CVE-2026-65842 udecode CVE debrief

Who should care

Defenders responsible for the Plate rich-text editor deployment, particularly those managing server-side environments, should assess exposure and apply the patch. They should also review internal network resources for potential exposure and monitor for potential server-side request forgery attacks.

Why it matters

CVE-2026-65842 allows server-side request forgery with response disclosure in the Plate rich-text editor, impacting defenders managing server-side environments.

• Server-side request forgery with response disclosure.
• Potential resource consumption from attacker-selected remote responses.
• Verification of internal network resource exposure.
• Patch application priority to prevent exploitation.

Technical summary

The @platejs/docx-io library fetches remote image URLs while converting attacker-controlled HTML, allowing server-side request forgery with response disclosure. This issue allows attackers to make requests to internal network resources and include the fetched image bytes in the generated DOCX, potentially leading to server-side request forgery with response disclosure and resource consumption from attacker-selected remote responses. The vulnerability is fixed in version 53.3.2 of the Plate rich-text editor. Applications can also incur resource consumption from attacker-selected remote responses.

Defensive priority

Defenders should prioritize verifying exposure and applying the patch, as the vulnerability allows server-side request forgery with response disclosure.

Recommended defensive actions

• Verify if the application is using a vulnerable version of the Plate rich-text editor.
• Apply the patch to upgrade to version 53.3.2 or later.
• Monitor for potential server-side request forgery attacks.
• Review internal network resources for potential exposure.
• Track exceptions and retest remediated assets.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
