CVE-2026-81207 (GCVE-0-2026-81207)

Vulnerability from cvelistv5 – Published: 2026-09-10 21:35 – Updated: 2026-09-11 13:46
VLAI
Title
DataStage on Cloud Pak for Data has several vulnerabilities due to open source software
Summary
IBM DataStage on Cloud Pak for Data 5.4.0.0 allows any authenticated tenant — with no project membership or role — fully controls scheme/host/port/path of an outbound fetch originating from a shared-infrastructure pod, and the WSDL body is reflected verbatim to the caller. The ds-canvas pod sits on the OpenShift overlay with reach to co-tenant services, in-cluster CP4D APIs, and link-local addresses. Scope is Changed, confidentiality High (response-reflecting), integrity Low (GET-only side-effects).

CVE-2026-81190 (GCVE-0-2026-81190)

Vulnerability from cvelistv5 – Published: 2026-11-05 20:52 – Updated: 2026-11-09 18:38

Title
KurrentDB: Privileged access to read $all enables arbitrary file read and GET-only SSRF
Summary
KurrentDB is a database engineered for modern software applications and event-driven architectures. In version 26.1.0, a user authorized to read the $all stream can use Secondary Indexing query capabilities to read arbitrary files accessible to the database process, enumerate directories, and issue HTTP GET requests from that process. The default configuration limits this privilege to administrators. The flaw does not permit file writes and does not expose environment variables. This issue is fixed in version 26.1.1.
Severity
6.9 (Medium)

Title
Apify Actors MCP Server before 0.9.12 Server-Side Request Forgery via get-html-skeleton
Summary
The get-html-skeleton tool fetched a URL the caller supplied after checking only its syntax. The handler in src/tools/common/get_html_skeleton.ts validated the url argument with isValidHttpUrl from src/utils/generic.ts, which confirmed the string began with an http or https scheme and parsed as a URL and inspected neither the host name nor the address it resolves to. Loopback, link-local and private ranges therefore passed, including the address cloud providers use to serve instance metadata. The unchecked URL was handed to the web-browser actor and the fetched document was returned in the tool response, so any caller of the MCP server could make it request an endpoint reachable only from the host and read the result, including instance credentials. Version 0.9.12 removes the tool.

Title
mcp-use Inspector Proxy Server-Side Request Forgery via Caller-Supplied Target URL
Summary
The proxy middleware in mcp-use's inspector forwards requests to a destination the caller names. mountMcpProxy in libraries/typescript/packages/inspector/src/server/proxy/mcp-proxy.ts read the target from the X-Target-URL header or the __mcp_target parameter and proxied to it without inspecting the host, so loopback, link-local and private addresses were all accepted, as were names that resolve to them, and the validation was not reapplied to a redirect the destination returned. A caller could therefore make the server issue requests to addresses reachable only from the host it runs on and read the responses. The current code calls isSafeProxyTarget, which checks the resolved address against private, loopback and link-local ranges before proxying and bounds the number of redirects followed.

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.
