The vulnerability CVE-2026-22491 affects the wphocus My auctions allegro plugin (versions up to 3.6.35) and is classified as a reflected cross-site scripting (XSS) issue. It occurs due to improper neutralization of user input during web page generation, enabling attackers to inject malicious scripts that execute when a victim visits a crafted URL. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at low levels.

Successful exploitation of this vulnerability can allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions that affect confidentiality, integrity, and availability at a low level. The scope change in the CVSS vector indicates that the vulnerability can impact resources beyond the initially vulnerable component.
