Detailsinfo

A vulnerability was found in Capgo up to 12.128.1. It has been classified as critical. Affected is some unknown functionality of the file app_versions of the component App Versions Update Enforcement. The manipulation of the argument session_key/key_id with an unknown input leads to a downgrade vulnerability. CWE is classifying the issue as CWE-757. A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Capgo before 12.128.2 contains a policy bypass vulnerability in app_versions update enforcement that allows app-scoped API keys to downgrade encrypted bundles to non-encrypted state. Attackers with app-scoped all API keys can directly update the app_versions table via PostgREST to clear session_key and key_id fields, bypassing organization-enforced encrypted-bundle policies and weakening OTA security controls.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-56217 since 06/19/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1562.010 by the MITRE ATT&CK project.

Upgrading to version 12.128.2 eliminates this vulnerability.
