## What is CVE-2026-2276?

CVE-2026-2276 is a medium-severity cross-site scripting vulnerability in Wix web application, published on 12 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Reflected Cross-Site Scripting (XSS) vulnerability in the Wix web application, where the endpoint ' https://manage.wix.com/account/account-settings ', responsible for uploading SVG images, does not properly sanitize the content. An authenticated attacker could upload an SVG file containing embedded JavaScript code, which is stored and subsequently executed when other users view the image. Exploiting this vulnerability allows arbitrary code to be executed in the context of the victim's browser, which could lead to the disclosure of sensitive information or the abuse of the affected user's session.

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

Affected product: Wix web application. 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.
