Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the wolfSSLX509verifycert function. An attacker can bypass certificate signature validation by supplying a certificate chain where an untrusted intermediate with Basic Constraints set to CA:FALSE is...

CVE-2026-4482 Insight Agent Private Key Information Disclosure via Inherited File Permissions

The installer certificate files in the …/bootstrap/common/ssl folder do not seem to have restricted permissions on Windows systems users have read and execute access. For the client.key file in particular, this could potentially lead to exploits, as this exposes agent identity material to any...

CVE-2026-4482

CVE-2026-4482 involves installer certificate files in the …/bootstrap/common/ssl folder where Windows permissions are not restricted; specifically, client.key is readable/executable by any locally authenticated standard user. The impact is exposure of agent identity material to unprivileged local...

DEBIAN-CVE-2026-5501

wolfSSLX509verifycert in the OpenSSL compatibility layer accepts a certificate chain in which the leaf's signature is not checked, if the attacker supplies an untrusted intermediate with Basic Constraints CA:FALSE that is legitimately signed by a trusted root. An attacker who obtains any leaf...

CVE-2026-5500

wolfSSL's wcPKCS7DecodeAuthEnvelopedData does not properly sanitize the AES-GCM authentication tag length received and has no lower bounds check. A man-in-the-middle can therefore truncate the mac field from 16 bytes to 1 byte, reducing the tag check from 2⁻¹²⁸ to 2⁻⁸...

EUVD-2026-21235

A padding oracle exists in wolfSSL's PKCS7 CBC decryption that could allow an attacker to recover plaintext through repeated decryption queries with modified ciphertext. In previous versions of wolfSSL the interior padding bytes are not validated...

Name of the Vulnerable Software and Affected Versions wolfSSL affected versions not specified Description wolfSSL's wc PKCS7 DecodeAuthEnvelopedData function does not properly sanitize the AES-GCM authentication tag length received and lacks a lower bounds check. This allows a man-in-the-middle...

CVE-2021-47961: Plaintext Storage of a Password

A plaintext storage of a password vulnerability in Synology SSL VPN Client before 1.4.5-0684 allows remote attackers to access or influence the user's PIN code due to insecure storage. This may lead to unauthorized VPN configuration and potential interception of subsequent VPN traffic when combin...
