CVE-2023-7273 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. Cross site request forgery in Kiteworks OwnCloud allows an unauthenticated attacker to forge requests. If a request has no Authorization header, it is created with an empty string as value by a rewrite rule. The CSRF check is done by comparing the header value to null, meaning that the existing CSRF check is bypassed in this case. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
