The affected element is an unknown function of the file datavines-core/src/main/java/io/datavines/core/utils/TokenManager.java of the component JWT Token Handler. Executing a manipulation of the argument tokenSecret can lead to use of hard-coded cryptographic key\r . The attack can be executed remotely. The attack requires a high level of complexity. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. This patch is called e540d6dc04e2e6ad11907fb655f3728a13e7b939. It is advisable to implement a patch to correct this issue. The project was informed of the problem early through a pull request but has not reacted yet."
