| CVE-2026-56398 | 1 Openwebui | 1 Open Webui | 2026-07-16 | N/A | 7.3 HIGH |
| Open WebUI before 0.9.5 contains a stored cross-site scripting vulnerability in the OAuth authentication flow where the picture claim URL MIME type is inferred from file extension rather than Content-Type header, allowing SVG files to bypass the profile image validator and be stored as data URIs. Authenticated users who visit the profile image endpoint receive attacker-controlled SVG content with inline disposition and no default security headers, enabling script execution in the same origin to steal authentication tokens and achieve account takeover. | |||||
| CVE-2026-56400 | 1 Openwebui | 1 Open Webui | 2026-07-16 | N/A | 8.3 HIGH |
| open-webui before 0.3.14 contains a cross-origin resource sharing misconfiguration allowing arbitrary origins with allow_origins=* and authenticated requests to the /api/v1/functions endpoint. Attackers can execute arbitrary code on the openwebui instance by crafting malicious cross-site requests from attacker-controlled websites when an admin user visits them. | |||||
| CVE-2026-59227 | 1 Openwebui | 1 Open Webui | 2026-07-14 | N/A | 4.3 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.11 before 0.10.0, POST /api/v1/images/edit required only a verified account and did not enforce the global image-edit switch or the per-user image-generation permission, allowing a non-admin user to invoke server-side image editing with administrator-configured provider credentials. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59217 | 1 Openwebui | 1 Open Webui | 2026-07-14 | N/A | 4.3 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, the file upload path accepted metadata.knowledge_id and auto-linked uploaded files to a target knowledge base without applying the write-access check used by /api/v1/knowledge//file/add, allowing read-only knowledge-base users to add arbitrary files. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59215 | 1 Openwebui | 1 Open Webui | 2026-07-13 | N/A | 3.1 LOW |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, channel thread parent and reply handling did not bind parent_id to the channel in the URL, allowing an authenticated user to reference a message from another private or DM channel and disclose thread context across channels. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59216 | 1 Openwebui | 1 Open Webui | 2026-07-13 | N/A | 7.7 HIGH |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, get_event_call delivered execute:python and execute:tool Socket.IO events to a client-supplied session_id after checking only that the session was connected, allowing authenticated users who learned another socket ID through ydoc:document:join to run code interpreter Python or tools in that user session. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59212 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 5.4 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 before 0.10.0, _verify_knowledge_file_access only checked read access while file write and delete routes later trusted object-derived access through writable model meta.knowledge entries, allowing a user with read-only knowledge file access to upgrade to file write or delete operations. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59213 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 3.5 LOW |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.27 before 0.10.0, get_all_models handlers in routers/openai.py and routers/ollama.py passed a lambda to aiocache key instead of key_builder, causing permission-filtered per-user model lists to share a static cache entry and exposing one user’s model list to another caller during the TTL window. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59214 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 7.3 HIGH |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, Open WebUI runs client-side Python with Pyodide in a same-origin web worker, allowing stored chat payloads that use pyodide.http.pyfetch or the js module fetch and XMLHttpRequest APIs to issue authenticated same-origin requests when a victim clicks Run, which can reach admin-only endpoints and execute server-side code through configured tools. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59218 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 5.3 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, the /api/v1/auths/signin endpoint looked users up by email and only ran bcrypt password verification when a credential existed, making registered-account attempts measurably slower than missing-email attempts and allowing unauthenticated account enumeration. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59219 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 7.1 HIGH |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 before 0.10.0 with Redis configured, Socket.IO connect, user-join, join-channels, join-note, and the terminal websocket first-message authentication used decode_token without the Redis-backed is_valid_token revocation check, allowing revoked JWTs to continue authenticating realtime connections. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59220 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 6.5 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.2 before 0.10.0, the SKILL_MENTION_RE and strip_re regular expressions in backend/open_webui/utils/middleware.py parsed <$skillId|label> skill mentions with overlapping quantifiers, allowing an authenticated chat message containing <$ without a closing > to trigger quadratic backtracking and block the asyncio event loop. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59222 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 6.5 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.7.0 before 0.10.0, GET /api/v1/channels//members returned full UserModelResponse objects for channel members, including settings.ui.toolServers[].key and webhook configuration, allowing a normal channel participant to retrieve other users’ sensitive settings. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59223 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 4.3 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, WEB_FETCH_FILTER_LIST matching compared configured host entries against URL strings and non-label-boundary suffixes, allowing path-based blocklist bypasses such as !internal.example.com in a URL path and sibling-domain matches that did not reflect the intended hostname policy. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59224 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 8.0 HIGH |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, backend/open_webui/routers/terminals.py built the ws_terminal upstream URL from an unencoded session_id and appended user_id as a query parameter, allowing query injection to make the terminal backend resolve another user identity; the HTTP proxy path also forwarded X-User-Id as an integrity-unbound identity claim. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59225 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 5.4 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.12 before 0.10.0, an authenticated non-admin user with read access to an arena wrapper model can reach a restricted underlying model through task endpoints such as /api/v1/tasks/moa/completions. The normal chat route resolves arena models before the final chat dispatch and therefore re-checks the selected underlying model. The task routes call utils.chat.generate_chat_completion() directly. In that direct path, arena fallback resolution happens after the wrapper access check and then recurses with bypass_filter=True, skipping the selected submodel's access check. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59226 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 3.1 LOW |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 before 0.10.0, execute_automation rehydrated automation owners without rechecking that they were still active or still had features.automations, and check_model_access only enforced private-model grants for the exact user role, allowing deactivated pending users to continue scheduled model execution. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59715 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 3.1 LOW |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.16 before 0.10.0, the Socket.IO server is configured with always_connect=True. The ydoc:awareness:update and ydoc:document:leave Socket.IO handlers accepted collaborative-document events without requiring an authenticated user, allowing unauthorized manipulation of document collaboration state. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-59221 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 7.7 HIGH |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 before 0.10.0, _sanitize_proxy_path in backend/open_webui/routers/terminals.py decoded proxy paths only eight times, allowing a nine-times percent-encoded ../ traversal value to pass normalization checks and be decoded by the upstream terminal server. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-54021 | 1 Openwebui | 1 Open Webui | 2026-06-26 | N/A | 6.3 MEDIUM |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, several direct, index-addressed Ollama proxy routes accept a caller-supplied url_idx path parameter and use it as a raw index into the admin-configured OLLAMA_BASE_URLS list. Access control on these routes validates only whether the user may use the requested model, never which backend the request is routed to. Any authenticated user can append an arbitrary url_idx to force their request onto an Ollama backend they were never authorized to reach, including internal, higher-privilege, or explicitly admin-disabled backends. This vulnerability is fixed in 0.9.6. | |||||
