CVE-2025-14261NVD status: Deferred

litmus: Insufficient Entropy

CVE-2025-14261 is a high-severity insufficient entropy vulnerability in litmus from LitmusChaos, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 3.23.0 as the first without the flaw, so updating litmus to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

Official description

The Litmus platform uses JWT for authentication and authorization, but the secret being used for signing the JWT is only 6 bytes long at its core, which makes it extremely easy to crack.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Insufficient Entropy

The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

How developers prevent this class of flaw

  • Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
