Open source machine learning framework. A vulnerability has been identified in Rasa that enables an attacker who has the ability to load a maliciously crafted model remotely into a Rasa instance to achieve Remote Code Execution. The prerequisites for this are: 1. The HTTP API must be enabled on the Rasa instance eg with `--enable-api`. This is not the default configuration. 2. For unauthenticated RCE to be exploitable, the user must not have configured any authentication or other security controls recommended in our documentation. 3. For authenticated RCE, the attacker must posses a valid authentication token or JWT to interact with the Rasa API. This issue has been addressed in rasa version 3.6.21 and all users are advised to upgrade. Users unable to upgrade should ensure that they require authentication and that only trusted users are given access.

Nextcloud Server is a self hosted personal cloud system. After a user received a share with some files inside being blocked by the files access control, the user would still be able to copy the intermediate folder inside Nextcloud allowing them to afterwards potentially access the blocked files depending on the user access control rules. It is recommended that the Nextcloud Server is upgraded to 27.1.9, 28.0.5 or 29.0.0 and Nextcloud Enterprise Server is upgraded to 21.0.9.18, 22.2.10.23, 23.0.12.18, 24.0.12.14, 25.0.13.9, 26.0.13.3, 27.1.9, 28.0.5 or 29.0.0.

Nextcloud Server is a self hosted personal cloud system. After receiving a "Files drop" or "Password protected" share link a malicious user was able to download attachments that are referenced in Text files without providing the password. It is recommended that the Nextcloud Server is upgraded to 28.0.11, 29.0.8 or 30.0.1 and Nextcloud Enterprise Server is upgraded to 25.0.13.13, 26.0.13.9, 27.1.11.9, 28.0.11, 29.0.8 or 30.0.1.

user_oidc app is an OpenID Connect user backend for Nextcloud. A malicious user could send a malformed login link that would redirect the user to a provided URL after successfully authenticating. It is recommended that the Nextcloud User OIDC app is upgraded to 6.1.0.

Nextcloud Tables allows users to to create tables with individual columns. By directly specifying the ID of a table or view, a malicious user could blindly insert new rows into tables they have no access to. It is recommended that the Nextcloud Tables is upgraded to 0.8.0.

The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server with your computer. The Desktop client did not stop with an error but allowed by-passing the signature validation, if a manipulated server sends an empty initial signature. It is recommended that the Nextcloud Desktop client is upgraded to 3.14.2 or later.

Nextcloud Mail is the mail app for Nextcloud, a self-hosted productivity platform. The Nextcloud mail app incorrectly allowed attaching shared files without download permissions as attachments. This allowed users to send them the files to themselves and then downloading it from their mail clients. It is recommended that the Nextcloud Mail is upgraded to 2.2.10, 3.6.2 or 3.7.2.

Nextcloud Mail is the mail app for Nextcloud, a self-hosted productivity platform. When a user is trying to set up a mail account with an email address like user@example.tld that does not support auto configuration, and an attacker managed to register autoconfig.tld, the used email details would be send to the server of the attacker. It is recommended that the Nextcloud Mail app is upgraded to 1.14.6, 1.15.4, 2.2.11, 3.6.3, 3.7.7 or 4.0.0.

Nextcloud Server is a self hosted personal cloud system. After setting up a user or administrator defined external storage with fixed credentials, the API returns them and adds them into the frontend again, allowing to read them in plain text when an attacker already has access to an active session of a user. It is recommended that the Nextcloud Server is upgraded to 28.0.12, 29.0.9 or 30.0.2 and Nextcloud Enterprise Server is upgraded to 25.0.13.14, 26.0.13.10, 27.1.11.10, 28.0.12, 29.0.9 or 30.0.2.
