(). Requests can bypass the intended proxy route or the caller-supplied DNS resolution policy. This issue is fixed in version 1.20.0.

Title
OpenClaw Windows Node through 2026.9.4 SSRF via canvas.present
Summary
OpenClaw Windows Node through 2026.9.4 contains a server-side request forgery vulnerability in the canvas.present capability that bypasses URL risk evaluation enforced by canvas.navigate. Attackers with gateway or agent access can issue canvas.present to make the node's WebView send requests to localhost, private networks, or tailnet services from the user's machine.

Title
Server-Side Request Forgery in Wegow PDF export
Summary
Server-Side Request Forgery (SSRF) reported in the ticket sales chart PDF export functionality of Wegow. According to the report, an authenticated user with a promoter account can manipulate the <svg> parameter of the POST request generated by selecting Download PDF. The content is processed by the export.highcharts.com service, which sends HTTP requests to attacker-controlled external resources and embeds their responses in the generated PDF. The reported behavior allows the export service to be used as an intermediary for these requests.

CVE-2026-101087 (GCVE-0-2026-101087)

Vulnerability from cvelistv5 – Published: 2026-09-27 20:49 – Updated: 2026-09-30 14:12

Title
Nezha 2.0.10 through 2.3.2 SSRF Denylist Bypass IPv6
Summary
Nezha versions 2.0.10 through 2.3.2 use a restricted HTTP client to validate user-configurable notification and DDNS webhook URLs, but the denylist did not cover IPv6 transition ranges — specifically the 6to4 prefix 2002::/16 and the local-use IPv4/IPv6 translation prefix 64:ff9b:1::/48. Because such addresses satisfy Go's netip.Addr.IsGlobalUnicast check, the URL validator accepted them. An authenticated user able to configure a webhook may be able to cause the dashboard to issue requests to an otherwise restricted IPv6 endpoint, but only where the dashboard's network provides unusual or non-standards-compliant routing for these transition ranges; no direct path to an IPv4 metadata, loopback, or private-network HTTP request has been demonstrated. The issue is fixed in version 2.3.3 (commit d1fcde8e), which blocks both prefixes.

Title
Obot before v0.23.0 Server-Side Request Forgery via MCP
Summary
Obot before v0.23.0 contains a server-side request forgery vulnerability in remote MCP server registration that allows privileged users to specify arbitrary URLs without destination validation. Attackers with Power User or higher roles can coerce Obot to make requests to internal services and cloud metadata endpoints, reading responses in error messages to disclose sensitive credentials.

Title
utcp-gql and utcp-websocket before 1.1.1 SSRF via URL validation bypass
Summary
utcp-gql before 1.1.1 and utcp-websocket before 1.1.1 contain server-side request forgery vulnerabilities due to incomplete application of CVE-2026-44661 fixes. The GraphQL plugin uses a vulnerable prefix check allowing bypass URLs like http://127.0.0.1.attacker.example, while the WebSocket plugin performs no URL validation despite documented security requirements. Attackers can force connections to internal services and cloud metadata endpoints by supplying malicious tool URLs in call templates, and receive configured API keys and OAuth tokens sent to attacker-controlled hosts.

CVE-2026-101060 (GCVE-0-2026-101060)

Vulnerability from cvelistv5 – Published: 2026-09-27 17:02 – Updated: 2026-09-28 13:11
VLAI
Title
python-utcp before 1.1.4 SSRF via unvalidated HTTP redirects
Summary
python-utcp versions before 1.1.4 contain a server-side request forgery vulnerability in HttpCommunicationProtocol.call_tool that validates the initial tool URL but follows HTTP redirects without re-validating the target. Attackers controlling a tool endpoint can return a 302 redirect to internal services, allowing the UTCP client to reach cloud metadata endpoints or internal HTTP services and return their response bodies to the caller.

CVE-2026-101059 (GCVE-0-2026-101059)

Vulnerability from cvelistv5 – Published: 2026-09-27 17:02 – Updated: 2026-09-28 14:02

Title
utcp-http before 1.1.4 OAuth2 tokenUrl Trust Boundary Bypass
Summary
utcp-http before 1.1.4 fails to validate the OAuth2 tokenUrl field from remote OpenAPI specifications, allowing attackers to redirect credential submission to arbitrary endpoints. When a victim registers an attacker-controlled OpenAPI spec and invokes a generated OAuth2-protected tool, the library POSTs the victim's client_id and client_secret to the attacker-supplied token endpoint without URL validation.

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.
