## What is CVE-2026-65842?

CVE-2026-65842 is a high-severity server-side request forgery vulnerability in udecode plate, published on 20 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-918 (Server-Side Request Forgery)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
