The whiletrue Most And Least Read Posts Widget (version ≤ 2.5.20) contains a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers with low privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability. The CVSS vector indicates network attack vector, low attack complexity, privileges required, user interaction required, and scope change with partial impacts on confidentiality, integrity, and availability. No patch or vendor advisory information is provided, and no known exploits exist in the wild.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to data disclosure, modification, or disruption of service. The CVSS score of 6.5 reflects a medium severity with impacts on confidentiality, integrity, and availability. However, exploitation requires user interaction and some privileges, limiting the ease of attack.

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 removing the affected widget to prevent exploitation. Monitor vendor channels for updates or patches addressing this vulnerability.
