Private Key Extraction

tiny-secp256k1 is vulnerable to private key extraction. The vulnerability is due to the ability to bypass Buffer.isBuffer checks when the global Buffer is overridden by the NPM buffer package, which allows an attacker to reuse the nonce k across different messages and extract the private key by...

GHSA-H34R-JXQM-QGPR juju/utils leaks private key in certs

Summary Certs generated by v4 contain their private key. Details Background Recently, I encountered an API in Go that’s easy to misuse: sha512.Sum384 and sha512.New384.Sum look very similar and behave very differently. https://go.dev/play/p/kDCqqoYk84k demonstrates this. I want to discuss extendi...

Name of the Vulnerable Software and Affected Versions: tiny-secp256k1 versions prior to 1.1.7 Description: A private key can be extracted when signing a malicious JSON-stringifiable object, affecting environments where the global Buffer is the buffer package. The Buffer.isBuffer check can be...

The vulnerability of Hikvision’s IP cameras’ microprogramming software lies in the fact that the operation value escapes the buffer in memory when processing the PrivateKey parameter. This allows a intruder to trigger a service failure.

The vulnerability of Hikvision’s IP cameras’ microprogramming software is related to the issue where the operation data escapes from the buffer into memory when processing the PrivateKey parameter. Exploiting this vulnerability can allow a remote attacker to cause a service failure by sending a...

Overview Affected versions of this package are vulnerable to Use After Free in the privatekeyfromfile function. An attacker can potentially access sensitive information or modify data, under certain circumstances such as the specified filename not existing. Note: The vulnerable function has been...

CVE-2025-52464

Meshtastic is an open source mesh networking solution. In versions from 2.5.0 to before 2.6.11, the flashing procedure of several hardware vendors was resulting in duplicated public/private keys. Additionally, the Meshtastic was failing to properly initialize the internal randomness pool on some...

CVE-2025-52464

Meshtastic versions 2.5.0–2.6.10 expose a vulnerability where flashing procedures can duplicate public/private keys and the RNG may have low entropy, allowing an attacker to decrypt Direct Messages after collecting compromised keys. This is caused by key generation timing and insufficient randomn...
