CVE-2023-22893
Published: April 11, 2026
Official Description
Strapi through 4.5.5 does not verify the access or ID tokens issued during the OAuth flow when the AWS Cognito login provider is used for authentication. A remote attacker could forge an ID token that is signed using the 'None' type algorithm to bypass authentication and impersonate any user that use AWS Cognito for authentication.
Risk Analysis
Strapi through 4.5.5 fails to verify access or ID tokens during the OAuth flow when using AWS Cognito, allowing remote attackers to forge 'None' type ID tokens. This bypasses authentication, enabling impersonation of any user utilizing AWS Cognito. The vulnerability is actively exploited, posing a significant risk to user accounts.
This vulnerability is actively being exploited in the wild. A remote attacker can forge ID tokens to bypass authentication.
Upgrade Strapi to a version beyond 4.5.5 that includes a fix for the AWS Cognito OAuth token verification issue. Ensure proper token validation mechanisms are in place.
Technical Analysis
CVE-2023-22893 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-22893 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
