Network-reachable multi-tenant service abused by an authenticated org admin (PR:L, AC:L, UI:N); privilege escalation yields high CIA within the tenant with no scope change to other systems.

Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 allows org admins to assign org-scoped RBAC roles at app scope without validating role scope compatibility, including to pending invitees. Attackers can pre-seed malformed high-privilege bindings that survive invite acceptance, enabling accepted low-privilege users to perform unauthorized privileged app actions.
AnalysisAI
Privilege escalation in Capgo before 12.128.2 lets an authenticated org admin assign org-scoped RBAC roles at the narrower app scope without any validation of scope compatibility, and to do so even for pending (not-yet-accepted) invitees. Because these malformed high-privilege bindings persist through invite acceptance, a nominally low-privilege user who accepts the invite gains unauthorized privileged app-level actions. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated account holding org-admin privileges within a Capgo organization (PR:L), and the specific abuse path is assigning an org-scoped RBAC role at app scope - the missing scope-compatibility check is the enabling condition. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score is 8.7 (High) with vector AV:N/AC:L/AT:N/PR:L/UI:N and high confidentiality, integrity, and availability impact to the vulnerable system but no subsequent-system impact (SC:N/SI:N/SA:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A malicious or compromised org admin assigns an org-scoped high-privilege RBAC role at app scope to a pending invitee whose intended role is low-privilege. When that invitee later accepts the invitation, the over-privileged binding persists, and the now-active low-privilege user can perform privileged app actions (e.g., managing app updates or channels) they were never meant to have. … |
| Remediation | Vendor-released patch: upgrade Capgo to 12.128.2 or later, which adds validation of role-scope compatibility during assignment. … Detailed patch versions, workarounds, and compensating controls in full report. |
