Node postcss: PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. (CVE-2026-45623)CVE-2026-45623 0 A vulnerability in node-postcss versions 8.5.11 and earlier allows an attacker controlling CSS input to cause the host process to read arbitrary local files. This occurs because the PreviousMap feature dereferences sourceMappingURL comments against the local filesystem without proper validation. The flaw can leak file content bytes via JSON.parse error messages and can be used as a file-existence oracle or to cause denial of service. The issue is fixed in version 8.5.12.
