CVE-2026-28788 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-04-02 7.1 High
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to version 0.8.6, any authenticated user can overwrite any file's content by ID through the `POST /api/v1/retrieval/process/files/batch` endpoint. The endpoint performs no ownership check, so a regular user with read access to a shared knowledge base can obtain file UUIDs via `GET /api/v1/knowledge/{id}/files` and then overwrite those files, escalating from read to write. The overwritten content is served to the LLM via RAG, meaning the attacker controls what the model tells other users. Version 0.8.6 patches the issue.
CVE-2026-29071 2 Open-webui, Openwebui 2 Open-webui, Open Webui 2026-04-02 3.1 Low
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to version 0.8.6, any authenticated user can read other users' private memories via `/api/v1/retrieval/query/collection`. Version 0.8.6 patches the issue.
CVE-2026-33730 1 Opensourcepos 2 Open Source Point Of Sale, Opensourcepos 2026-04-02 6.5 Medium
Open Source Point of Sale (opensourcepos) is a web based point of sale application written in PHP using CodeIgniter framework. Prior to version 3.4.2, an Insecure Direct Object Reference (IDOR) vulnerability allows an authenticated low-privileged user to access the password change functionality of other users, including administrators, by manipulating the `employee_id` parameter. The application does not verify object ownership or enforce authorization checks. Version 3.4.2 adds object-level authorization checks to validate that the current user owns the employee_id being accessed.
CVE-2026-33735 1 Franklioxygen 1 Mytube 2026-04-02 8.8 High
MyTube is a self-hosted downloader and player for several video websites Prior to version 1.8.69, an authorization bypass in the `/api/settings/import-database` endpoint allows attackers with low-privilege credentials to upload and replace the application's SQLite database entirely, leading to a full compromise of the application. The bypass is relevant for other POST routes as well. Version 1.8.69 fixes the issue.
CVE-2026-33764 1 Wwbn 1 Avideo 2026-04-02 4.3 Medium
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the AI plugin's `save.json.php` endpoint loads AI response objects using an attacker-controlled `$_REQUEST['id']` parameter without validating that the AI response belongs to the specified video. An authenticated user with AI permissions can reference any AI response ID — including those generated for other users' private videos — and apply the stolen AI-generated content (titles, descriptions, keywords, summaries, or full transcriptions) to their own video, effectively exfiltrating the information. Commit aa2c46a806960a0006105df47765913394eec142 contains a patch.
CVE-2026-33030 2 0xjacky, Nginxui 2 Nginx-ui, Nginx Ui 2026-04-02 8.8 High
Nginx UI is a web user interface for the Nginx web server. In versions 2.3.3 and prior, Nginx-UI contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user to access, modify, and delete resources belonging to other users. The application's base Model struct lacks a user_id field, and all resource endpoints perform queries by ID without verifying user ownership, enabling complete authorization bypass in multi-user environments. At time of publication, there are no publicly available patches.
CVE-2026-5199 2026-04-01 N/A
A writer role user in an attacker-controlled namespace could signal, delete, and reset workflows or activities in a victim namespace on the same cluster. Exploitation requires the attacker to know or guess specific victim workflow ID(s) and, for signal operations, signal names. This was due to a bug introduced in Temporal Server v1.29.0 which inadvertently allowed an attacker to control the namespace name value instead of using the server's own trusted name value within the batch activity code. The batch activity validated the namespace ID but did not cross-check the namespace name against the worker's bound namespace, allowing the per-namespace worker's privileged credentials to operate on an arbitrary namespace. Exploitation requires a server configuration where internal components have cross-namespace authorization, such as deployment of the internal-frontend service or equivalent TLS-based authorization for internal identities. This vulnerability also impacted Temporal Cloud when the attacker and victim namespaces were on the same cell, with the same preconditions as self-hosted clusters.
