A remote attacker could exploit inefficient regular expression (regex) parsing when processing hex numeric character references (\u0026#x...;) in XML documents. This could lead to a Regular Expression Denial of Service (ReDoS), impacting the availability of the affected component. This issue is the result of an incomplete fix for CVE-2024-49761.",
