CVE-2024-5563: reCAPTCHA bypass in authentication flows

CVE-2024-5563 · Severity: medium · CVSS 4.8 · Published 2026-10-21

An authentication protection system fails to apply reCAPTCHA validation to certain login pathways, even when the feature is enabled. This allows attackers to conduct brute-force attacks against user accounts without the intended bot-blocking protection, potentially leading to unauthorized account access and data theft.

Technical details

Due to incomplete implementation, reCAPTCHA validation is not enforced in all authentication flows despite the feature being enabled. This allows attackers to bypass brute-force protections and systematically attempt credential combinations without triggering rate-limiting or bot-detection mechanisms. The vulnerability requires network access and no user interaction.
