CVE-2024-9378 is a reflected cross-site scripting vulnerability in the YML for Yandex Market plugin for WordPress, specifically affecting the 'page' parameter. The vulnerability exists due to improper neutralization of input during web page generation, allowing injection of arbitrary web scripts. This affects all versions up to and including 4.7.2. The CVSS 3.1 base score is 6.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no impact on availability. No patch or remediation details are currently provided.

Successful exploitation allows unauthenticated attackers to execute arbitrary scripts in the context of a victim user's browser, potentially leading to information disclosure or manipulation of user interactions within the affected site. The impact is limited to confidentiality and integrity with no availability impact. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or restricting access to the vulnerable plugin or parameter if possible. Applying web application firewall (WAF) rules to detect and block malicious input targeting the 'page' parameter may provide temporary mitigation.
