Description¶

ishankportfolio is a portfolio website. Prior to version 1.0.1, contact form submissions could potentially be exposed due to improperly secured client-side database configuration and insufficient access control policies. Applications using publicly exposed database credentials or permissive database rules may allow unauthorised users to read, modify, or abuse stored form submission data. This could impact personally identifiable information (PII) submitted through the website contact form, including names, email addresses, phone numbers, and messages. The issue has been patched in version 1.0.1. Users unable to upgrade immediately can reduce risk by disabling public read/write database access, rotating exposed API keys, restricting database policies to authenticated requests only, moving sensitive operations to secure backend/serverless functions, and/or monitoring database activity logs for suspicious access.
