CVE-2023-3627Network attack vector

Unauthorized changes via GET CSRF bypass

Published Jul 11, 2023 · Updated Oct 30, 2024

Cross-Site Request Forgery in SuiteCRM before 8.3.1 allows remote attackers to change data through a victim's authenticated browser. CSRFValidationListener skipped validation for GET requests, allowing crafted links or resources to trigger state-changing endpoints without a CSRF token. Exploitation requires a logged-in victim to load attacker-controlled content; resulting confidentiality, integrity, or availability impact depends on the endpoint reached.
