This flaw allows an authenticated attacker to manipulate user account settings by changing the primary email address without requiring the current password for re-authentication or verification of the existing email. The vulnerability's CVSS v3.1 base score is 7.3 (High) and v4.0 is 8.4 (High), indicating significant risk. Exploitation enables attackers to hijack account recovery processes and bypass multi-factor authentication (MFA) protections, leading to full account compromise. This represents a severe threat to the confidentiality and integrity of user accounts within Capgo applications, as it provides a direct path to account takeover for any attacker who can gain initial authenticated access.

Attack Chain

1. An attacker gains access to a valid session cookie or an already authenticated browser session belonging to a target Capgo user.
2. The attacker uses this authenticated session to navigate to the email change functionality within the Capgo application.
3. The attacker submits a request to modify the account's registered email address to one under their control.
4. Due to CVE-2026-56308, the Capgo application processes this request without requiring the user to re-authenticate with their current password or verify the existing email address.
5. The target Capgo user's email address is successfully updated to the attacker-controlled email.
6. The attacker then initiates a password reset or account recovery process for the compromised Capgo account.
7. The password reset link or code is sent to the newly configured attacker-controlled email address.
8. The attacker uses the received reset information to set a new password, effectively taking full control of the victim's Capgo account and bypassing any multi-factor authentication mechanisms.

Impact

Successful exploitation of CVE-2026-56308 leads directly to full account takeover for affected Capgo users. This enables attackers to gain unauthorized access to all data and functionalities associated with the compromised account. Victims may experience loss of access to their Capgo applications, potential exposure of personal or sensitive information, and further unauthorized actions performed by the attacker using the hijacked account, including impersonation or access to connected third-party services. The bypass of multi-factor authentication renders a critical security layer ineffective, severely degrading overall account security.

Recommendation

• Immediately patch CVE-2026-56308 by upgrading Capgo to version 12.128.2 or later to mitigate the vulnerability.
• Review and strengthen authentication mechanisms for sensitive actions, ensuring re-authentication with the current password or multi-factor authentication is required for critical changes like email address updates.

This flaw allows a previously appointed super_admin user, even after being demoted from that role, to retain unauthorized access to specific Remote Procedure Calls (RPCs): delete_non_compliant_bundles and count_non_compliant_bundles. The root cause is an issue where the org_users.user_right column is not properly cleared when role bindings are removed. An attacker can exploit this oversight to continue performing high-privilege actions, such as enumerating and bulk deleting non-compliant bundles across an entire organization, effectively maintaining super_admin capabilities indefinitely despite their demoted status. This vulnerability poses a significant risk to data integrity and service availability for organizations utilizing Capgo.

Attack Chain

1. An adversary, previously a super_admin user within a Capgo organization, is officially demoted from their administrative role.
2. Due to the vulnerability (CVE-2026-56241), the org_users.user_right column associated with the demoted user's account is not properly cleared.
3. The demoted user exploits this oversight by continuing to invoke the delete_non_compliant_bundles and count_non_compliant_bundles RPCs.
4. The Capgo application, processing these RPCs, grants access based on the stale super_admin privileges.
5. The adversary successfully enumerates all non-compliant bundles within the organization.
6. The adversary proceeds to bulk delete these non-compliant bundles across the entire organization.
7. The objective is achieved, leading to unauthorized data manipulation and potential service disruption.

Impact

Successful exploitation of CVE-2026-56241 grants a demoted super_admin user the ability to perform indefinite and unauthorized enumeration and bulk deletion of non-compliant bundles across the entire Capgo organization. This can lead to severe data integrity issues, potential data loss, and significant service disruption by removing essential data assets. The CVSS v3.1 Base Score of 8.3 indicates a high severity risk, reflecting the critical impact on confidentiality, integrity, and availability. Organizations using affected Capgo versions face a substantial risk of malicious or accidental deletion of critical data by privileged insiders who should no longer possess such capabilities.

Recommendation

• Patch CVE-2026-56241 immediately by upgrading Capgo to version 12.128.2 or later to ensure org_users.user_right columns are properly cleared upon role demotion.
• Review Capgo application logs for unexpected delete_non_compliant_bundles or count_non_compliant_bundles RPC calls originating from demoted user accounts.
• Implement robust auditing and alerting for critical administrative actions within Capgo, paying particular attention to bundle management operations by all users, especially recently demoted ones.
