CVE-2026-1841 is a stored cross-site scripting vulnerability in the PixelYourSite WordPress plugin affecting all versions up to 11.2.0. It arises from improper neutralization of input during web page generation, specifically in the 'pysTrafficSource' and 'pys_landing_page' parameters. This allows unauthenticated attackers to inject malicious scripts that execute in the context of users visiting the compromised pages. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 7.2, indicating high severity. No patch or official fix information is provided in the available data, and no known exploits have been observed in the wild.

Successful exploitation enables an unauthenticated attacker to perform stored cross-site scripting attacks, potentially leading to the execution of arbitrary scripts in users' browsers. This can result in information disclosure or session hijacking but does not impact availability. The CVSS vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and scope change, with low confidentiality and integrity impacts and no availability impact.

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 affected plugin parameters or applying web application firewall rules to block malicious input targeting 'pysTrafficSource' and 'pys_landing_page'. Monitor vendor channels for updates and apply official patches once released.
