# CVE-2026-57147: praisonai-platform: default JWT signing secret 'dev-secret-change-me' enables token forgery

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.8% , percentile 55: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 55% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes praisonai-platform (PyPI) <= 0.1.4, fixed in 0.1.6 . Check your lockfile, including transitive dependencies.

## What it is

PraisonAI is a multi-agent teams system. Prior to 0.1.6, praisonaiplatform/services/authservice.py assigns the public dev-secret-change-me value to JWTSECRET when PLATFORMJWTSECRET is unset, and its production guard does not run when PLATFORMENV is also unset because that setting defaults to dev. A remote unauthenticated attacker can mint an HS256 token with an arbitrary sub and email, and the platform's AuthService.verifytoken() and getcurrentuser dependency accept the forged identity for protected API routes. This vulnerability is fixed in praisonai-platform 0.1.6.

## Affected packages

- PyPI `praisonai-platform` <= 0.1.4 → fixed: 0.1.6

## Affected products (CVE record)

- MervinPraison PraisonAI: < 4.6.51
- MervinPraison praisonai-platform: < 0.1.6

## Severity

- GitHub_M CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.77% probability of exploitation activity in the next 30 days; percentile 55.
