# CVE-2026-47413: praisonai-platform: Any workspace member can add arbitrary user as owner via POST /workspaces/{id}/members

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (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 0.4% , percentile 29: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 29% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes praisonai-platform (PyPI) < 0.1.4, fixed in 0.1.4 . Check your lockfile, including transitive dependencies.

## What it is

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have aprivilege escalation / cross-tenant member injection. The POST /workspaces/{workspaceid}/members endpoint is gated only by requireworkspacemember(workspaceid) (default minrole="member") and forwards the request body's userid and role straight into MemberService.add(workspaceid, userid, role), which has no caller-permission check. A user with the lowest workspace privilege can add any user (including a new attacker-controlled second account, or an existing account they want to grief) as owner of the workspace. PraisonAI Platform version 0.1.4 patches the issue.

## Affected packages

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

## Affected products (CVE record)

- MervinPraison praisonai-platform: < 0.1.4

## Severity

- GitHub_M CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.36% probability of exploitation activity in the next 30 days; percentile 29.
