Network-reachable API with a read-level key (PR:L), no UI, straightforward injection (AC:L); impact limited to cross-tenant analytics disclosure, so C:H and I:N/A:N.

Lifecycle Timeline
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. No public exploit identified at time of analysis, though a VulnCheck advisory and an upstream GitHub Security Advisory document the issue.
Technical ContextAI
Capgo is an open-source live-update and OTA delivery platform for Capacitor mobile apps, with a backend that proxies analytics queries through Cloudflare Workers. The vulnerable cloudflare.ts module constructs SQL strings sent to Cloudflare Analytics Engine by concatenating user-supplied fields (deviceIds, search, version_name, cursor, actions) directly into the query, the textbook CWE-89 anti-pattern. Because the Analytics Engine SQL dialect does not enforce row-level tenant isolation by itself - the application relies on WHERE clauses to scope per-user data - injecting additional SQL syntax lets an attacker rewrite or extend those predicates and read other tenants' rows. CPE cpe:2.3:a:cap-go:capgo:*:*:*:*:*:*:*:* covers all Capgo versions prior to the fix.
RemediationAI
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). Until the upgrade is deployed, operators should rotate or revoke read-level API keys held by untrusted tenants to shrink the population of accounts able to reach the vulnerable endpoints, and place a WAF or reverse-proxy rule in front of the analytics API to reject request bodies in which deviceIds, search, version_name, cursor, or actions contain SQL meta-characters such as quotes, semicolons, or comment sequences - accepting that this will break legitimate searches containing those characters. Multi-tenant SaaS operators should additionally audit Cloudflare Analytics Engine query logs for anomalous WHERE-clause patterns indicating prior cross-tenant access, and reference the VulnCheck write-up at https://www.vulncheck.com/advisories/cap-go-sql-injection-in-cloudflare-analytics-engine-queries-via-cloudflare-ts for indicators.
