Red Hat Product Errata RHSA-2026:61315 - Security Advisory Issued: 2026-08-31 Updated: 2026-08-31 RHSA-2026:61315 - Security Advisory Overview Updated Packages Synopsis Important: xmlrpc-c security update Type/Severity Security Advisory: Important Red Hat Lightspeed patch analysis Identify and remediate systems affected by this advisory. View affected systems Topic An update for xmlrpc-c is now available for Red Hat Enterprise Linux 9.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Description XML-RPC is a remote procedure call (RPC) protocol that uses XML to encode its calls and HTTP as a transport mechanism. The xmlrpc-c packages provide a network protocol to allow a client program to make a simple RPC (remote procedure call) over the Internet. It converts an RPC into an XML document, sends it to a remote server using HTTP, and gets back the response in XML. Security Fix(es): xmlrpc-c: XMLRPC-C Library: Cross-Site Scripting in error page component (CVE-2026-15928) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
