Description
WordPress Plugin InPost Gallery is prone to multiple vulnerabilities, including cross-site scripting and local file inclusion vulnerabilities. Exploiting these issues may allow an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, allowing the attacker to steal cookie-based authentication credentials or to obtain sensitive information that could aid in further attacks. WordPress Plugin InPost Gallery version 2.1.2 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.1.2.1 or latest
