| CVE-2026-44555 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 7.6 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, Open WebUI supports model composition via base_model_id: a user-defined model (e.g., "Cheap Assistant") can reference an existing base model (e.g., "gpt-4-turbo-restricted") that provides the actual inference capability. When a user queries the composed model, the access control pipeline verifies the user has access to the composed model but never re-verifies access to the chained base model. Additionally, the model creation and import endpoints accept arbitrary base_model_id values without checking that the caller has access to that base model. Combined, this allows any user with the default model creation permission to create a model that chains to a restricted base model — and then invoke it, causing the server to dispatch the request to the restricted base model using the admin-configured API key. This vulnerability is fixed in 0.9.0. | ||||
| CVE-2026-44554 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 8.1 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the POST /api/v1/retrieval/process/web endpoint accepts a user-supplied collection_name and an overwrite query parameter (default: True). It performs no authorization check on whether the calling user owns or has write access to the target collection. When overwrite=True, save_docs_to_vector_db calls VECTOR_DB_CLIENT.delete_collection() on the target collection before writing new content. This vulnerability is fixed in 0.9.0. | ||||
| CVE-2026-45671 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 8 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, any authenticated user can permanently delete files owned by other users via DELETE /api/v1/files/{id} when the target file is referenced in any shared chat. The has_access_to_file() authorization gate unconditionally grants access through its shared-chat branch. It checks neither the requesting user's identity nor the type of operation being performed. File UUIDs (which would otherwise be impractical to guess) are disclosed to any user with read access to a knowledge base via GET /api/v1/knowledge/{id}/files. This vulnerability is fixed in 0.9.0. | ||||
| CVE-2026-45399 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 7.1 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, any authenticated user with low privileges can enumerate active background tasks across the system and stop tasks belonging to other users via the GET /api/tasks and POST /api/tasks/stop/{task_id} methods. This allows a casual user to disrupt system-wide chat usage by continuously canceling other users' active tasks. This is a real authorization vulnerability affecting integrity and usability in multi-user deployments. This vulnerability is fixed in 0.9.0. | ||||
| CVE-2026-45331 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 8.5 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, validate_url() in backend/open_webui/retrieval/web/utils.py calls validators.ipv6(ip, private=True), but the validators library does NOT implement the private keyword for IPv6 — the call raises a ValidationError (which is falsy in a boolean context), so every IPv6 address passes the filter. In addition, IPv4-mapped IPv6 (::ffff:10.0.0.1) bypasses the IPv4 check entirely, and several reserved IPv4 ranges (0.0.0.0/8, 100.64.0.0/10, 192.0.0.0/24, etc.) are not blocked. This vulnerability is fixed in 0.9.0. | ||||
| CVE-2026-45395 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 7.2 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, the tool update endpoint (POST /api/v1/tools/id/{id}/update) is missing the workspace.tools permission check that is present on the tool create endpoint. This allows a user who has been explicitly denied tool management capabilities ( and who the administrator considers untrusted for code execution ) to replace a tool's server-side Python content and trigger execution, bypassing the intended workspace.tools security boundary. This vulnerability is fixed in 0.9.5. | ||||
| CVE-2026-45242 | 1 Steipete | 1 Summarize | 2026-05-19 | 7.1 High |
| Summarize prior to 0.15.1 contains a path traversal vulnerability in the /v1/summarize daemon endpoint that allows authenticated callers to write files to arbitrary directories by supplying an absolute path or directory traversal sequence in the slidesDir request parameter. Attackers can exploit this to write slide_*.png and slides.json files to any writable directory and subsequently delete matching files at the specified location through repeat extraction. | ||||
| CVE-2026-45245 | 1 Steipete | 1 Summarize | 2026-05-19 | 7.4 High |
| Summarize prior to 0.15.1 contains a vulnerability in the hover summary feature that allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links, causing the extension to make authenticated daemon requests using stored tokens without verifying event trustworthiness. Attackers can place local or private-network URLs behind hoverable links to route authenticated requests through the daemon, potentially accessing sensitive internal endpoints when users interact with attacker-controlled content. | ||||

| CVE-2026-45665 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-19 | 8.1 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.0, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Banner component due to an improper sanitization order (specifically, DOMPurify is executed before the marked library). This vulnerability allows a compromised or malicious administrator to plant a malicious payload in the global banner. Crucially, this vector enables Privilege Escalation, as the malicious banner is rendered for all users, including the Super Admin (Primary Admin). Consequently, the payload successfully bypasses the existing security mechanism. An attacker can leverage this to steal the Super Admin's session token This vulnerability is fixed in 0.8.0. | ||||
| CVE-2025-56352 | 1 Justdoit0910 | 1 Tinymqtt | 2026-05-18 | 7.5 High |
| In tinyMQTT commit 6226ade15bd4f97be2d196352e64dd10937c1962 (2024-02-18), the broker mishandles protocol violations during CONNECT packet parsing. When receiving a CONNECT packet with a zero-length Client ID while CleanSession is set to 0, the broker correctly replies with a CONNACK return code 0x02 (Identifier Rejected) but fails to explicitly close the TCP connection. Since the surrounding connection teardown logic is not guaranteed to execute, each such invalid CONNECT attempt leaves the underlying socket open. Repeated attempts cause server-side resource exhaustion due to accumulating file descriptors and memory usage, potentially resulting in denial of service. | ||||
