CVE-2024-53356 is a critical-severity flaw (CVSS 9.8) affecting co2scope, dcscope. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Weak JWT Secret vulnerabilitiy in EasyVirt DCScope <= 8.6.0 and CO2Scope <= 1.3.0 allows remote attackers to generate JWT for privilege escalation. The HMAC secret used for generating tokens is hardcoded as "somerandomaccesstoken". A weak HMAC secret poses a risk because attackers can use the predictable secret to create valid JSON Web Tokens (JWTs), allowing them access to important information and actions within the application.
