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 =...

CVE-2025-71461

Zipline before 4.0.2 contains a predictable filename vulnerability that allows attackers to infer other users' upload filenames by recovering the Math.random generator state. Attackers with five consecutive gfycat-style filenames can reconstruct the random state to predict previous and future...

Zipline before 4.0.2 contains a predictable filename vulnerability that allows attackers to infer other users' upload filenames by recovering the Math.random generator state. Attackers with five consecutive gfycat-style filenames can reconstruct the random state to predict previous and future...

CVE-2025-71461

The Zipline application, versions before 4.0.2 , is vulnerable to a predictable filename flaw caused by the use of a cryptographically weak pseudo-random number generator (Math.random ). By obtaining five consecutive gfycat-style filenames, an attacker can reconstruct the random generator's state...

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...

Attackers Target Rejetto HFS Flaw That Enables Admin Session Forgery and RCE

A critical security flaw impacting Rejetto HTTP File Server HFS is witnessing active exploitation attempts, according to VulnCheck. The vulnerability in question is CVE-2026-61500 CVSS score: 9.3, a case of session forgery stemming from the use of a weak pseudo-random number generator PRNG that c...

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...
