Strapi is an open-source content management system. By combining two vulnerabilities (an `Open Redirect` and `session token sent as URL query parameter`) in @strapi/plugin-users-permissions before version 4.24.2, is its possible of an unauthenticated attacker to bypass authentication mechanisms and retrieve the 3rd party tokens. The attack requires user interaction (one click). Unauthenticated attackers can leverage two vulnerabilities to obtain an 3rd party token and the bypass authentication of Strapi apps. Users should upgrade @strapi/plugin-users-permissions to version 4.24.2 to receive a patch.

Strapi is an open-source content management system. Prior to version 4.22.0, a denial-of-service vulnerability is present in the media upload process causing the server to crash without restarting, affecting either development and production environments. Usually, errors in the application cause it to log the error and keep it running for other clients. This behavior, in contrast, stops the server execution, making it unavailable for any clients until it's manually restarted. Any user with access to the file upload functionality is able to exploit this vulnerability, affecting applications running in both development mode and production mode as well. Users should upgrade @strapi/plugin-upload to version 4.22.0 to receive a patch.

Strapi is an open-source content management system. Prior to version 4.19.1, a super admin can create a collection where an item in the collection has an association to another collection. When this happens, another user with Author Role can see the list of associated items they did not create. They should see nothing but their own items they created not all items ever created. Users should upgrade @strapi/plugin-content-manager to version 4.19.1 to receive a patch.

strapi is an open-source headless CMS. Versions prior to 4.13.1 did not properly restrict write access to fielded marked as private in the user registration endpoint. As such malicious users may be able to errantly modify their user records. This issue has been addressed in version 4.13.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Strapi is the an open-source headless content management system. Prior to version 4.12.1, there is a rate limit on the login function of Strapi's admin screen, but it is possible to circumvent it. Therefore, the possibility of unauthorized login by login brute force attack increases. Version 4.12.1 has a fix for this issue.

Strapi is the an open-source headless content management system. Prior to version 4.12.1, field level permissions are not respected in the relationship title. If an actor has relationship title and the relationship shows a field they don't have permission to see, the field will still be visible. Version 4.12.1 has a fix for this issue.

Strapi is an open-source headless content management system. Prior to version 4.11.7, an unauthorized actor can get access to user reset password tokens if they have the configure view permissions. The `/content-manager/relations` route does not remove private fields or ensure that they can't be selected. This issue is fixed in version 4.11.7.

Strapi is an open-source headless content management system. Prior to version 4.10.8, it is possible to leak private fields if one is using the `t(number)` prefix. Knex query allows users to change the default prefix. For example, if someone changes the prefix to be the same as it was before or to another table they want to query, the query changes from `password` to `t1.password`. `password` is protected by filtering protections but `t1.password` is not protected. This can lead to filtering attacks on everything related to the object again, including admin passwords and reset-tokens. Version 4.10.8 fixes this issue.

Strapi is an open-source headless content management system. Prior to version 4.10.8, anyone (Strapi developers, users, plugins) can make every attribute of a Content-Type public without knowing it. The vulnerability only affects the handling of content types by Strapi, not the actual content types themselves. Users can use plugins or modify their own content types without realizing that the `privateAttributes` getter is being removed, which can result in any attribute becoming public. This can lead to sensitive information being exposed or the entire system being taken control of by an attacker(having access to password hashes). Anyone can be impacted, depending on how people are using/extending content-types. If the users are mutating the content-type, they will not be affected. Version 4.10.8 contains a patch for this issue.

Strapi through 4.5.5 allows attackers (with access to the admin panel) to discover sensitive user details by exploiting the query filter. The attacker can filter users by columns that contain sensitive information and infer a value from API responses. If the attacker has super admin access, then this can be exploited to discover the password hash and password reset token of all users. If the attacker has admin panel access to an account with permission to access the username and email of API users with a lower privileged role (e.g., Editor or Author), then this can be exploited to discover sensitive information for all API users but not other admin accounts.
