Description

This security bulletin contains information about 1 vulnerability.

1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-75140)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to allocation of resources without limits or throttling in the XmlTreeBuilder namespace scope tracking when parsing untrusted XML input. A remote attacker can supply a deeply nested XML document with uniquely named namespace declarations to cause a denial of service.

Parsing documents with many nested namespace bindings grows quadratically in time and retained memory.

Remediation

Install update from vendor's website.
