    High [CVE-2026-15928] Cross-Site Scripting in error page component

    CVE-2026-15928Source published Source updated

    XMLRPC-C Library versions 1.07 through 1.67.01 are vulnerable to a reflected cross-site scripting (XSS) vulnerability in the error page component. A remote attacker could exploit this by tricking a user into clicking a specially crafted link. Successful exploitation could lead to the execution of malicious scripts in the user's browser, potentially resulting in information disclosure or session hijacking. This reflected cross-site scripting (XSS) vulnerability relies entirely on client-side interaction through a web browser. If executed, the script runs within the context of the user's browser session, making sensitive session tokens or client-side data accessible to the attacker. While external CVSSv4 scoring rates this flaw to an 8.2 High, Red Hat bounds the severity to CVSS 7.4 based…

    Mitigation guidance
    • To mitigate this issue, ensure that applications utilizing the XMLRPC-C library do not directly expose its error pages to end-users via a web browser. Configure web servers or application frontends to intercept and sanitize or replace error responses originating from XMLRPC-C before they are rendered client-side. Alternatively, restrict XMLRPC-C deployments to backend services that do not present error output in a user-facing web interface.
