OpenRefine is a free, open source tool for working with messy data. Prior to version 3.8.3, lack of cross-site request forgery protection on the `preview-expression` command means that visiting a malicious website could cause an attacker-controlled expression to be executed. The expression can contain arbitrary Clojure or Python code. The attacker must know a valid project ID of a project that contains at least one row, and the attacker must convince the victim to open a malicious webpage. Version 3.8.3 fixes the issue.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
