Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 lacks an UPDATE row-level security policy for the build_requests table, preventing API-key and anonymous access from persisting builder status updates. Attackers can exploit this missing policy to cause build status and error details to remain unpersisted, leaving build_requests rows stuck in pending state with null last_error values.
AnalysisAI
Missing UPDATE row-level security (RLS) policy on Capgo's build_requests table permits low-privileged API-key holders to perform unauthorized status updates against build pipeline records, corrupting build state by leaving rows permanently stuck in a pending state with null last_error values. Capgo versions before 12.128.2 on all platforms are affected. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires possession of a valid Capgo API key or other low-privilege credential that grants authenticated access to the Supabase-backed API. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N) accurately reflects a moderate, low-complexity integrity issue accessible over the network requiring low privileges. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained a valid Capgo API key - through credential theft, key leakage in CI/CD logs, or deliberate low-privilege account creation - sends authenticated UPDATE requests to the build_requests table over the network. By writing malformed or conflicting status values, they leave target build rows stuck in a permanent pending state with null last_error fields, disrupting the CI/CD pipeline visibility and potentially masking real build failures from development teams. … |
| Remediation | Upgrade Capgo to version 12.128.2 or later, which introduces the missing UPDATE RLS policy on the build_requests table. … Detailed patch versions, workarounds, and compensating controls in full report. |
