• CVE-2026-65842: 0.52% estimated exploitation activity in the next 30 days; percentile 44.50 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-65842

Advisory: Plate: SSRF with response disclosure in DOCX image embedding
IDs: CVE-2026-65842, GHSA-4q39-2jhr-7qx8
Record: https://patchnext.com/advisories/cve-2026-65842 (revision 1, source checked 26 Oct 2026, 13:02 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @platejs/docx-io 53.3.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @platejs/docx-io: affected < 53.3.2; fixed in 53.3.2

## Suggested inspection (read-only)
- `npm ls @platejs/docx-io --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @platejs/docx-io.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-4q39-2jhr-7qx8 (GitHub-reviewed advisory GHSA-4q39-2jhr-7qx8 lists affected ranges: npm @platejs/docx-io >=0 <53.3.2)