CVE-2026-3321 1 On24 2 On24 Q&a Chat, On24 Q A Chat 2026-04-01 N/A
A vulnerability of authorization bypass through user-controlled key in the 'console-survey/api/v1/answer/{EVENTID}/{TIMESTAMP}/' endpoint. Exploiting this vulnerability would allow an unauthenticated attacker to enumerate event IDs and obtain the complete Q&A history. This publicly exposed data may include IDs, private URLs, private messages, internal references, or other sensitive information that should only be exposed to authenticated users. In addition, the leaked content could be exploited to facilitate other malicious activities, such as reconnaissance for lateral movement, exploitation of related systems, or unauthorised access to internal applications referenced in the content of chat messages.
CVE-2026-34046 1 Langflow 2 Langflow, Langflow-base 2026-04-01 N/A
Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.5.1, the `_read_flow` helper in `src/backend/base/langflow/api/v1/flows.py` branched on the `AUTO_LOGIN` setting to decide whether to filter by `user_id`. When `AUTO_LOGIN` was `False` (i.e., authentication was enabled), neither branch enforced an ownership check — the query returned any flow matching the given UUID regardless of who owned it. This allowed any authenticated user to read any other user's flow, including embedded plaintext API keys; modify the logic of another user's AI agents, and/or delete flows belonging to other users. The vulnerability was introduced by the conditional logic that was meant to accommodate public/example flows (those with `user_id = NULL`) under auto-login mode, but inadvertently left the authenticated path without an ownership filter. The fix in version 1.5.1 removes the `AUTO_LOGIN` conditional entirely and unconditionally scopes the query to the requesting user.
CVE-2026-33759 1 Wwbn 1 Avideo 2026-03-31 5.3 Medium
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/playlistsVideos.json.php` endpoint returns the full video contents of any playlist by ID without any authentication or authorization check. Private playlists (including `watch_later` and `favorite` types) are correctly hidden from listing endpoints via `playlistsFromUser.json.php`, but their contents are directly accessible through this endpoint by providing the sequential integer `playlists_id` parameter. Commit bb716fbece656c9fe39784f11e4e822b5867f1ca has a patch for the issue.
CVE-2026-31950 2 Danny-avila, Librechat 2 Libre Chat, Librechat 2026-03-31 5.3 Medium
LibreChat is a ChatGPT clone with additional features. In versions 0.8.2-rc2 through 0.8.2-rc3, the SSE streaming endpoint `/api/agents/chat/stream/:streamId` does not verify that the requesting user owns the stream. Any authenticated user who obtains or guesses a valid stream ID can subscribe and read another user's real-time chat content, including messages, AI responses, and tool invocations. Version 0.8.2 patches the issue.
CVE-2026-33663 1 N8n 1 N8n 2026-03-31 6.5 Medium
n8n is an open source workflow automation platform. Prior to versions 2.14.1, 2.13.3, and 1.123.27, an authenticated user with the `global:member` role could exploit chained authorization flaws in n8n's credential pipeline to steal plaintext secrets from generic HTTP credentials (`httpBasicAuth`, `httpHeaderAuth`, `httpQueryAuth`) belonging to other users on the same instance. The attack abuses a name-based credential resolution path that does not enforce ownership or project scope, combined with a bypass in the credentials permission checker that causes generic HTTP credential types to be skipped during pre-execution validation. Together, these flaws allow a member-role user to resolve another user's credential ID and execute a workflow that decrypts and uses that credential without authorization. Native integration credential types (e.g. `slackApi`, `openAiApi`, `postgres`) are not affected by this issue. This vulnerability affects Community Edition only. Enterprise Edition has additional permission gates on workflow creation and execution that independently block this attack chain. The issue has been fixed in n8n versions 1.123.27, 2.13.3, and 2.14.1. Users should upgrade to one of these versions or later to remediate the vulnerability. If upgrading is not immediately possible, administrators should consider the following temporary mitigations: Restrict instance access to fully trusted users only, and/or audit credentials stored on the instance and rotate any generic HTTP credentials (`httpBasicAuth`, `httpHeaderAuth`, `httpQueryAuth`) that may have been exposed. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
CVE-2026-32867 2 Opexus, Opexustech 2 Ecomplaint, Ecase Ecomplaint 2026-03-30 5.4 Medium
OPEXUS eComplaint before version 10.1.0.0 allows an unauthenticated attacker to obtain or guess an existing case number and upload arbitrary files via 'Portal/EEOC/DocumentUploadPub.aspx'. Users would see these unexpected files in cases. Uploading a large number of files could consume storage.
