Deserialization of Untrusted Data vulnerability in Drupal Core allows Object Injection.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 contains a chain of methods that is exploitable when an insecure deserialization vulnerability exists on the site. This so-called gadget chain presents no direct threat but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability.

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.
