CVE-2026-42098 1 Sparxsystems 1 Enterprise Architect 2026-05-19 N/A
Sparx Enterprise Architect software has a security feature that limits user's actions to those specified in the role. An authenticated attacker can modify the Enterprise Architect client behavior (e.g. using a debugger) and log in as any other user or administrator - then it is possible to do every possible change to the repository. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 17.1 and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
CVE-2026-8568 1 Google 1 Chrome 2026-05-19 3.1 Low
Insufficient policy enforcement in AI in Google Chrome prior to 148.0.7778.168 allowed a remote attacker who had compromised the renderer process to bypass Site Isolation via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-8582 1 Google 1 Chrome 2026-05-19 5.3 Medium
Object lifecycle issue in Dawn in Google Chrome prior to 148.0.7778.168 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-47317 1 Samsung Open Source 1 Escargot 2026-05-19 5.5 Medium
Uncontrolled Recursion vulnerability in Samsung Open Source Escargot allows Excessive Allocation. This issue affects Escargot: 590345cc6258317c5da850d846ce6baaf2afc2d3.
CVE-2026-44552 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-19 8.7 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the tool_servers and terminal_servers keys in utils/tools.py do use a prefix. When two or more Open WebUI instances share a Redis database (a supported and documented deployment pattern, e.g., for multi-region deployments, blue-green setups, or cluster topologies), the unprefixed keys collide. An admin on Instance A writing to tool_servers overwrites the value read by Instance B — causing Instance B's users to receive Instance A's tool server configuration. This vulnerability is fixed in 0.9.0.
CVE-2026-8843 1 Mongodb 2 Mongodb, Mongodb Server 2026-05-19 6.5 Medium
Creating a "2dsphere_bucket" index on a non-timeseries bucket collection will succeed, but any subsequent attempt to insert a document which triggers updating that index will crash the server. A similar issue occurs when creating "queryable_encrypted_range" indices. This issue affects MongoDB Server v7.0 versions prior to 7.0.32, v8.0 versions prior to 8.0.21 and v8.2 versions prior to 8.2.6
CVE-2026-33052 1 Mantisbt 1 Mantisbt 2026-05-19 N/A
Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions 2.28.0 and 2.28.1 allow a low-privileged authenticated user assigned the "add_profile_threshold" permission to create a global profile despite not having manage_global_profile_threshold, by tampering with the user_id parameter in a valid profile creation request. This issue has been fixed in version 2.28.2.
CVE-2026-45349 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, a user just needs to use the API endpoint: /api/chat/completions with their own API key (generated in OWUI) and the Chat ID of another user to continue the conversation of the other user. This vulnerability is fixed in 0.9.0.
CVE-2026-47309 1 Samsung Open Source 1 Escargot 2026-05-19 5.5 Medium
Uncontrolled Recursion vulnerability in Samsung Open Source Escargot allows Oversized Serialized Data Payloads. This issue affects Escargot: 590345cc6258317c5da850d846ce6baaf2afc2d3.
CVE-2026-45386 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-19 4.3 Medium
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, Pin/Unpin is a write operation (modifies the message's is_pinned , pinned_by, pinned_at fields), but in standard channels it only checks read permission, allowing users with read-only access to pin/unpin any message. This vulnerability is fixed in 0.9.5.
CVE-2026-45398 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-19 7.5 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, _validate_collection_access() checks the user-memory-* and file-* collection name prefixes but does not check knowledge base collections, which use raw UUIDs as collection names. Any authenticated user who knows a private knowledge base UUID can read its content through the retrieval query endpoints, even though the knowledge API correctly denies that user access. The same gap affects the retrieval write endpoints (/process/text, /process/file, /process/files/batch, /process/web, /process/youtube), allowing an attacker to inject content into or overwrite another user's knowledge base. This vulnerability is fixed in 0.9.5.
