Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) Affecting org.apache.druid.extensions:druid-kerberos package, versions [,35.0.0)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2025-59390 (opens in a new tab)How to fix?
Upgrade org.apache.druid.extensions:druid-kerberos to version 35.0.0 or higher.
Overview
Affected versions of this package are vulnerable to Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) due to a weak fallback secret when the druid.auth.authenticator.kerberos.cookieSignatureSecret configuration is not explicitly set. An attacker can predict or brute force the secret used to sign authentication cookies by exploiting the use of a non-cryptographically secure random number generator, potentially enabling token forgery or bypassing authentication.
