Capgo (Cap-go/capgo) before 12.128.2 contains an information disclosure vulnerability in the Supabase PostgREST SECURITY DEFINER RPC function public.rescind_invitation that allows unauthenticated attackers to enumerate organization existence. The function returns distinct error messages (NO_ORG vs NO_RIGHTS) when called with only a publishable API key, enabling attackers to discover valid organization IDs and increase the attack surface for targeted phishing or social engineering campaigns.

——5Cap-go before 12.128.2 contains an information disclosure vulnerability in the public.transfer_app RPC function that returns distinct error messages for existing versus non-existing app IDs. Unauthenticated attackers can enumerate valid app IDs by observing error message differences when calling transfer_app with only the publishable API key.8dCVE-2026-58503—27.8%
——8Frappe is a full-stack web application framework. Prior to 16.16.0 and 15.106.0, user enumeration could be performed via the reset_password endpoint. This issue is fixed in versions 16.16.0 and 15.106.0.8dCVE-2026-519267.5 HIG28.3%
——8An issue in docuForm GmbH FSM Client v.11.11c allows a remote attacker to obtain sensitive information via the login.php component. A vulnerability was identified in the authentication mechanism that allows user enumeration through the login interface. An attacker can differentiate between valid and invalid usernames based on variations in server responses. This information can be leveraged to identify existing accounts and facilitate further attacks, including brute-force or credential stuffing.11dCVE-2026-443325.3 MED40.6%
——12Fiber is an Express inspired web framework written in Go. Prior to 3.3.0, the default Authorizer function in the BasicAuth middleware in middleware/basicauth/config.go uses short-circuit evaluation that skips password hash comparison for non-existent usernames, enabling reliable remote username enumeration through response timing differences. This issue is fixed in version 3.3.0.6dCVE-2026-563275.3 MED17.7%
——5Capgo before 12.128.2 contains an information disclosure vulnerability in the public.invite_user_to_org RPC function that allows unauthenticated attackers to enumerate organization existence by observing distinct error responses. Attackers can call the SECURITY DEFINER function with a publishable API key to determine if an organization ID exists based on NO_ORG versus NO_RIGHTS responses, enabling tenant enumeration attacks.20dCVE-2026-141125.3 MED12.3%
——4Inappropriate implementation in Enterprise in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Low)20d
