Capgo RPC Function Exposes Sensitive Organization Data Publicly

Capgo before 12.128.2 contains an information disclosure vulnerability in the get_orgs_v7(userid) RPC function that remains publicly invokable despite intended private access controls. Unauthenticated attackers can supply arbitrary user UUIDs to retrieve foreign users' organization membership, roles, management emails, and billing metadata.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

Capgo before version 12.128.2 suffers from an authentication bypass vulnerability in its get_orgs_v7(userid) RPC function, allowing unauthenticated attackers to enumerate and retrieve sensitive organizational information for arbitrary users. By simply supplying different user UUIDs, attackers can access organization membership details, user roles, management email addresses, and billing metadata without any credentials or authorization checks. This vulnerability affects all Capgo deployments running vulnerable versions and is particularly dangerous for multi-tenant SaaS environments where organizational data isolation is critical to customer trust and compliance.

Casky's skill-mapped approach to MITRE ATT&CK would identify this attack pattern across two key technique areas: TA0004 (Privilege Escalation) and TA0006 (Credential Access). Using Claude's extended reasoning capabilities, practitioners would see detections for unauthorized API invocations (T1548 - Abuse Elevation Control Mechanism) attempting sequential user UUID enumeration, combined with patterns matching T1589 (Gather Victim Organization Information) as attackers systematically retrieve organizational metadata. The 283 matching skills in Casky's framework would flag suspicious RPC calls lacking proper authentication tokens, unusual parameter patterns with incrementing/sequential UUIDs, and data access anomalies where single requests return organization details across multiple user contexts—all signatures of this public-by-default function exposure.
