CVE-2026-31829 (GCVE-0-2026-31829)

Title
Flowise affected by Server-Side Request Forgery (SSRF) in HTTP Node Leading to Internal Network Access
Summary
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.0.13, Flowise exposes an HTTP Node in AgentFlow and Chatflow that performs server-side HTTP requests using user-controlled URLs. By default, there are no restrictions on target hosts, including private/internal IP ranges (RFC 1918), localhost, or cloud metadata endpoints. This enables Server-Side Request Forgery (SSRF), allowing any user interacting with a publicly exposed chatflow to force the Flowise server to make requests to internal network resources that are inaccessible from the public internet. This vulnerability is fixed in 3.0.13.

CVE-2026-31818 (GCVE-0-2026-31818)

Vulnerability from cvelistv5 – Published: 2026-04-03 15:41 – Updated: 2026-04-03 20:04

Title
Budibase: Server-Side Request Forgery via REST Connector with Empty Default Blacklist
Summary
Budibase is an open-source low-code platform. Prior to version 3.33.4, a server-side request forgery (SSRF) vulnerability exists in Budibase's REST datasource connector. The platform's SSRF protection mechanism (IP blacklist) is rendered completely ineffective because the BLACKLIST_IPS environment variable is not set by default in any of the official deployment configurations. When this variable is empty, the blacklist function unconditionally returns false, allowing all requests through without restriction. This issue has been patched in version 3.33.4.

Title
Tautulli: Unauthenticated pms_image_proxy endpoint proxies arbitrary HTTP requests through the Plex Media Server
Summary
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the /pms_image_proxy endpoint accepts a user-supplied img parameter and forwards it to Plex Media Server's /photo/:/ transcode transcoder without authentication and without restricting the scheme or host. The endpoint is intentionally excluded from all authentication checks in webstart.py, any value of img beginning with http is passed directly to Plex, this causes the Plex Media Server process, which typically runs on the same host or internal network as Tautulli, with access to RFC-1918 address space, to issue an outbound HTTP request to any attacker-specified URL. This issue has been patched in version 2.17.0.

Title
LinkAce affected by SSRF via link creation: NoPrivateIpRule not applied to LinkStoreRequest
Summary
LinkAce is a self-hosted archive to collect website links. When a user creates a link via POST /links, the server fetches HTML metadata from the provided URL (LinkRepository::create() calls HtmlMeta::getFromUrl()). The LinkStoreRequest validation rules do not include NoPrivateIpRule, allowing server-side requests to internal network addresses, Docker service hostnames, and cloud metadata endpoints. The project already has a NoPrivateIpRule class (app/Rules/NoPrivateIpRule.php) but it is only applied in FetchController.php (line 99), not in the primary link creation path.

Title
WeKnora: DNS Rebinding Vulnerability in web_fetch Tool Allows SSRF to Internal Resources
Summary
WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.3.0, a DNS rebinding vulnerability in the web_fetch tool allows an unauthenticated attacker to bypass URL validation and access internal resources on the server, including private IP addresses (e.g., 127.0.0.1, 192.168.x.x). By crafting a malicious domain that resolves to a public IP during validation and subsequently resolves to a private IP during execution, an attacker can access sensitive local services and potentially exfiltrate data. This issue has been patched in version 0.3.0.

Title
Wekan Vulnerable to SSRF through Lack of Validation or Filtering in Attachment URL Loading
Summary
Wekan is an open source kanban tool built with Meteor. Versions 8.32 and 8.33 are vulnerable to Server-Side Request Forgery (SSRF) via attachment URL loading. During board import in Wekan, attachment URLs from user-supplied JSON data are fetched directly by the server without any URL validation or filtering, affecting both the Wekan and Trello import flows. The parseActivities() and parseActions() methods extract user-controlled attachment URLs, which are then passed directly to Attachments.load() for download with no sanitization. This Server-Side Request Forgery (SSRF) vulnerability allows any authenticated user to make the server issue arbitrary HTTP requests, potentially accessing internal network services such as cloud instance metadata endpoints (exposing IAM credentials), internal databases, and admin panels that are otherwise unreachable from outside the network. This issue has been fixed in version 8.34.

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.
