…evExpress#743) PostCSS <= 8.5.11 dereferences attacker-controlled paths from `sourceMappingURL` CSS comments, enabling arbitrary file read and information disclosure (CVE-2026-45623). Re-point the workspace override to `postcss@<=8.5.11: ^8.5.12` and raise the postcss dependency in devextreme-themebuilder (^8.5.12) and devextreme-scss (8.5.15) above the vulnerable range.
