Executive Summary

CVE-2026-53982 is a denial-of-service vulnerability in Capgo Console versions prior to 12.28.2 that occurs during the account deletion process.

When an attacker triggers account deletion while a device identifier is linked to an active session, the platform incorrectly associates the deletion state with that device identifier.

This causes the affected device or browser environment to be redirected to an account-disabled page for about 30 days, blocking any login or registration attempts from that device.

Impact Analysis

This vulnerability can cause a denial-of-service condition by preventing legitimate users from authenticating or onboarding using the affected device or browser.

Users of the affected device will be redirected to an account-disabled page for approximately 30 days, effectively blocking access to their accounts or the ability to register new accounts from that device.

This leads to poor recovery experiences and potential disruption of normal platform usage.

Detection Guidance

This vulnerability can be detected by monitoring for devices or browser environments that are redirected to the /accountDisabled page and are unable to log in or register for approximately 30 days after an account deletion event.

Audit checks, monitoring, and logging of account deletion events and device identifier associations are recommended to detect abnormal or abusive behavior related to this vulnerability.

Specific commands are not provided in the available resources, but network or application logs should be examined for repeated redirects to the account-disabled page and failed authentication attempts from the same device identifier following account deletions.

Mitigation Strategies

Immediate mitigation steps include updating Capgo Console to version 12.28.2 or later, where this vulnerability has been addressed.

Additional recommended measures are to decouple device identity from account deletion, maintain device neutrality after account removal, invalidate only session tokens, regenerate device identifiers on new authentication, and implement clear device ban logic with recovery mechanisms.

Implementing audit checks, monitoring, and logging can also help prevent abuse and detect exploitation attempts.
