CVE-2026-71256nanoMODBUS through v1.23.0 contains an out-of-bounds stack read leading to a wild-pointer write in nmbs_read_device_identification_basic() / recv_read_device_identification_res() in nanomodbus.c. A fixed 3-element stack array order[3] = {0,1,2} maps object IDs to buffer indices. The server-supplied object_id field (0-255, read directly from the wire) is used without any bounds check as buf_index = order[object_id]. When a malicious Modbus server sends a Read Device Identification response with object_id >= 3, this reads an out-of-bounds/garbage byte from the stack adjacent to order[], which is then used as an index into a 3-element buffers[] array of char* pointers. The resulting wild pointer is passed to strncpy() as the destination, causing an arbitrary-address write with server-controlled data.

CVE-2026-71254nanoMODBUS through v1.23.0 contains an out-of-bounds write in the Modbus server-side handle_read_file_record() function (FC 0x14, Read File Record) in nanomodbus.c. The function validates that the total request size does not exceed 245 bytes and that each sub-request's record_length is at most 124, but it never validates the CUMULATIVE response size across all sub-requests before processing them. The accumulator response_data_size is declared as uint8_t and is incremented by 2 + record_length*2 for each of up to 35 sub-requests; with 35 sub-requests of record_length=124, the cumulative demand is 8750 bytes, which overflows the uint8_t accumulator. A subsequent loop then calls get_n(), an internal function with no bounds checking, once per sub-request to obtain a pointer into the 260-byte msg.buf receive buffer and advances the internal buf_idx by up to 248 bytes per call; swap_regs() then writes to that pointer unconditionally. A single crafted FC 0x14 request from an unauthenticated network client can cause up to ~8490 bytes to be written out of bounds past the 260-byte buffer, corrupting adjacent memory in the server process and leading to denial of service or potential remote code execution, particularly on embedded/bare-metal targets without memory protection.

CVE-2026-71248Inventory-Management-System-PHP's login.php constructs its authentication query via direct string concatenation of raw POST parameters: $sql = "select * from user where email = '$email' and password = '$password'", with no escaping or parameterization, allowing authentication bypass via a payload such as email=' OR 1=1 LIMIT 1-- -. Separately, delete.php executes mysqli_query($db, "DELETE FROM product WHERE product_id=" . $_GET['id']) with no authentication check and no validation of the id parameter, allowing an unauthenticated attacker to delete arbitrary product rows or perform blind SQL injection via payloads such as id=0 OR SLEEP(5).

CVE-2026-71238DjangoCRM ships with its Django SECRET_KEY hardcoded directly in the committed webcrm/settings.py rather than read from an environment variable. Since this key is used for session signing, CSRF token generation, and password reset tokens, anyone who reads the public repository can forge valid session cookies (including for the superadmin account), forge CSRF tokens, and forge password reset tokens, achieving full account takeover. The repository also ships with DEBUG=True as the default, causing error pages to leak database credentials, email credentials, OAuth data, and internal file paths.

CVE-2026-71237Miantang/IoT-PHP's index.php implements a POST /userlogin route that reads the password directly from $_POST['pwd'] with no sanitization and concatenates it into a raw SQL string: mysql_query("select * from userlists where username='$username' and password='$password' limit 1"). The username value is passed through htmlspecialchars(), which does not encode single quotes by default and therefore does not prevent SQL injection through the password field. An unauthenticated attacker can submit a payload such as pwd=' OR '1'='1 to bypass authentication and, via UNION-based injection, extract arbitrary data from the database.
