| CVE-2026-109298 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.5 Medium |
| Open WebUI 0.11.0 before 0.11.4 compiles user-chosen grep patterns for its knowledge and chat file search tools with a regex engine that expands nested counted repetition unbounded at compile time and caches the result. Authenticated users can have the model call grep_knowledge_files with short nested-repetition patterns, blocking the event loop and exhausting worker memory. | ||||
| CVE-2026-109297 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.5 Medium |
| Open WebUI 0.11.0 before 0.11.4 contains a denial of service vulnerability in the automation recurrence-rule validator, whose sub-daily frequency guard parses rule text more strictly than the calendar library that executes it. Users permitted to create automations can submit whitespace-folded rules (or, in 0.11.0, lowercase frequencies or omitted RRULE prefixes) that expand per-second synchronously, blocking the shared event loop for minutes per request and on every scheduler poll. | ||||
| CVE-2026-109296 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 4.3 Medium |
| Open WebUI before 0.11.4 contains a missing authorization vulnerability that allows authenticated users to reach disabled model provider backends by supplying an explicit backend index. Attackers can pass the index as a path segment or query parameter on Ollama and OpenAI-compatible listing routes to trigger requests carrying configured API keys, read version strings, and enumerate connections. | ||||
| CVE-2026-109295 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.5 Medium |
| Open WebUI from 0.11.0 before 0.11.4 contains a regular expression denial of service vulnerability that allows authenticated users to stall server workers via file search patterns. Attackers can instruct the model to call grep_knowledge_files or grep_chat_files with a catastrophically backtracking regex, blocking the event loop for two seconds per repeated call. | ||||
| CVE-2026-109294 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.5 Medium |
| Open WebUI from 0.6.42 before 0.11.4 contains an uncontrolled resource consumption vulnerability that allows authenticated users to exhaust server memory by supplying compressed remote image URLs in chat messages. Attackers can point the image field at a host returning gzip-encoded responses, which get_image_base64_from_url decompresses unbounded, causing denial of service for all users. | ||||
| CVE-2026-109293 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.5 Medium |
| Open WebUI from 0.11.0 before 0.11.4 contains an information disclosure vulnerability that allows authenticated non-admin users with tool export permission to obtain tool source code shared with them read-only. Attackers can request GET /api/v1/tools/export to retrieve the full Python source of read-only shared tools, exposing embedded API keys and credentials. | ||||
| CVE-2026-109292 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.8 Medium |
| Open WebUI from 0.6.27 before 0.11.4 contains an information disclosure vulnerability that allows destination servers to obtain user session cookies by receiving the full browser cookie jar on OAuth-mode connections. Operators of OpenAI-compatible connections, OpenAPI tool servers or terminal servers can capture forwarded session cookies from routine requests and replay them to hijack accounts, including administrators. | ||||
| CVE-2026-109291 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 7.3 High |
| Open WebUI from 0.6.33 before 0.11.4 contains a cross-site scripting vulnerability that allows authenticated users to execute script in victims' sessions by storing javascript: URLs in citation embed_url fields. Attackers can share a crafted chat whose citation, when clicked, is passed to window.open, letting them steal localStorage.token and act as the victim. | ||||
| CVE-2026-109290 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 7.3 High |
| Open WebUI from 0.11.1 before 0.11.4 contains a stored cross-site scripting vulnerability in DocxPreview.svelte that allows authenticated users to execute script by uploading crafted DOCX attachments. Attackers can embed an OOXML altChunk HTML part or script-scheme hyperlink to steal a previewing administrator's session token from local storage and take over the instance. | ||||
| CVE-2026-109289 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.3 Medium |
| Open WebUI from 0.8.8 before 0.11.4 contains an improper authorization vulnerability that allows deactivated users to keep executing terminal commands through an already open terminal WebSocket. Because the terminal proxy route in terminals.py checks access only on the first message, deactivated users can keep running commands and reading or writing files on the terminal server. | ||||
