Fluentd is Vulnerable to Remote Code Execution (RCE) via Arbitrary File Write in `${tag}` Placeholder

Fluentd allows dynamically constructing file paths using the $tag placeholder. It was discovered that validation for this placeholder was insufficient. If a Fluentd instance is configured to receive logs from untrusted sources and uses the $tag placeholder in file configurations such as the path...

CVE-2026-6331

CVE-2026-6331 describes an HMAC zero-length tag forgery in EVP_DigestVerifyFinal. The OpenSSL-compatibility HMAC verify path allowed a zero-length or truncated tag to pass because the signature length check only ensured it did not exceed the MAC length. The fixed behavior now requires the supplie...
