What is CVE-2025-40703?

OpenAtlas v8.9.0 contains a Cross-Site Scripting vulnerability that arises from insufficient validation of user inputs. When an attacker sends specially crafted POST requests, they can exploit this flaw through the '/insert/group' endpoint, particularly targeting 'name' and 'alias-0' parameters.
