Cross-site request forgery via content-type mismatch
Published Jan 29, 2020 · Updated Aug 4, 2024
CSRF in Webargs 5.0.0 through 5.5.2 and 6.0.0b1 through 6.0.0b3 allows remote attackers to submit cross-domain JSON requests. The Flask parser accepts a syntactically valid JSON body without first requiring an application/json Content-Type header. Exploitation requires a victim to visit attacker-controlled content while authenticated to an affected application, enabling state-changing requests in that victim's session.
