Incorrect authorization in the module allows forceful browsing. The module fails to sufficiently verify permissions for creating, viewing, and updating the parent webform when accessing REST endpoints. This issue requires the attacker to already possess permissions to use the REST resource.

An attacker with appropriate JSON:API write permissions could potentially inject a malicious payload in certain rare circumstances, leading to PHP Object Injection. PHP Object Injection occurs when untrusted input is used to instantiate objects, which can allow an attacker to execute arbitrary code or manipulate application logic. This issue is exploitable only if a site uses an entity reference field type that stores a serialized property and has enabled write access for JSON:API, which is read-only by default.

Drupal core contains a gadget chain, which is a sequence of existing code fragments that can be leveraged during the deserialization of untrusted data. While this issue is not directly exploitable, it can serve as a vector to achieve remote code execution or SQL injection if a separate vulnerability allows an attacker to pass unsafe input to the `unserialize()` function.

An unauthenticated SQL injection flaw exists in the database abstraction API of Drupal Core, specifically within the PostgreSQL `EntityQuery` condition handler. The issue occurs when attacker-controlled PHP array keys, such as `filter[...][condition][value][malicious key]`, are concatenated directly into SQL identifiers without proper sanitization. This vulnerability exclusively affects sites using PostgreSQL databases. Remote anonymous users can exploit this to achieve full database access, exfiltrate sensitive data, escalate privileges to Administrator, and potentially execute arbitrary shell commands on the host server via Remote Code Execution (RCE) if database permissions are misconfigured (e.g., allowing `COPY FROM PROGRAM`). Over 15,000 attack probes against approximately 6,000 sites across 65 countries have been detected, with gaming and financial services being primary targets.

Drupal core's jQuery integration for AJAX modal dialog boxes does not sufficiently sanitize certain options, which can lead to cross-site scripting (XSS), a flaw where malicious scripts are injected into trusted websites.

Drupal core contains an improperly controlled modification of dynamically-determined object attributes, leading to Object Injection. This allows for potential manipulation of objects within the system.

Name of the Vulnerable Software and Affected Versions: Drupal Layout Builder Advanced Permissions versions 0.0.0 through 2.1.9 Description: Missing authorization allows forceful browsing in Drupal Layout Builder Advanced Permissions. Recommendations: Update to version 2.2.0 or later.
