Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains an unsecured images bucket lacking any row level security controls, allowing unauthenticated attackers to read, insert, and delete stored app icons. Remote attackers can exploit this misconfiguration to delete all icons and leak sensitive app IDs and user IDs.
AnalysisAI
Unauthenticated remote attackers can read, insert, and delete stored app icons in Capgo (all versions before 12.128.2) due to a Supabase images bucket entirely lacking row-level security (RLS) controls. Exploitation leaks sensitive app IDs and user IDs embedded in bucket metadata, and enables full icon deletion causing visual degradation of hosted applications. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions are required - the CVSS 4.0 vector (PR:N, AC:L, AT:N) confirms zero privileges, low complexity, and no special attack requirements. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N) confirms unauthenticated, network-accessible, low-complexity exploitation - a very low barrier to exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends HTTP GET requests directly to the Capgo deployment's Supabase storage API endpoint for the images bucket, receiving a full listing of stored app icons along with object metadata containing app IDs and user IDs - no credentials or tokens required. The attacker then issues HTTP DELETE requests to systematically remove all icons, causing visual degradation for end users of Capgo-managed applications. … |
| Remediation | Upgrade Capgo to version 12.128.2 or later, which is confirmed by the vendor advisory at https://github.com/Cap-go/capgo/security/advisories/GHSA-8hq3-gg3m-vwvr to introduce proper RLS controls on the images bucket. … Detailed patch versions, workarounds, and compensating controls in full report. |