| CVE-2026-109288 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 6.4 Medium |
| Open WebUI before 0.11.4 contains a stored cross-site scripting vulnerability in MarkdownInlineTokens.svelte, which renders markdown link URLs into anchor hrefs without validating their scheme. Authenticated users can embed javascript: links in shared chats that, when clicked by a victim, steal the victim's JWT from local storage, including admins' tokens. | ||||
| CVE-2026-109287 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 4.3 Medium |
| Open WebUI from 0.9.6 before 0.11.4 contains an authorization flaw where the knowledge base file listing does not verify that a supplied directory_id belongs to the requested knowledge base. Users with read access to any knowledge base can supply a retained foreign directory UUID to GET /api/v1/knowledge/{id}/files. The returned breadcrumbs expose folder names, owner user ids and knowledge base ids of that directory and all its ancestors. | ||||
| CVE-2026-109286 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 8.1 High |
| Open WebUI from 0.7.0 before 0.11.4 contains a cross-origin message handling vulnerability in SyncStatsModal that allows any website to steal a signed-in user's session token by posting unvalidated verify:chat messages. Attackers can supply a path-traversal chat id redirecting the authenticated stats export request to the auths endpoint, receiving the victim's JWT for full API access. | ||||
| CVE-2026-109285 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 5 Medium |
| Open WebUI from 0.6.0 before 0.11.4 contains an improper access control vulnerability in has_access_to_file that lets former knowledge base collaborators keep file access via stale cached knowledge base references. Attackers with read or write grants can download removed files through the file content endpoint or delete them, including from the owner's private knowledge bases. | ||||
| CVE-2026-109284 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 4.3 Medium |
| Open WebUI from 0.11.0 before 0.11.4 contains an improper authorization vulnerability in the chat fork handler, which places forked chats in the source chat's folder without checking folder write access. Shared folder members downgraded to read-only can call POST /api/v1/chats/{id}/fork on chats they created there while they had write access, inserting attacker-controlled chats visible to the folder owner and members. | ||||
| CVE-2026-109283 | 1 Openwebui | 1 Open Webui | 2026-10-12 | 5.4 Medium |
| Open WebUI from 0.11.1 before 0.11.4 contains an authorization bypass in the OAuth token exchange endpoint, which reads role claims only from the provider's userinfo response and keeps the user's existing role when no roles claim is found, ignoring roles sent only in the ID token. Users with a linked account whose identity provider role no longer satisfies the OAuth role policy can send a valid provider access token to POST /api/v1/auths/oauth/{provider}/token/exchange to obtain a session retaining their previous role. | ||||
| CVE-2026-109282 | 1 Imagemagick | 1 Imagemagick | 2026-10-12 | 2.5 Low |
| ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a type confusion flaw in the INFO, JSON and YAML encoders, where an internal method receives a pointer of an unexpected type when writing an image in a compressed format. An attacker who can cause such an image write can trigger a SIGABRT or SIGSEGV, crashing the process and causing denial of service. | ||||
| CVE-2026-109281 | 1 Imagemagick | 1 Imagemagick | 2026-10-12 | 4.4 Medium |
| ImageMagick 7.1.0-21 before 7.1.2-32 contains a heap buffer over-read in its handling of the -fx option, where a certain -fx operation reads beyond the bounds of an allocated heap buffer in specific situations. Attackers who can get a crafted -fx expression processed can read out-of-bounds heap memory, potentially disclosing limited memory contents. | ||||
| CVE-2026-109280 | 1 Imagemagick | 1 Imagemagick | 2026-10-12 | 2.5 Low |
| ImageMagick 7.1.0-20 before 7.1.2-32 contains a use after free vulnerability in the -fx option that occurs when a memory allocation fails during a specific operation. Attackers who can supply crafted -fx expressions under memory pressure can trigger freed memory access, causing crashes or memory corruption. | ||||
| CVE-2026-109279 | 1 Imagemagick | 1 Imagemagick | 2026-10-12 | 2.5 Low |
| ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 lacks proper synchronization when the security policy is accessed, so simultaneous reads and writes of the policy by multiple threads trigger a race condition that causes a heap buffer over-write. An attacker able to induce concurrent security policy access can crash the application, causing a denial of service. | ||||
