Apr 22, 2026Squidex is an open source headless content management system and content management hub.CVE-2026-41177 · Other software · Squidex · reported by GitHubMedium 5.5
Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, the Squidex Restore API is vulnerable to Blind Server-Side Request Forgery (SSRF). The application fails to validate the URI scheme of the user-supplied `Url` parameter, allowing the use of the `file://` protocol. This allows an authenticated administrator to force the backend server to interact with the local filesystem, which can lead to Local File Interaction (LFI) and potential disclosure of sensitive system information through side-channel analysis of internal logs. Version 7.23.0 contains a fix.

Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, an SSRF vulnerability allows a user with asset upload permission to force the server to fetch arbitrary URLs, including localhost/private network targets, and persist the response as an asset. Version 7.23.0 contains a fix.

Apr 22, 2026Squidex is an open source headless content management system and content management hub.CVE-2026-41171 · Other software · Squidex · reported by GitHubHigh 7.3
Squidex is an open source headless content management system and content management hub. Versions prior to 7.23.0 have a Server-Side Request Forgery (SSRF) vulnerability due to missing SSRF protection on the `Jint` HTTP client used by scripting engine functions (`getJSON`, `request`, etc.). An authenticated user with low privileges (e.g., schema editing permissions) can force the server to make arbitrary outbound HTTP requests to attacker-controlled or internal endpoints. This allows access to internal services and cloud metadata endpoints (e.g., IMDS), potentially leading to credential exposure and lateral movement. Version 7.23.0 contains a fix.

Apr 22, 2026Squidex is an open source headless content management system and content management hub.CVE-2026-41170 · Other software · Squidex · reported by GitHubHigh 7.2
Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, the `RestoreController.PostRestoreJob` endpoint allows an administrator to supply an arbitrary URL for downloading backup archives. This URL is fetched using the "Backup" `HttpClient` without any SSRF protection. A malicious or compromised admin can use this endpoint to probe internal network services, access cloud metadata endpoints, or perform internal reconnaissance. The vulnerability is authenticated (Admin-only) but highly impactful, allowing potential access to sensitive internal resources. Version 7.23.0 contains a fix.

Jan 27, 2026Squidex is an open source headless content management system and content management hub.CVE-2026-24736 · Other software · Squidex · reported by GitHubCritical 9.1
Squidex is an open source headless content management system and content management hub. Versions of the application up to and including 7.21.0 allow users to define "Webhooks" as actions within the Rules engine. The url parameter in the webhook configuration does not appear to validate or restrict destination IP addresses. It accepts local addresses such as 127.0.0.1 or localhost. When a rule is triggered (Either manual trigger by manually calling the trigger endpoint or by a content update or any other triggers), the backend server executes an HTTP request to the user-supplied URL. Crucially, the server logs the full HTTP response in the rule execution log (lastDump field), which is accessible via the API. Which turns a "Blind" SSRF into a "Full Read" SSRF. As of time of publication, no patched versions are available.

Dec 7, 2023Squidex before 7.9.0 allows XSS via an SVG document to the Upload Assets feature.CVE-2023-46857 · Other software · Squidex.io · reported by MITREMedium 5.4
Squidex before 7.9.0 allows XSS via an SVG document to the Upload Assets feature. This occurs because there is an incomplete blacklist in the SVG inspection, allowing JavaScript in the SRC attribute of an IFRAME element. An authenticated attack with assets.create permission is required for exploitation.

Nov 7, 2023Squidex is an open source headless CMS and content management hub.CVE-2023-46253 · Other software · Squidex · reported by GitHubCritical 9.1
Squidex is an open source headless CMS and content management hub. Affected versions are subject to an arbitrary file write vulnerability in the backup restore feature which allows an authenticated attacker to gain remote code execution (RCE). Squidex allows users with the `squidex.admin.restore` permission to create and restore backups. Part of these backups are the assets uploaded to an App. For each asset, the backup zip archive contains a `.asset` file with the actual content of the asset as well as a related `AssetCreatedEventV2` event, which is stored in a JSON file. Amongst other things, the JSON file contains the event type (`AssetCreatedEventV2`), the ID of the asset (`46c05041-9588-4179-b5eb-ddfcd9463e1e`), its filename (`test.txt`), and its file version (`0`). When a backup with this event is restored, the `BackupAssets.ReadAssetAsync` method is responsible for re-creating the asset. For this purpose, it determines the name of the `.asset` file in the zip archive, reads its content, and stores the content in the filestore. When the asset is stored in the filestore via the UploadAsync method, the assetId and fileVersion are passed as arguments. These are further passed to

Nov 7, 2023Squidex is an open source headless CMS and content management hub.CVE-2023-46252 · Other software · Squidex · reported by GitHubMedium 6.8
Squidex is an open source headless CMS and content management hub. Affected versions are missing origin verification in a postMessage handler which introduces a Cross-Site Scripting (XSS) vulnerability. The editor-sdk.js file defines three different class-like functions, which employ a global message event listener: SquidexSidebar, SquidexWidget, and SquidexFormField. The registered event listener takes some action based on the type of the received message. For example, when the SquidexFormField receives a message with the type valueChanged, the value property is updated. The SquidexFormField class is for example used in the editor-editorjs.html file, which can be accessed via the public wwwroot folder. It uses the onValueChanged method to register a callback function, which passes the value provided from the message event to the editor.render. Passing an attacker-controlled value to this function introduces a Cross-Site Scripting (XSS) vulnerability.

Nov 7, 2023Squidex is an open source headless CMS and content management hub.CVE-2023-46744 · Other software · Squidex · reported by GitHubMedium 5.4
Squidex is an open source headless CMS and content management hub. In affected versions a stored Cross-Site Scripting (XSS) vulnerability enables privilege escalation of authenticated users. The SVG element filtering mechanism intended to stop XSS attacks through uploaded SVG images, is insufficient resulting to stored XSS attacks. Squidex allows the CMS contributors to be granted the permission of uploading an SVG asset. When the asset is uploaded, a filtering mechanism is performed to validate that the SVG does not contain malicious code. The validation logic consists of traversing the HTML nodes in the DOM. In order for the validation to succeed, 2 conditions must be met: 1. No HTML tags included in a "blacklist" called "InvalidSvgElements" are present. This list only contains the element "script". and 2. No attributes of HTML tags begin with "on" (i.e. onerror, onclick) (line 65). If either of the 2 conditions is not satisfied, validation fails and the file/asset is not uploaded. However it is possible to bypass the above filtering mechanism and execute arbitrary JavaScript code by introducing other HTML elements such as an <iframe> element with a "src" attribute containing a "
