CVE-2021-43846Public exploitNetwork attack vector

Cart modification via missing CSRF verification

Published Dec 20, 2021 · Updated Aug 4, 2024

CSRF in Solidus solidus_frontend before 2.11.14, 3.0.0 through 3.0.4, and 3.1.0 through 3.1.4 allows remote attackers to add cart items. Spree::OrdersController#populate explicitly skips Rails authenticity-token verification, so it accepts forged POST requests carrying a victim's session cookie. A victim must visit an attacker-controlled site while holding a store session; the published impact is limited to cart modification, with no purchase completion reported.
