SCA: security update for dompurify (GHSA-vxr8-fq34-vvx9)

medium Tenable Self-Hosted Container Security Plugin ID 443230

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- DOMPurify 3.0.0 before 3.4.9 does not reset the retained Trusted Types policy when clearConfig() is
called, so a DOMPurify instance reused across trust boundaries stays bound to a previously supplied
TRUSTED_TYPES_POLICY. A later caller that requests RETURN_TRUSTED_TYPE output receives a TrustedHTML
object created by the old (potentially unsafe) policy rather than a clean default, which can lead to
script execution at a Trusted Types sink. Passing TRUSTED_TYPES_POLICY: null on the later call also does
not clear the retained policy. (CVE-2026-65899)

Solution

Update the dompurify library and its related packages to version 3.4.9 or later.
