CVE-2026-51266

schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the HTTP request header construction logic. The application dynamically splices attacker-controlled host name, path, query string, and multiple HTTP header fields into a fixed psptr heap buffer without proper size...

CVE-2026-51269

schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the connecttospeech function. The application accepts attacker-controlled long speech text input, performs URL encoding, and directly appends the encoded result into a fixed psptr heap buffer when constructing HTT...

CVE-2026-51267

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...

EUVD-2026-49859

schreibfaul1 ESP32-audioI2S v3.4.5 has an integer underflow vulnerability in the MP3Decoder::GetBits function of the MP3 decoder due to unchecked bit reading operations. The lack of validation on the nBits parameter causes the cachedBits counter to underflow to negative values, leading to invalid...

EUVD-2026-49927

In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 SYLT synchronized lyrics parser in audiolib allows remote attackers to cause a denial of service application crash, information disclosure, or potential arbitrary code execution via a crafted MP3 file. The vulnerabili...

CVE-2026-51260

Unsafe fixed-size memcpy operation in AudioBuffer::writeSpace of schreibfaul1 ESP32-audioI2S 3.4.5 allows remote heap buffer overflow. The code copies a full UINT16MAX bytes without validating destination available space, causing out-of-bounds memory write...

CVE-2026-51271

In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the WAV header parsing function readWAVHeader. The function reads untrusted chunk size and bytes-to-skip value directly from malicious WAV files without reasonable range restriction. Abnormally large bts an...

CVE-2026-51251

Schreibfaul1 ESP32-audioI2S 3.4.5 has a buffer overflow vulnerability in the MP3Decoder::decode function of the MP3 decoder due to missing size validation on untrusted mainDataBegin and nSlots values...

CVE-2026-51254

schreibfaul1 ESP32-audioI2S v3.4.5 has an integer underflow vulnerability in the MP3Decoder::GetBits function of the MP3 decoder due to unchecked bit reading operations. The lack of validation on the nBits parameter causes the cachedBits counter to underflow to negative values, leading to invalid...

CVE-2026-51268

ESP32-audioI2S 3.4.5 is affected by a heap-based buffer overflow in the host parsing logic. The dismantle_host() function parses untrusted host and URL input, and subsequent code uses clone_from() to copy parsed host, request host, extension, and query_string segments into fixed heap buffers with...

EUVD-2026-49868

schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the htmlToUTF8 HTML entity decoding function. The function parses attacker-controlled malicious HTML entities and uses memmove and memcpy to rearrange string content without validating buffer remaining size and...

CVE-2026-51244

The CVE affects schreibfaul1 ESP32-audioI2S 3.4.5, where a buffer overflow originates from UnpackFrameHeader() due to multiple attacker-controlled index parameters used to access static and heap table arrays without range checking. Invalid index values permit out-of-bounds memory writes and heap ...

EUVD-2026-49420

schreibfaul1 ESP32-audioI2S 3.4.5 has a buffer overflow vulnerability in UnpackFrameHeader. Multiple attacker-controlled index parameters are used to access static and heap table arrays without range limitation. Invalid index values lead to out-of-bounds memory writing and heap buffer overflow...
