Details

As written in the advisory (Markdown source, shown as plain text).

## Summary `@platejs/docx-io` can fetch remote image URLs while converting HTML to DOCX. When an application converts attacker-controlled HTML in a server-side or privileged environment, this can cause the application environment to make unintended outbound requests and include fetched image data in the generated DOCX. ## Impact Applications are affected when they use `@platejs/docx-io` to convert untrusted HTML that may contain remote image references, especially in server-side conversion workflows or environments with access to internal network resources. Affected package: - `@platejs/docx-io` versions `< 53.3.2` ## Patched versions Upgrade to `@platejs/docx-io` version `53.3.2` or later. ## Workarounds If you cannot upgrade immediately, do not pass untrusted HTML with remote image URLs to DOCX export. Sanitize untrusted HTML to remove remote image references, convert trusted images to data URIs before conversion, or run conversion in an environment with restricted outbound network access. ## Credits Thanks to EQSTLab for reporting this issue.
