CVE-2024-32964 WRITEUP CRITICAL WRITEUP
lobehub/lobe_chat < 0.150.6 - Unauthenticated Server-Side Request Forgery via /api/proxy Endpoint
Lobe Chat is a chatbot framework that supports speech synthesis, multimodal, and extensible Function Call plugin system. Prior to 0.150.6, lobe-chat had an unauthorized Server-Side Request Forgery vulnerability in the /api/proxy endpoint. An attacker can construct malicious requests to cause Server-Side Request Forgery without logging in, attack intranet services, and leak sensitive information.

CVE-2024-47066 WRITEUP CRITICAL WRITEUP
lobehub/lobe_chat < 1.19.13 - Server-Side Request Forgery via Redirect Bypass
Lobe Chat is an open-source artificial intelligence chat framework. Prior to version 1.19.13, server-side request forgery protection implemented in `src/app/api/proxy/route.ts` does not consider redirect and could be bypassed when attacker provides an external malicious URL which redirects to internal resources like a private network or loopback address. Version 1.19.13 contains an improved fix for the issue.

CVE-2026-39411 WRITEUP MEDIUM WRITEUP
LobeHub <2.1.48 webapi Routes - Authentication Bypass
LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, the webapi authentication layer trusts a client-controlled X-lobe-chat-auth header that is only XOR-obfuscated, not signed or otherwise authenticated. Because the XOR key is hardcoded in the repository, an attacker can forge arbitrary auth payloads and bypass authentication on protected webapi routes. Affected routes include /webapi/chat/[provider], /webapi/models/[provider], /webapi/models/[provider]/pull, and /webapi/create-image/comfyui. This vulnerability is fixed in 2.1.48.

CVE-2024-24566 WRITEUP MEDIUM WRITEUP
lobehub/lobe_chat < 0.122.4 - Unauthenticated Plugin Access via Improper Access Control
Lobe Chat is a chatbot framework that supports speech synthesis, multimodal, and extensible Function Call plugin system. When the application is password-protected (deployed with the `ACCESS_CODE` option), it is possible to access plugins without proper authorization (without password). This vulnerability is patched in 0.122.4.
CVSS 5.3
CVE-2024-32965 WRITEUP HIGH WRITEUP
lobehub/lobe_chat < 1.19.13 - Unauthenticated Server-Side Request Forgery via JWT Token Header
Lobe Chat is an open-source, AI chat framework. Versions of lobe-chat prior to 1.19.13 have an unauthorized ssrf vulnerability. An attacker can construct malicious requests to cause SSRF without logging in, attack intranet services, and leak sensitive information. The jwt token header X-Lobe-Chat-Auth strored proxy address and OpenAI API Key, can be modified to scan an internal network in the target lobe-web environment. This issue has been addressed in release version 1.19.13 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 8.1
CVE-2025-59417 WRITEUP MEDIUM WRITEUP
lobehub/lobe_chat < 1.129.4 - Cross-Site Scripting via SVG Rendering
Lobe Chat is an open-source artificial intelligence chat framework. Prior to version 1.129.4, there is a a cross-site scripting (XSS) vulnerability when handling chat message in lobe-chat that can be escalated to remote code execution on the user’s machine. In lobe-chat, when the response from the server is like <lobeArtifact identifier="ai-new-interpretation" ...> , it will be rendered with the lobeArtifact node, instead of the plain text. However, when the type of the lobeArtifact is image/svg+xml , it will be rendered as the SVGRender component, which internally uses dangerouslySetInnerHTML to set the content of the svg, resulting in XSS attack. Any party capable of injecting content into chat messages, such as hosting a malicious page for prompt injection, operating a compromised MCP server, or leveraging tool integrations, can exploit this vulnerability. This vulnerability is fixed in 1.129.4.
CVSS 6.1
CVE-2025-59426 WRITEUP MEDIUM WRITEUP
lobehub/lobe_chat < 1.130.1 - Open Redirect via X-Forwarded-Host Header
Lobe Chat is an open-source artificial intelligence chat framework. Prior to version 1.130.1, the project's OIDC redirect handling logic constructs the host and protocol of the final redirect URL based on the X-Forwarded-Host or Host headers and the X-Forwarded-Proto value. In deployments where a reverse proxy forwards client-supplied X-Forwarded-* headers to the origin as-is, or where the origin trusts them without validation, an attacker can inject an arbitrary host and trigger an open redirect that sends users to a malicious domain. This issue has been patched in version 1.130.1.
CVSS 4.3
CVE-2026-23522 WRITEUP LOW WRITEUP
LobeChat <2.0.0-next.193 - Privilege Escalation
LobeChat is an open source chat application platform. Prior to version 2.0.0-next.193, `knowledgeBase.removeFilesFromKnowledgeBase` tRPC ep allows authenticated users to delete files from any knowledge base without verifying ownership. `userId` filter in the database query is commented out, so it's enabling attackers to delete other users' KB files if they know the knowledge base ID and file ID. While the vulnerability is confirmed, practical exploitation requires knowing target's KB ID and target's file ID. These IDs are random and not easily enumerable. However, IDs may leak through shared links, logs, referrer headers and so on. Missing authorization check is a critical security flaw regardless. Users should upgrade to version 2.0.0-next.193 to receive a patch.
