CVE-2026-44549

Open WebUI: Stored XSS in excel file preview

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.0, Excel file attachments are previewed in an unsafe way. A crafted XLSX file payload can be used to cause the sheetjs function sheet_to_html to embed an XSS payload into the generated HTML. This is subsequently added to the DOM unsanitized via @html causing the payload to trigger. This vulnerability is fixed in 0.8.0.

Open WebUI: Open WebUI Arbitrary File Write, Delete via Path Traversal

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.6.10, when uploading an audio file, the name of the file is derived from the original HTTP upload request and is not validated or sanitized. This allows for users to upload files with names containing dot-segments in the file path and traverse out of the intended uploads directory. Effectively, users can upload files anywhere on the filesystem the user running the web server has permission. This vulnerability is fixed in 0.6.10.

Open WebUI: Insecure Message Access Breaks Authorization

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.6.19, there's an IDOR in the channels message management system that allows authenticated users to modify or delete any message within channels they have read access to. The vulnerability exists in the message update and delete endpoints, which implement channel-level authorization but completely lack message ownership validation. While the frontend correctly implements ownership checks (showing edit/delete buttons only for message owners or admins), the backend APIs bypass these protections by only validating channel access permissions without verifying that the requesting user owns the target message. This creates a client-side security control bypass where attackers can directly call the APIs to modify other users' messages. This vulnerability is fixed in 0.6.19.

Open WebUI: Open WebUI Improper Authorization Control

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.1.124, the API does not properly validate that the user has an authorized user role of user. By default, when Open WebUI is configured with new sign-ups enabled, the default user role is set to pending. In this configuration, an administrator is required to go into the Admin management panel following a new user registration and reconfigure the user to have a role of either user or admin before that user is able to access the web application. This vulnerability is fixed in 0.1.124.

Division by Zero in GStreamer MP4 Audio Parser Leading to Denial of Service

An issue was discovered in GStreamer gst-plugins-good before 1.28.2. When parsing MP4 audio tracks, the isomp4 plugin's qtdemux_audio_caps function does not sufficiently validate atom data before performing division operations, leading to denial of service due to integer division by zero.

CVE-2026-8912

Contest Gallery <= 28.1.6 - Unauthenticated SQL Injection

The Contest Gallery plugin for WordPress is vulnerable to SQL Injection via the 'form_input' parameter in versions up to, and including, 28.1.6. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query inside the unauthenticated 'post_cg_gallery_form_upload' AJAX action (specifically the 'cb' branch of the included users-upload-check.php, where $f_input_id is concatenated unquoted into 'SELECT Field_Content FROM ... WHERE id = $f_input_id'). The endpoint is gated only by a public frontend nonce ('cg1l_action' / 'cg_nonce') that is exposed in the page source of any public gallery page. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Pocketbase: Account pre-hijacking via OAuth2 unverfied->verified autolinking upgrade

Pocketbase is an open source web backend written in go. Prior to 0.22.42 and 0.37.4, in some situations, if an attacker knows the email address of the victim they can create and link an unverified PocketBase user in advance by authenticating with one of the OAuth2 app providers, e.g. "A". When the victim gets invited or decides to sign up to your app on their own with provider "B" (PocketBase OAuth2 auth requires to be with a different provider because we don't allow multiple OAuth2 accounts from the same provider to be associated to a single PocketBase user), the user created previously by the attacker will be autolinked, upgraded to "verified" and its old password reset. This vulnerability is fixed in 0.22.42 and 0.37.4.
