| CVE-2022-31014 | 1 Nextcloud | 1 Nextcloud Server | 2023-06-29 | 3.5 LOW | 3.5 LOW |
| Nextcloud server is an open source personal cloud server. Affected versions were found to be vulnerable to SMTP command injection. The impact varies based on which commands are supported by the backend SMTP server. However, the main risk here is that the attacker can then hijack an already-authenticated SMTP session and run arbitrary SMTP commands as the email user, such as sending emails to other users, changing the FROM user, and so on. As before, this depends on the configuration of the server itself, but newlines should be sanitized to mitigate such arbitrary SMTP command injection. It is recommended that the Nextcloud Server is upgraded to 22.2.8 , 23.0.5 or 24.0.1. There are no known workarounds for this issue. | |||||
| CVE-2022-24838 | 1 Nextcloud | 1 Calendar | 2023-06-23 | 7.5 HIGH | 9.8 CRITICAL |
| Nextcloud Calendar is a calendar application for the nextcloud framework. SMTP Command Injection in Appointment Emails via Newlines: as newlines and special characters are not sanitized in the email value in the JSON request, a malicious attacker can inject newlines to break out of the `RCPT TO:<BOOKING USER'S EMAIL> ` SMTP command and begin injecting arbitrary SMTP commands. It is recommended that Calendar is upgraded to 3.2.2. There are no workaround available. | |||||
| CVE-2023-33182 | 1 Nextcloud | 1 Contacts | 2023-06-06 | N/A | 4.3 MEDIUM |
| Contacts app for Nextcloud easily syncs contacts from various devices with your Nextcloud and allows editing. The unsanitized SVG is converted to a JavaScript blob (in memory data) that the Avatar can't render. Due to this constellation the missing sanitization does not seem to be exploitable. It is recommended that the Contacts app is upgraded to 5.0.3 or 4.2.4 | |||||
| CVE-2023-33183 | 1 Nextcloud | 1 Calendar | 2023-06-05 | N/A | 4.3 MEDIUM |
| Calendar app for Nextcloud easily sync events from various devices with your Nextcloud. Some internal paths of the website are disclosed when the SMTP server is unavailable. It is recommended that the Calendar app is updated to 3.5.5 or 4.2.3 | |||||
| CVE-2023-31128 | 1 Nextcloud | 1 Cookbook | 2023-06-05 | N/A | 8.8 HIGH |
| NextCloud Cookbook is a recipe library app. Prior to commit a46d9855 on the `master` branch and commit 489bb744 on the `main-0.9.x` branch, the `pull-checks.yml` workflow is vulnerable to command injection attacks because of using an untrusted `github.head_ref` field. The `github.head_ref` value is an attacker-controlled value. Assigning the value to `zzz";echo${IFS}"hello";#` can lead to command injection. Since the permission is not restricted, the attacker has a write-access to the repository. This issue is fixed in commit a46d9855 on the `master` branch and commit 489bb744 on the `main-0.9.x` branch. There is no risk for the user of the app within the NextCloud server. This only affects the main repository and possible forks of it. Those who have forked the NextCloud Cookbook repository should make sure their forks are on the latest version to prevent code injection attacks and similar. | |||||
| CVE-2023-32319 | 1 Nextcloud | 1 Nextcloud Server | 2023-06-03 | N/A | 6.5 MEDIUM |
| Nextcloud server is an open source personal cloud implementation.

| CVE-2023-33184 | 1 Nextcloud | 1 Nextcloud Mail | 2023-06-02 | N/A | 5.3 MEDIUM |
| Nextcloud Mail is a mail app in Nextcloud. A blind SSRF attack allowed to send GET requests to services running in the same web server. It is recommended that the Mail app is update to version 3.02, 2.2.5 or 1.15.3. | |||||
| CVE-2023-32318 | 1 Nextcloud | 1 Nextcloud Server | 2023-06-02 | N/A | 6.7 MEDIUM |
| Nextcloud server provides a home for data. A regression in the session handling between Nextcloud Server and the Nextcloud Text app prevented a correct destruction of the session on logout if cookies were not cleared manually. After successfully authenticating with any other account the previous session would be continued and the attacker would be authenticated as the previously logged in user. It is recommended that the Nextcloud Server is upgraded to 25.0.6 or 26.0.1. | |||||

| CVE-2023-29000 | 1 Nextcloud | 1 Desktop | 2023-04-11 | N/A | 6.5 MEDIUM |
| The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server. Starting with version 3.0.0 and prior to version 3.7.0, by trusting that the server will return a certificate that belongs to the keypair of the user, a malicious server could get the desktop client to encrypt files with a key known to the attacker. This issue is fixed in Nextcloud Desktop 3.7.0. No known workarounds are available. | |||||
| CVE-2023-28997 | 1 Nextcloud | 1 Desktop | 2023-04-10 | N/A | 6.5 MEDIUM |

| CVE-2023-28848 | 1 Nextcloud | 1 User Oidc | 2023-04-10 | N/A | 5.4 MEDIUM |
| user_oidc is the OIDC connect user backend for Nextcloud, an open source collaboration platform. A vulnerability in versions 1.0.0 until 1.3.0 effectively allowed an attacker to bypass the state protection as they could just copy the expected state token from the first request to their second request. Users should upgrade user_oidc to 1.3.0 to receive a patch for the issue. No known workarounds are available. | |||||
| CVE-2023-28834 | 1 Nextcloud | 1 Nextcloud Server | 2023-04-10 | N/A | 4.3 MEDIUM |
| Nextcloud Server is an open source personal cloud server. Nextcloud Server 24.0.0 until 24.0.6 and 25.0.0 until 25.0.4, as well as Nextcloud Enterprise Server 23.0.0 until 23.0.11, 24.0.0 until 24.0.6, and 25.0.0 until 25.0.4, have an information disclosure vulnerability. A user was able to get the full data directory path of the Nextcloud server from an API endpoint. By itself this information is not problematic as it can also be guessed for most common setups, but it could speed up other unknown attacks in the future if the information is known. Nextcloud Server 24.0.6 and 25.0.4 and Nextcloud Enterprise Server 23.0.11, 24.0.6, and 25.0.4 contain patches for this issue. There are no known workarounds. | |||||
| CVE-2023-28645 | 1 Nextcloud | 1 Richdocuments | 2023-04-07 | N/A | 6.5 MEDIUM |
| Nextcloud richdocuments is a Nextcloud app integrating the office suit Collabora Online. In affected versions the secure view feature of the rich documents app can be bypassed by using unprotected internal API endpoint of the rich documents app. It is recommended that the Nextcloud Office app (richdocuments) is upgraded to 8.0.0-beta.1, 7.0.2 or 6.3.2. Users unable to upgrade may mitigate the issue by taking steps to restrict the ability to download documents. This includes ensuring that the `WOPI configuration` is configured to only serve documents between Nextcloud and Collabora. It is highly recommended to define the list of Collabora server IPs as the allow list within the Office admin settings of Nextcloud. | |||||
