Cap-go vulnerabilities

Cap-go before version 12.128.2 contains an authentication logic flaw that allows an attacker to register and control an account bound to a victim's email address before that email is verified. By enabling two-factor authentication on the pre-registered account, the attacker can take control of the account claimed under the victim's identity.

Cap-go before version 12.128.2 contains an authentication bypass vulnerability in OTP verification that allows attackers to bypass email verification by modifying server responses. Attackers can intercept OTP verification requests and manipulate HTTP responses to falsely mark verification successful.

A vulnerability in Cap-go before version 12.128.2 discloses information via the public.transfer_app RPC function, which returns different error messages for existing and non-existing app IDs. Unauthenticated attackers can enumerate valid app IDs by observing error message differences using only the publishable API key.

Cap-go before version 12.128.2 contains an authorization bypass vulnerability in the GET /organization/members endpoint that allows org-limited API keys to bypass limited_to_orgs restrictions. Attackers with such keys can access membership data from organizations outside their assigned scope.

Cap-go before version 12.128.2 contains a privilege inversion vulnerability in GET /build/logs/:jobId that allows read-only API key holders to cancel running native builds. The endpoint registers an abort listener on the SSE stream that unconditionally invokes cancelBuildOnDisconnect() using the privileged server-side BUILDER_API_KEY.

Cap-go before version 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.

Cap-go before version 12.128.2 contains an information disclosure vulnerability in the OPTIONS /build/upload/:jobId/* endpoint. This allows unauthenticated attackers to enumerate valid builder job IDs through observable response discrepancies.

Cap-go before version 12.128.12 contains a broken cursor pagination vulnerability in the /private/devices endpoint, allowing authenticated attackers to cause duplicate-page loops and make later rows unreachable.

Cap-go prior to 12.128.2 contains an account takeover vulnerability in its email change mechanism that allows an attacker with temporary authenticated session access to change the registered email address without re-authentication. Attackers can redirect verification to an attacker-controlled email address and subsequently perform a password reset to permanently take over the victim's account.
