- 2.1.1· Vendor fix available
- Issue
- When using the CsrfTokenViewHelper the extension discloses the user's session identifier to HTML output without processing of additional cryptographic hashing algorithms. This vulnerability cannot be exploited directly and occurs in combination with a chained attack - like for instance Cross Site Scripting in the frontend output.
Recommended action: Upgrade to 2.1.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
