This vulnerability (CVE-2026-41557) affects PressLayouts Kapee and is classified as CWE-79: Improper Neutralization of Input During Web Page Generation, commonly known as Cross-Site Scripting (XSS). It allows unauthenticated attackers to inject malicious scripts into web pages viewed by other users. The CVSS 3.1 score is 7.1 (high), with attack vector network, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability rated low to low and low respectively. The affected versions are all versions prior to 1.7.1, though the input data does not explicitly list affected versions, the description states "Kapee < 1.7.1". There is no vendor advisory or patch link provided, and the remediation level is not specified.

Successful exploitation of this vulnerability can allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to partial disclosure of sensitive information, modification of data, and disruption of service availability. The CVSS vector indicates low confidentiality, integrity, and availability impacts, but the scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch is currently documented, users should monitor vendor communications for updates. Until a patch is available, consider applying web application firewall (WAF) rules to detect and block XSS attempts if feasible.
