CVE-2026-61500

CVE-2026-61500: Rejetto HFS session forgery to RCE CVE-2026-61500 is an unauthenticated session-forgery vulnerability in Rejetto HFS 3.0.0 through 3.2.0. HFS generated its Koa session-cookie signing key with JavaScript Math.random and exposed outputs from the same V8 PRNG in the unauthenticated S...

ReplicatedRandom

Node MWC1616 See README in node folder Java LCG Given a double generated from nextDouble of a java.util.Random, recreate a Random with the same state. This ReplicatedRandom can then be used to predict the future values of the original Random. Example: Random r = new Random; ReplicatedRandom rr =...

VulnCheck KEV: CVE-2026-61500

Rejetto HFS 3.0.0 through 3.2.0 derives its session-cookie signing key from the non-cryptographic Math.random generator and discloses outputs of the same generator to unauthenticated clients during login. A remote attacker can collect a small number of login responses, reconstruct the generator's...
