Vulnerability identifier: #VU29137
Vulnerability risk: Medium
Exploitation vector: Network
Exploit availability: No
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing JSON:API PATCH requests. A remote attacker can pass specially crafted input to the application and bypass implemented security restrictions.
By default, JSON:API works in a read-only mode which makes it impossible to exploit the vulnerability. Only sites that have the
read_only set to
jsonapi.settings config are vulnerable.
Install updates from vendor's website.

Drupal: 9.0.0 - 9.0.0 rc1, 8.9.0 - 8.9.0 rc1, 8.8.0 - 8.8.7
