Descrição técnica

Botan is a C++ cryptography library. Prior to version 3.11.1, the TLS 1.3 implementation allowed ApplicationData records to be processed prior to the Finished message being received. A server which is attempting to enforce client authentication via certificates can by bypassed by a client which entirely omits Certificate, CertificateVerify, and the Finished message and instead sends application data records. This vulnerability is fixed in 3.11.1.

———A security vulnerability has been detected in chenyme grok2api up to 3.1.6. The impacted element is an unknown function of the file backend/internal/transport/http/inference/voice_ws_handler.go of the component STT Billing. The manipulation leads to enforcement of behavioral workflow. The attack may be initiated remotely. Upgrading to version 3.1.7 is sufficient to resolve this issue. The identifier of the patch is 7ad0f791f0a9eb5a0ddfe38ac4dfcef01e19a6d4. Upgrading the affected component is recommended.11h CVE-2026-1092314.3 MÉD

——9The Germanized for WooCommerce plugin for WordPress is vulnerable to Unauthorized Access of Private Data via Activation Token Reuse in versions up to, and including, 4.1.4. This is due to the `on_user_email_changed` hook — which is responsible for rotating the activation token and recording a pending-email-change marker on an unactivated Customer account — only being registered inside the `is_double_opt_in_login_enabled()` branch when "Disable login for unactivated customers" is set to Yes, leaving the original `?activate=` token valid and entirely unbound to the email address it was issued for when that setting is No. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change their account email to a victim's billing email via the standard `/my-account/edit-account/` form and then redeem their original activation token through `customer_account_activate()`, triggering `link_customer_past_orders()` to reassign any matching guest order to the attacker's account and exposing the original buyer's billing name, street address, phone number, and purchased items on the attacker's My Account order page. Exploitation requires the site to have double opt-in enabled with "Disable login for unactivated customers" explicitly set to No (a non-default configuration), public customer registration enabled, and the original activation token redeemed within its one-day expiry window.4d CVE-2026-1195583.1 BAI
