The CVE associated with this bug was revoked. Please refer to the following: https://github.com/cure53/DOMPurify/issues/1102 https://security.snyk.io/vuln/SNYK-JS-DOMPURIFY-10176060 Nextcloud 29 has reached EOL and upstream will consequently not provide future updates. Their integrity checker hashes all files in the tarball, which complicates any attempt to patch the source during build. Consequently, I will not update dompurify for Nextcloud 29 at this time, since this has been determined, from the link above, not to be a legitimate CVE.
