**Detection Method:** Kolega.dev Deep Code Scan | Attribute | Value | |---|---| | Location | packages/server/src/enterprise/utils/tempTokenUtils.ts:31-34 | | Practical Exploitability | Medium | | Developer Approver | faizan@kolega.ai | ### Description The encryption key for token encryption has a weak default value 'Secre$t' when TOKEN_HASH_SECRET environment variable is not set. ### Affected Code ``` const key = crypto .createHash('sha256') .update(process.env.TOKEN_HASH_SECRET || 'Secre$t') .digest() ``` ### Evidence The default value 'Secre$t' is hardcoded in the source code and is cryptographically weak. This key is used to encrypt user IDs and workspace IDs in JWT tokens. ### Impact Token forgery - attackers can decrypt and manipulate encrypted token metadata, potentially changing user IDs or workspace IDs to escalate privileges or access unauthorized data. ### Recommendation Require TOKEN_HASH_SECRET to be set as a strong random value in environment variables. Throw an error on startup if not configured. Use a minimum of 32 bytes of entropy. ### Notes The TOKEN_HASH_SECRET has a weak hardcoded default 'Secre$t' (lines 31-34 and 50-53). This secret is used t

What to do next

  1. investigate

    Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.

    Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
