CWE-837

While assignment of a user to a team (bracket) in CTFd should be possible only once, at the registration, a flaw in logic implementation allows an authenticated user to reset it's bracket and then pick a new one, joining another team while a competition is already ongoing. This issue impacts releases from 3.7.0 up to 3.7.4 and was addressed by pull request 2636 https://github.com/CTFd/CTFd/pull/2636  included in 3.7.5 release.

A vulnerability classified as problematic has been found in Thecosy IceCMS 2.0.1. This affects an unknown part of the file /WebResource/resource of the component Love Handler. The manipulation leads to improper enforcement of a single, unique action. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-247887.

A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.

A vulnerability classified as problematic has been found in Thecosy IceCMS 2.0.1. Affected is an unknown function of the file /WebArticle/articles/ of the component Like Handler. The manipulation leads to improper enforcement of a single, unique action. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-246438 is the identifier assigned to this vulnerability.

Tokens in CTFd used for account activation and password resetting can be used interchangeably for these operations. When used, they are sent to the server as a GET parameter and they are not single use, which means, that during token expiration time an on-path attacker might reuse such a token to change user's password and take over the account. Moreover, the tokens also include base64 encoded user email. This issue impacts releases up to 3.7.4 and was addressed by pull request 2679 https://github.com/CTFd/CTFd/pull/2679  included in 3.7.5 release.

A vulnerability was found in Thecosy IceCMS 2.0.1. It has been rated as problematic. This issue affects some unknown processing of the file /Websquare/likeClickComment/ of the component Comment Like Handler. The manipulation leads to improper enforcement of a single, unique action. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The identifier VDB-246617 was assigned to this vulnerability.

In lunary-ai/lunary before version 1.6.3, the application allows the creation of evaluators without enforcing a unique constraint on the combination of projectId and slug. This allows an attacker to overwrite existing data by submitting a POST request with the same slug as an existing evaluator. The lack of database constraints or application-layer validation to prevent duplicates exposes the application to data integrity issues. This vulnerability can result in corrupted data and potentially malicious actions, impairing the system's functionality.

A vulnerability classified as problematic was found in phpkobo Ajax Poll Script 3.18. Affected by this vulnerability is an unknown functionality of the file ajax-poll.php of the component Poll Handler. The manipulation leads to improper enforcement of a single, unique action. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-240949 was assigned to this vulnerability.

Grav is a file-based Web platform. Prior to 2.0.0-beta.2, a business logic vulnerability in the Grav Admin Panel allows a low-privileged user (with only user creation permissions) to overwrite existing accounts, including the primary administrator. By creating a new user with a username that already exists, the system updates the existing account's metadata and permissions instead of rejecting the request. This leads to a Denial of Service (DoS) on administrative functions and Privilege De-escalation of the root account. This vulnerability is fixed in 2.0.0-beta.2.

A hidden field manipulation vulnerability was identified in Issuetrak version 17.1 that could be triggered by an authenticated user.  When an authenticated user submits a ticket, the request can be intercepted and subsequently modified by using a proxy.  The ticket requester can be changed from the original requester to another user in the same application, which the application then accepts.

Tor before 0.4.9.7, when circuit queue memory pressure exists, can experience a client crash because of a double close of a circuit, aka TROVE-2026-009.

The Matrix specification before 1.16 (i.e., with a room version before 12) lacks create event uniqueness.

Improper action enforcement in certain Zoom Workplace Clients for Windows may allow an unauthenticated user to conduct a disclosure of information via network access.

InventoryGui is a library for creating chest GUIs for Bukkit/Spigot plugins. Versions 1.6.3-SNAPSHOT and earlier contain a vulnerability where GUIs using GuiStorageElement can allow item duplication when the experimental Bundle item feature is enabled on the server. The vulnerability is resolved in version 1.6.4-SNAPSHOT.

InventoryGui is a library for creating chest GUIs for Bukkit/Spigot plugins. Versions 1.6.1-SNAPSHOT and earlier contain a vulnerability where any plugin using the `GuiStorageElement can allow item duplication when the experimental Bundle item feature is enabled on the server. The vulnerability is resolved in version 1.6.2-SNAPSHOT.

InventoryGui is a library for creating chest GUIs for Bukkit/Spigot plugins. Versions before 1.6.5 contain a vulnerability where any plugin using a GUI with the GuiStorageElement and allows taking out items out of that element can allow item duplication when the experimental Bundle item feature is enabled on the server. The vulnerability is resolved in version 1.6.5.