CVE-2026-33678 2 Go-vikunja, Vikunja 2 Vikunja, Vikunja 2026-03-30 8.1 High
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, `TaskAttachment.ReadOne()` queries attachments by ID only (`WHERE id = ?`), ignoring the task ID from the URL path. The permission check in `CanRead()` validates access to the task specified in the URL, but `ReadOne()` loads a different attachment that may belong to a task in another project. This allows any authenticated user to download or delete any attachment in the system by providing their own accessible task ID with a target attachment ID. Attachment IDs are sequential integers, making enumeration trivial. Version 2.2.1 patches the issue.
CVE-2026-33700 2 Go-vikunja, Vikunja 2 Vikunja, Vikunja 2026-03-30 4.9 Medium
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the `DELETE /api/v1/projects/:project/shares/:share` endpoint does not verify that the link share belongs to the project specified in the URL. An attacker with admin access to any project can delete link shares from other projects by providing their own project ID combined with the target share ID. Version 2.2.1 patches the issue.
CVE-2026-28503 2 Tandoor, Tandoorrecipes 2 Recipes, Recipes 2026-03-30 6.5 Medium
Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the `SyncViewSet.query_synced_folder()` action in `cookbook/views/api.py` (line 903) fetches a Sync object using `get_object_or_404(Sync, pk=pk)` without including `space=request.space` in the filter. This allows an admin user in Space A to trigger sync operations (Dropbox/Nextcloud/Local import) on Sync configurations belonging to Space B, and view the resulting sync logs. Version 2.6.0 patches the issue.
CVE-2026-32535 2 Joomsky, Wordpress 2 Js Help Desk, Wordpress 2026-03-30 6.5 Medium
Authorization Bypass Through User-Controlled Key vulnerability in JoomSky JS Help Desk js-support-ticket allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects JS Help Desk: from n/a through <= 3.0.3.
CVE-2026-32533 2 Latepoint, Wordpress 2 Latepoint, Wordpress 2026-03-30 6.5 Medium
Authorization Bypass Through User-Controlled Key vulnerability in LatePoint LatePoint latepoint allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects LatePoint: from n/a through <= 5.2.6.
CVE-2026-1206 2 Elemntor, Wordpress 2 Elementor Website Builder – More Than Just A Page Builder, Wordpress 2026-03-30 4.3 Medium
The Elementor Website Builder plugin for WordPress is vulnerable to Incorrect Authorization to Sensitive Information Exposure in all versions up to, and including, 3.35.7. This is due to a logic error in the is_allowed_to_read_template() function permission check that treats non-published templates as readable without verifying edit capabilities. This makes it possible for authenticated attackers, with contributor-level access and above, to read private or draft Elementor template content via the 'template_id' supplied to the 'get_template_data' action of the 'elementor_ajax' endpoint.
CVE-2026-1496 1 Black Duck 1 Coverity 2026-03-30 N/A
Vulnerable versions of Coverity Connect lack an error handler in the authentication logic for command line tooling that makes it vulnerable to an authentication bypass. A malicious actor with access to the /token API endpoint that either knows or guesses a valid username, can use this in a specially crafted HTTP request to bypass authentication. Successful exploitation allows the malicious actor to assume all roles and privileges granted to the valid user’s Coverity Connect account.
