Inyección SQL crítica en SiYuan v3.7.2 y anteriores permite ejecución de comandos

SiYuan versiones 3.7.2 y anteriores contienen una vulnerabilidad de inyección SQL en la función de búsqueda de referencias inversas y menciones. El fallo radica en la concatenación insegura de metadatos de bloques (título, nombre, alias, texto de anclaje) con palabras clave del cliente en consultas SQL, escapando solo comillas dobles pero no simples. Un atacante puede inyectar comillas simples para ejecutar comandos SQL arbitrarios, comprometiendo la integridad y confidencialidad de bases de datos locales en sistemas Windows, macOS y Linux.

The LINUXTCP port of FreeModbus contains an off-by-one bounds check in xMBPortTCPPool() (demo/LINUXTCP/port/porttcp.c). The check `if (usTCPFrameBytesLeft > MB_TCP_BUF_SIZE)` uses a strict greater-than comparison instead of greater-than-or-equal against the 263-byte MB_TCP_BUF_SIZE limit. An MBAP frame with a Length field of 264 makes usTCPFrameBytesLeft equal to 263, which passes the flawed check…

Run ADS I/O with the credentials captured when the SMB handle was opened.
