CVE-2026-42952 affects Hydro-Québec's Le Circuit Electrique charging station backend. The vulnerability is caused by the absence of throttling on repeated authentication attempts, allowing an unauthenticated remote attacker to send excessive authentication requests without rate limiting or lockout controls. This weakness can be abused to overwhelm backend authentication handling and trigger a denial-of-service condition. Reported affected versions are version 0 through versions earlier than June 2026 under the vendor's custom versioning scheme.
