CVE-2026-65842: Udecode Plate

High severity, CVSS 8.2. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Udecode Plate: before 53.3.2 (fixed in 53.3.2)
