user_oidc app is an OpenID Connect user backend for Nextcloud. Authentication can be broken/bypassed in user_oidc app. It is recommended that the Nextcloud user_oidc app is upgraded to 1.3.2

Nextcloud server is an open source, self hosted personal cloud. Nextcloud supports rendering image previews for user provided file content. For some image types, the Nextcloud server was invoking a third-party library that wasn't suited for untrusted user-supplied content. There are several security concerns with passing user-generated content to this library, such as Server-Side-Request-Forgery, file disclosure or potentially executing code on the system. The risk depends on your system configuration and the installed library version. It is recommended that the Nextcloud Server is upgraded to 20.0.12, 21.0.4 or 22.1.0. These versions do not use this library anymore. As a workaround users may disable previews by setting `enable_previews` to `false` in `config.php`.

Nextcloud server before 19.0.11, 20.0.10, 21.0.2 is vulnerable to brute force attacks due to lack of inclusion of IPv6 subnets in rate-limiting considerations. This could potentially result in an attacker bypassing rate-limit controls such as the Nextcloud brute-force protection.

NextcloudPi is a ready to use image for Virtual Machines, Raspberry Pi, Odroid HC1, Rock64 and other boards. A command injection vulnerability in NextCloudPi allows command execution as the root user via the NextCloudPi web-panel. Due to a security misconfiguration this can be used by anyone with access to NextCloudPi web-panel, no authentication is required. It is recommended that the NextCloudPi is upgraded to 1.53.1.

Nextcloud Server provides data storage for Nextcloud, an open source cloud platform. In Nextcloud Server prior to versions 26.0.9 and 27.1.4; as well as Nextcloud Enterprise Server prior to versions 23.0.12.13, 24.0.12.9, 25.0.13.4, 26.0.9, and 27.1.4; when a (reverse) proxy is configured as trusted proxy the server could be tricked into reading a wrong remote address for an attacker, allowing them executing authentication attempts than intended. Nextcloud Server versions 26.0.9 and 27.1.4 and Nextcloud Enterprise Server versions 23.0.12.13, 24.0.12.9, 25.0.13.4, 26.0.9, and 27.1.4 contain a patch for this issue. No known workarounds are available.

Nextcloud Mail app versions 2.2.8 and 3.3.0 contain a patch for this issue. As a workaround, disable the mail app.

Nextcloud Mail is an email application for the nextcloud personal cloud product. Affected versions shipped with a CSS minifier on the path `./vendor/cerdic/css-tidy/css_optimiser.php`. Access to the minifier is unrestricted and access may lead to Server-Side Request Forgery (SSRF). It is recommendet to upgrade to Mail 1.12.7 or Mail 1.13.6. Users unable to upgrade may manually delete the file located at `./vendor/cerdic/css-tidy/css_optimiser.php`

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.

An SQL Injection in the Nextcloud Lookup-Server < v0.3.0 (running on https://lookup.nextcloud.com) caused unauthenticated users to be able to execute arbitrary SQL commands.

Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.011, and 21.0.3, webauthn tokens were not deleted after a user has been deleted. If a victim reused an earlier used username, the previous user could gain access to their account. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds.

Nextcloud server is an open source, self hosted personal cloud. In affected versions an attacker is able to bypass Two Factor Authentication in Nextcloud. Thus knowledge of a password, or access to a WebAuthN trusted device of a user was sufficient to gain access to an account. It is recommended that the Nextcloud Server is upgraded to 20.0.12, 21.0.4 or 22.1.0. There are no workaround for this vulnerability.

Bypass lock protection in the Nextcloud Android app prior to version 3.6.1 allows accessing the files when repeatedly opening and closing the app in a very short time.

This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.

VMware Cloud Director Appliance contains an authentication bypass vulnerability in case VMware Cloud Director Appliance was upgraded to 10.5 from an older version. On an upgraded version of VMware Cloud Director Appliance 10.5, a malicious actor with network access to the appliance can bypass login restrictions when authenticating on port 22 (ssh) or port 5480 (appliance management console) . This bypass is not present on port 443 (VCD provider and tenant login). On a new installation of VMware Cloud Director Appliance 10.5, the bypass is not present. VMware Cloud Director Appliance is impacted since it uses an affected version of sssd from the underlying Photon OS. The sssd issue is no longer present in versions of Photon OS that ship with sssd-2.8.1-11 or higher (Photon OS 3) or sssd-2.8.2-9 or higher (Photon OS 4 and 5).

The WordPress & WooCommerce Affiliate Program plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 8.4.1. This is due to the rtwwwap_login_request_callback() function not properly validating a user's identity prior to authenticating them to the site. This makes it possible for unauthenticated attackers to log in as any user, including administrators, granted they have access to the administrator's email.

Enterprise Cloud Database from Ragic does not authenticate access to specific functionality, allowing unauthenticated remote attackers to use this functionality to obtain any user's session cookie.

The variable import endpoint was not protected by authentication in Airflow >=2.0.0, <2.1.3.

This issue affects Apache Airflow >=2.0.0, <2.1.3.

The LatePoint plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.0.12. This is due to insufficient verification on the user being supplied during the booking customer step. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id. Note that logging in as a WordPress user is only possible if the "Use WordPress users as customers" setting is enabled, which is disabled by default. The vulnerability is partially patched in version 5.0.12 and fully patched in version 5.0.13.

The WooCommerce Photo Reviews Premium plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.3.13.2. This is due to the plugin not properly validating what user transient is being used in the login() function and not properly verifying the user's identity. This makes it possible for unauthenticated attackers to log in as user that has dismissed an admin notice in the past 30 days, which is often an administrator. Alternatively, a user can log in as any user with any transient that has a valid user_id as the value, though it would be more difficult to exploit this successfully.

The WooCommerce - Social Login plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.7.5. This is due to the use of loose comparison of the activation code in the 'woo_slg_confirm_email_user' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the userID. This requires the email module to be enabled.

The Jupiter X Core plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 4.7.5. This is due to improper authentication via the Social Login widget. This makes it possible for unauthenticated attackers to log in as the first user to have logged in with a social media account, including administrator accounts. Attackers can exploit the vulnerability even if the Social Login element has been disabled, as long as it was previously enabled and used. The vulnerability was partially patched in version 4.7.5, and fully patched in version 4.7.8.

Advantech iView, versions 5.6 and prior, has an improper authentication for critical function (CWE-306) issue.
