Summary
An issue was discovered in Bosch Sensortec COINES_SDK versions 2.0 through 2.11. The host streaming API function coines_read_stream_sensor_data() fails to validate the boundaries of the caller-provided destination buffer. Internally, comm_intf_process_stream_response() discards the requested number_of_samples argument and copies the entirety of the streaming ring buffer's accumulated data into coines_stream_rsp_buf. Subsequently, coines_read_stream_sensor_data() unconditionally executes a memcpy of the ring buffer size into the caller-provided buffer without verifying if the destination memory allocation is large enough. A malicious or compromised hardware board connected via USB or BLE can exploit this by streaming a high volume of sensor samples, causing a heap or stack-based buffer overflow on the host desktop environment. This can result in a Denial of Service (DoS) or potential arbitrary code execution on the host machine.
Risk Assessment
A malicious or compromised device connected via USB or BLE can trigger a buffer overflow on the host machine, causing a denial of service or potential arbitrary code execution. This poses a serious threat to workstations used for sensor development and testing.
Recommendation
Update COINES_SDK to a version later than 2.11 if available, or avoid connecting untrusted hardware boards via USB/BLE to workstations. Consider limiting the privileges of the host process handling the data stream.

A security flaw has been discovered in TOTOLINK CA300-PoE 6.2c.884. This impacts the function setWiFiMultipleConfig of the file /cgi-bin/cstecgi.cgi. Manipulation of the argument Key1Str1 results in a buffer overflow. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks.
- CVE-2026-123966Critical
A vulnerability was found in Tenda AC19 version 16.03.10.07 in the saveParentControlInfo function of the /goform/saveParentControlInfo file. Manipulating the deviceId argument causes a heap-based buffer overflow. The attack can be carried out remotely, and the exploit has been publicly disclosed.
- CVE-2026-120984Critical
A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during setup. An authenticated attacker with client management permissions can bypass security controls and upload a malicious JavaScript policy that executes on the server.
- CVE-2026-122041Critical
The Checkout Field Editor for WooCommerce (Pro) plugin for WordPress up to and including 3.8.0 is vulnerable to unauthorized deletion of arbitrary attachments due to a missing capability/ownership check in the ajax_remove_uploaded() function. The handler is registered for both wp_ajax and wp_ajax_nopriv and gated solely by the 'file_handling_nonce' nonce, which is exposed in the public checkout page markup.
- CVE-2026-119075Critical
The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in FormHandler::validate_checkout_fields() in versions up to and including 1.1.4. The checkout registration path stores the raw $_POST['user_roles'] value without validation, and add_user_data() injects it as the new account's role.
- CVE-2026-118066Critical
The LatePoint plugin for WordPress is vulnerable to authentication bypass via account takeover in versions up to and including 5.7.6. OsModel::build_conditions_query() compares WHERE-clause values against literal strings 'IS NULL' and 'IS NOT NULL' and concatenates a match directly into SQL without binding, allowing unauthenticated attackers to send params[password_reset_token]=IS NOT NULL to the public customer_cabinet__change_password AJAX route and overwrite the lowest-id customer's password.
- CVE-2026-104014Critical
The Naimur Email OTP Verification for WooCommerce plugin is vulnerable to authentication bypass in versions up to and including 2.1.0. The password-reset finalization endpoint authorizes the reset solely by the presence of a database row marking an email as 'VERIFIED', with no timestamp check, session binding, or per-reset token, and the scheduled cleanup cron has no handler so it never runs.
- CVE-2026-123961Critical
A vulnerability was detected in TOTOLINK CA300-PoE version 6.2c.884 affecting the setWiFiBasicConfig function in /cgi-bin/cstecgi.cgi. Manipulation of the KeyStr argument leads to a buffer overflow. The attack can be initiated remotely and a public exploit is available.
