CVE-2026-47410 MervinPraison CVE debrief

CVE-2026-47410 is a critical vulnerability in PraisonAI Platform versions prior to 0.1.4. The platform's JWT signing secret defaults to a hardcoded literal 'dev-secret-change-me' when PLATFORM_JWT_SECRET is unset. A safety check exists but only fires when PLATFORM_ENV != 'dev'; the default value of PLATFORM_ENV is 'dev', so the check is silently bypassed in any deployment that does not explicitly opt out. This allows an attacker to read the literal from a public source file, mint a JWT with arbitrary sub and email claims, and authenticate as any existing user, including workspace owners and admins. The vulnerability has a CVSS score of 9.8 and is considered critical.

Who should care

Users of PraisonAI Platform versions prior to 0.1.4 should be aware of this critical vulnerability and take immediate action to upgrade to version 0.1.4 or later. Additionally, administrators and users of PraisonAI Platform should be cautious of potential authentication bypass attacks and review compensating controls for exposed systems while remediation is scheduled and verified.

Technical summary

The PraisonAI Platform has an insecure default cryptographic key in versions prior to 0.1.4. The JWT signing secret is hardcoded to 'dev-secret-change-me' when PLATFORM_JWT_SECRET is not set. This allows attackers to authenticate as any user, including administrators, by generating a JWT with arbitrary claims. The vulnerability has a CVSS score of 9.8 and is considered critical. A safety check exists but only fires when PLATFORM_ENV != 'dev'; the default value of PLATFORM_ENV is 'dev', so the check is silently bypassed in any deployment that does not explicitly opt out.

Defensive priority

High

Recommended defensive actions

  • Upgrade to PraisonAI Platform version 0.1.4 or later
  • Set a secure value for PLATFORM_JWT_SECRET
  • Verify PLATFORM_ENV is set correctly
  • Monitor for suspicious authentication activity
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
