Description
schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the URL path concatenation and encoding module. The application splices untrusted extension path and attacker-controlled query string into a path buffer, then invokes urlencode without validating the final string length. Remote attackers can construct an oversized malicious URL path and query string to trigger out-of-bounds heap write, resulting in arbitrary code execution, information disclosure, service crash, or privilege escalation.
