Potential cross-tenant account takeover vulnerability in Multiple WSO2 Products via Adaptive Authentication and Auto-Login
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
A cross-tenant authentication vulnerability exists in multiple WSO2 products due to improper cryptographic design in Adaptive Authentication. A single cryptographic key is used across all tenants to sign authentication cookies, allowing a privileged user in one tenant to forge authentication cookies for users in other tenants.
