Token theft via unvalidated carousel URLs
Published Dec 16, 2024 · Updated Dec 17, 2024
Open redirect in UJCMS 9.6.3 allows remote authenticated users to send visitors to attacker-controlled sites through carousel items. The block-item creation path at /cp/#/content/block-item stores arbitrary destination URLs without validating or restricting their domains, and the front end renders those values as clickable carousel links. Exploitation requires content-management access and a visitor click; the destination page can read and exfiltrate the jwt-access-token because the cookie lacks HttpOnly.
