HighCVSS 7.5 EPSS 0.46%
Ratpack is a toolkit for creating web applications. In versions prior to 1.9.0, the default configuration of client side sessions results in unencrypted, but signed, data being set as cookie values. This means that if something sensitive goes into the session, it could be read by...

HighCVSS 7.5 EPSS 2.2%
An issue was discovered in Ratpack before 1.7.5. Due to a misuse of the Netty library class DefaultHttpHeaders, there is no validation that headers lack HTTP control characters. Thus, if untrusted data is used to construct HTTP headers with Ratpack, HTTP Response Splitting can oc...

CVE-2019-11808 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Ratpack
PublishedLowCVSS 3.7 EPSS 1.3%Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequen...