CVE-2026-41525 1 Kde 1 Dolphin 2026-05-19 6.5 Medium
KDE Dolphin before 25.12.3 allows applications in a Flatpak (or with AppArmor confinement) to open folders outside of the application sandbox without additional scrutiny. Dolphin's implementation of the FileManager1 protocol allows the path given to be any type of file, including scripts or executables. (By default, Dolphin will then prompt the user to determine if they want to launch a script or executable; however, the intended behavior is to block the attempted action, not present a consent prompt.)
CVE-2026-44553 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, administrative role changes and user deletions do not iterate SESSION_POOL to disconnect affected sessions. As a result, a user whose admin role has been revoked retains admin privileges within their existing Socket.IO session for as long as they keep the connection alive (via automatic heartbeats). The gap is exclusive to the Socket.IO session cache. 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-2026-45385 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-19 4.3 Medium
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, an IDOR vulnerability exists in the Channels feature of Open WebUI, allowing any channel member to modify messages sent by other members (including administrators) within the same channel. In the update_message_by_id function, for group or dm type channels, only the caller's membership in the channel is checked via the is_user_channel_member function, without verifying message ownership. This allows any channel member to modify messages sent by other members within the same channel. This vulnerability is fixed in 0.9.5.
CVE-2026-45666 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-19 6.5 Medium
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.11, the API /api/v1/notes/{note_id} endpoint lacks proper authorization checks, allowing authenticated users to retrieve notes belonging to other users by guessing or enumerating UUIDs. This results in unauthorized disclosure of potentially sensitive or private user data. This vulnerability is fixed in 0.8.11.
CVE-2026-45402 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-18 8.1 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, multiple endpoints accept a user-supplied file_id and attach the referenced file to a resource the caller controls (folder knowledge, knowledge-base contents) without verifying that the caller owns or has been granted access to the file. The file's content then becomes reachable through the downstream RAG / file-content paths, allowing any authenticated user to exfiltrate any other user's private file — and on the knowledge-base path, also to overwrite it — given knowledge of the file's UUID. This affects backend/open_webui/routers/folders.py (POST /api/v1/folders/{id}/update), backend/open_webui/routers/knowledge.py (add_file_to_knowledge_by_id), and backend/open_webui/routers/knowledge.py (add_files_to_knowledge_by_id_batch). This vulnerability is fixed in 0.9.5.
CVE-2026-44570 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-05-18 8.3 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.6.19, authorization controls surrounding the memories API were inconsistent, resulting in the ability of a standard user to delete, restore, and view the contents of other users' memories. Using a newly created non-admin user with no existing memories, it is possible to view existing memories via POST /api/v1/memories/query. Similarly, even if a non-admin user cannot modify another user's memory data via POST /api/v1/memories/{memory_id}/update, the endpoint's response improperly leaks the content of that memory if a valid memory_id is known. The DELETE /api/v1/memories/{memory_id} can also be used by any user to delete an existing memory. Deleted memories can then be restored by calling the POST /api/v1/memories/{memory_id}/update endpoint again. This vulnerability is fixed in 0.6.19.
CVE-2026-4053 1 Mattermost 2 Mattermost, Mattermost Server 2026-05-18 3.1 Low
Mattermost versions 11.5.x <= 11.5.1, 10.11.x <= 10.11.13 fail to enforce the PostEditTimeLimit on non-message post fields which allows an authenticated user to modify post file attachments, props, and pin status after the edit window has expired via the post patch and update API endpoints.. Mattermost Advisory ID: MMSA-2026-00631
CVE-2026-42245 1 Ruby-lang 2 Net::imap, Net\ 2026-05-18 7.5 High
Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to versions 0.4.24, 0.5.14, and 0.6.4, Net::IMAP::ResponseReader has quadratic time complexity when reading large responses containing many string literals. A hostile server can send responses which are crafted to exhaust the client's CPU for a denial of service attack. This issue has been patched in versions 0.4.24, 0.5.14, and 0.6.4.
