CVE-2026-65842 (GCVE-0-2026-65842)

Vulnerability from cvelistv5 – Published: 2026-08-20 16:40 – Updated: 2026-08-21 16:23

Title

Plate: SSRF with response disclosure in DOCX image embedding

Summary

Plate is a rich-text editor with AI and shadcn/ui. Prior to 53.3.2, @platejs/docx-io fetches remote image URLs while converting attacker-controlled HTML through htmlToDocxBlob in a server-side or privileged environment. The converter can make requests to internal network resources and include the fetched image bytes in the generated DOCX, allowing server-side request forgery with response disclosure. Applications can also incur resource consumption from attacker-selected remote responses. This issue is fixed in version 53.3.2.

Severity

GHSA-4Q39-2JHR-7QX8

Vulnerability from github – Published: 2026-09-02 22:14 – Updated: 2026-09-02 22:14

Summary

Plate: SSRF with response disclosure in DOCX image embedding

Details

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
