Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Open WebUI, versions before 0.3.16, performs sensitive actions such as deleting and resetting data through GET requests, which makes it vulnerable to cross-site request forgery. An attacker can get a logged-in user to trigger these actions by luring them to a malicious site or link, affecting availability and integrity. Upgrade to version 0.3.16 or later.
