Medium CVSS 5.3

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.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
