2DescriptionCVE.org
Cap-go before 12.128.2 contains multiple SQL injection vulnerabilities in cloudflare.ts where user-controlled values from API request bodies are interpolated directly into SQL query strings without sanitization or parameterization. Authenticated users with read-level API key permissions can inject arbitrary SQL through deviceIds, search, version_name, cursor, and actions parameters to access analytics data belonging to other users or applications.
AnalysisAI
SQL injection in Capgo (cap-go) before 12.128.2 allows authenticated users with read-level API keys to access analytics data belonging to other tenants by injecting arbitrary SQL through multiple unparameterized parameters in cloudflare.ts. The flaw stems from direct string interpolation of request-body values into Cloudflare Analytics Engine queries, enabling cross-tenant data exposure. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Attacker must hold a valid Capgo API key with at least read-level permissions and reach the analytics endpoints backed by cloudflare.ts (which proxy queries to Cloudflare Analytics Engine); the vulnerable parameters are deviceIds, search, version_name, cursor, and actions in the API request body, and only Capgo deployments running a version before 12.128.2 are affected. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N) with score 7.1 is consistent with the description: network-reachable API, low complexity, low privileges (a read-level API key), no user interaction, and a high confidentiality impact bounded to analytics data with no integrity or availability effect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a Capgo account, obtains a read-level API key, and issues an analytics request whose deviceIds or search field contains a SQL fragment such as a UNION or boolean tautology that breaks out of the intended tenant-scoped WHERE clause. The Cloudflare Analytics Engine then returns analytics rows belonging to other applications or users, which the attacker exfiltrates iteratively across the five injectable parameters. |
| Remediation | Vendor-released patch: upgrade Capgo to 12.128.2 or later, which addresses the SQL injection in cloudflare.ts per GHSA-f83x-p28r-pf74 (https://github.com/Cap-go/capgo/security/advisories/GHSA-f83x-p28r-pf74). … Detailed patch versions, workarounds, and compensating controls in full report. |
