CWE
- CWE-89 - Improper neutralization of special elements used in an SQL command ('SQL injection')
Summary
A SQL Injection (SQLi) affects the Kong Gateway (Enterprise and Open Source) clustering communication logic when operating in Hybrid Mode. The issue can be triggered by sending specially crafted RPC requests to the Control Plane (CP), leading to potential unauthorized database access. Leveraging the issue requires network access to the Control Plane’s clustering port and a valid client certificate and key.

- CWE-241 - Improper handling of unexpected data type
Summary
A JWT signature verification vulnerability affects Kong components that perform JWT validation for MCP OAuth2 or DataKit integrations inside Kong API Gateway Enterprise. The affected code does not properly validate that the JWT signing algorithm is compatible with the type of key used for verification.
As a result, an unauthenticated remote attacker may be able to craft a forged JWT that is incorrectly accepted as valid, leading to authentication bypass and potential compromise of confidentiality, integrity, and availability.

- CWE-288 - Authentication bypass using an alternate path or channel
Summary
A SAML authentication bypass vulnerability affects the Kong SAML plugin when the validate_assertion_signature option is explicitly set to false. This option is enabled by default. When disabled, the plugin may extract the SAML identity from an unsigned assertion and authenticate the user without verifying a valid cryptographic signature.
As a result, an unauthenticated remote attacker may be able to submit a crafted SAML response and impersonate arbitrary users, including administrators

CWE
- CWE-323 - Reusing a Nonce, Key Pair in Encryption
Summary
Kong Event Gateway versions 1.0.0 through 1.1.1 and 1.2.0 do not enforce key rotation before reaching NIST SP 800-38D recommended usage limit for AES-GCM encryption keys with random nonces when the AWS IAM encryption feature is enabled.
If a producer sends messages at a sustained high rate without key rotation, which only occurs on reboot of the Kong Event Gateway instance, the probability of a nonce collision becomes non-negligible. An authorized consumer who detects a nonce collision can recover parts of plaintext from the affected messages.
New versions 1.1.2 and 1.2.1 enforce automatic key rotation before the recommended usage limit is reached.

CWE
- CWE-426 - Untrusted Search Path
Summary
A vulnerability was found in Kong Insomnia up to 10.3.0 and classified as critical. This issue affects some unknown processing in the library profapi.dll. The manipulation leads to untrusted search path. An attack has to be approached locally. The complexity of an attack is rather high. The exploitation is known to be difficult. The real existence of this vulnerability is still doubted at the moment. The vendor is not able to reproduce the issue.
