The Giveaways and Contests by RafflePress WordPress plugin suffers from a stored cross-site scripting vulnerability due to insufficient input sanitization and output escaping of the 'parent_url' parameter. This flaw allows unauthenticated attackers to inject arbitrary web scripts that execute in the context of users visiting the injected pages. The vulnerability affects all versions up to and including 1.12.5. The CVSS 3.1 base score is 7.2, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impacts on confidentiality and integrity with scope changed.

Successful exploitation enables an attacker to execute arbitrary scripts in the context of users visiting the affected pages, potentially leading to theft of user credentials, session hijacking, or other malicious actions impacting confidentiality and integrity. There is no impact on availability. No known exploits in the wild have been reported to date.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or removing the vulnerable plugin to prevent exploitation. Monitoring vendor channels for updates is recommended.
