Generation of Error Message Containing Sensitive Information
In certain scenarios, Drupal's JSON:API module will output error backtraces. With some configurations, this may cause sensitive information to be cached and made available to anonymous users, leading to privilege escalation.

This vulnerability only affects sites with the JSON:API module enabled, and can be mitigated by uninstalling JSON:API.

The core REST and contributed GraphQL modules are not affected.

Drupal core contains a potential PHP Object Injection vulnerability that (if combined with another exploit) could lead to Artbitrary File Deletion. It is not directly exploitable.

This issue is mitigated by the fact that in order to be exploitable, a separate vulnerability must be present that allows an attacker to pass unsafe input to `unserialize()`. There are no such known exploits in Drupal core.

To help protect against this vulnerability, types have been added to properties in some of Drupal core's classes. If an application extends those classes, the same types may need to be specified on the subclass to avoid a `TypeError`.

This issue affects Drupal Core: from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.

Drupal Core Cross-Site Scripting (XSS) Vulnerability
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Drupal Drupal core allows Cross-Site Scripting (XSS).This issue affects Drupal core: from 8.0.0 before 10.3.14, from 10.4.0 before 10.4.5, from 11.0.0 before 11.0.13, from 11.1.0 before 11.1.5.

Drupal Core Vulnerable to Forceful Browsing
Incorrect Authorization vulnerability in Drupal core allows Forceful Browsing.This issue affects Drupal core: from 8.0.0 before 10.3.13, from 10.4.0 before 10.4.3, from 11.0.0 before 11.0.12, from 11.1.0 before 11.1.3.

Drupal core Denial of Service vulnerability
The Comment module allows users to reply to comments. In certain cases, an attacker could make comment reply requests that would trigger a denial of service (DOS).

Sites that do not use the Comment module are not affected.

Drupal Core Improperly Controlled Modification of Dynamically-Determined Object Attributes Vulnerability
Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Drupal Drupal core allows Object Injection.This issue affects Drupal core: from 8.0.0 before 10.3.13, from 10.4.0 before 10.4.3, from 11.0.0 before 11.0.12, from 11.1.0 before 11.1.3.

Drupal Core Cross-Site Scripting (XSS)
Drupal uses JavaScript to render status messages in some cases and configurations. In certain situations, the status messages are not adequately sanitized. This issue affects Drupal Core: from 8.8.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.

Drupal core contains a potential PHP Object Injection vulnerability that (if combined with another exploit) could lead to Remote Code Execution. It is not directly exploitable.

This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to `unserialize()`. There are no such known exploits in Drupal core.

To help protect against this potential vulnerability, some additional checks have been added to Drupal core's database code. If you use a third-party database driver, check the release notes for additional configuration steps that may be required in certain cases. 

This issue affects Drupal Core: from 7.0 before 7.102, from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9.
