CVE-2026-22491 describes a Reflected Cross-Site Scripting (XSS) vulnerability discovered in the My auctions allegro free edition WordPress plugin. This vulnerability allows attackers to inject malicious scripts into web pages, potentially leading to unauthorized access and data theft. The vulnerability affects versions from 0.0.0 up to and including 3.6.35, and a patch is expected to be released by the vendor.
Successful exploitation of CVE-2026-22491 allows an attacker to inject arbitrary JavaScript code into web pages viewed by other users. This can be leveraged to steal session cookies, redirect users to malicious websites, or deface the website. The impact is particularly severe if the plugin is used on sites handling sensitive user data, such as e-commerce platforms or membership sites. An attacker could potentially gain complete control over a user's account or compromise the entire website if they can execute code with administrative privileges. The reflected nature of the XSS means that the attacker needs to trick a user into clicking a malicious link, but the potential impact is still significant.
CVE-2026-22491 was publicly disclosed on 2026-03-25. As of this date, there are no known public exploits or active campaigns targeting this vulnerability. The vulnerability is not currently listed on the CISA KEV catalog. The ease of exploitation (reflected XSS) suggests a potential for opportunistic exploitation if a public proof-of-concept is released.
Websites utilizing the My auctions allegro free edition plugin, particularly those with user input fields or areas where user-generated content is displayed, are at risk. Shared hosting environments where multiple websites share the same server resources are also potentially vulnerable, as a compromise of one site could lead to the compromise of others.
