## What is CVE-2026-105694?

CVE-2026-105694 is a medium-severity cross-site scripting vulnerability in penpot, published on 5 Oct 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, authenticated users with file-edit permission can upload SVG media whose scripts, event-handler attributes, and foreignObject elements are stored without sanitization and served as image/svg+xml from the Penpot origin. A victim who navigates to the asset URL executes attacker-controlled JavaScript in that origin, allowing requests and data access with the victim's Penpot session authority. This issue is fixed in version 2.18.0.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Affected product: penpot. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
5. If nothing in the project is affected, say so and change nothing.
