CVE-2024-11807 is a reflected Cross-Site Scripting vulnerability in the calliko NPS computy WordPress plugin affecting all versions up to 2.8.0. The issue stems from improper neutralization of input during web page generation, specifically in the 'data1' and 'data2' parameters. Attackers can exploit this by injecting malicious scripts that execute in the context of a victim's browser when they click on a crafted link. The vulnerability requires no privileges but does require user interaction. The CVSS 3.1 base score is 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, scope changed, and low impact on confidentiality and integrity, with no impact on availability.

Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the context of the victim'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. The vulnerability requires user interaction to trigger.

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 NPS computy plugin or applying custom input sanitization and output escaping for the 'data1' and 'data2' parameters. Monitor vendor channels for updates and apply patches promptly once available.
