Datavane Datavines JWT Token TokenManager.java hard-coded key
Summary
A vulnerability was determined in Datavane Datavines up to 13607645e14a4982468cfdbcf75c85cde63bae71. 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 . 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.

Title
Hard-coded Cryptographic Key in Watchfire Controllers
Summary
The affected Watchfire Controller Software contains self-signed hard-coded RSA private keys and corresponding X.509 certificates used for authenticating and encrypting HTTPS/TLS connections to the controller's built-in web management interface.

CVE-2026-5622 (GCVE-0-2026-5622)

Vulnerability from cvelistv5 – Published: 2026-04-06 04:30 – Updated: 2026-04-07 03:01
VLAI
Title
hcengineering Huly Platform JWT Token token.ts hard-coded key
Summary
A vulnerability was determined in hcengineering Huly Platform 0.7.382. Affected by this issue is some unknown functionality of the file foundations/core/packages/token/src/token.ts of the component JWT Token Handler. This manipulation of the argument SERVER_SECRET with the input secret causes use of hard-coded cryptographic key . The attack can be initiated remotely. The attack is considered to have high complexity. The exploitation is known to be difficult. The vendor was contacted early about this disclosure but did not respond in any way.
