SQL injection in Kong Gateway (Enterprise and Open Source) Hybrid Mode clustering logic allows an attacker who can reach the Control Plane's clustering port and present a valid mTLS client certificate and key to inject arbitrary SQL into the Control Plane's backing database, resulting in unauthorized read and write access to gateway configuration and related data. Successful exploitation yields high confidentiality, integrity, and availability impact on the Control Plane database (CVSS 4.0 base 7.5 / assessed CVSS 3.1 8.8), but the prerequisites are substantial: the deployment must be running the Control Plane/Data Plane split, the attacker must have adjacent network access to the normally internal clustering channel, and must hold legitimate clustering credentials, which effectively limits realistic abuse to compromised Data Plane nodes or insiders with stolen cluster keys. No public exploit code or confirmed active exploitation (CISA KEV) has been identified at time of analysis.
Signature-verification bypass in Kong API Gateway Enterprise lets an unauthenticated remote attacker present a forged JWT that the gateway accepts as valid, defeating token-based authentication for the MCP OAuth2 and DataKit integration code paths. The vulnerable logic fails to confirm that the JWT's declared signing algorithm is compatible with the key type actually used for verification, so an attacker who can reach a protected endpoint that relies on these integrations can slip through as an authenticated principal; the independent assessment scopes the impact to the backend resources the gateway protects (C:H/I:H under a changed-scope CVSS:3.1 vector) rather than to the gateway host itself. Exposure is gated by configuration - gateways that do not enable MCP OAuth2 or DataKit JWT validation are not reachable - and no public exploit code or confirmed active exploitation was identified at time of analysis.
SAML authentication bypass in Kong Enterprise Gateway allows an unauthenticated remote attacker to impersonate arbitrary users, including administrators, by submitting a crafted SAML response containing an unsigned assertion. Exploitation is strictly gated by a non-default configuration: the Kong SAML plugin's validate_assertion_signature option must have been explicitly set to false, since it defaults to true - default deployments are not affected. No public exploit code has been identified at time of analysis and the flaw is not listed in CISA KEV; patch status is Vendor-released patch: Kong Gateway 3.15.0.3.
A vulnerability was found in Konga 2.8.3 on Kong. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
The official kong docker images before 1.0.2-alpine (Alpine specific) contain a blank password for a root user. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Cross-site scripting (XSS) vulnerability in the phptemplate_preprocess_node function in template.php in the Inf08 theme 6.x-1.x before 6.x-1.10 for Drupal allows remote authenticated users with the. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. No vendor patch available.
