# CVE-2026-47416: praisonai-platform: Any workspace member can promote themselves or others to owner via PATCH /workspaces/{id}/members/{user_id}

**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) <= 0.1.2, 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 are vulnerable to vertical privilege escalation. The PATCH /workspaces/{workspaceid}/members/{userid} endpoint is gated by requireworkspacemember(workspaceid), which defaults to minrole="member" and is never overridden by the route. The handler then calls MemberService.updaterole(workspaceid, userid, body.role) which sets the target member's role to whatever the request body specifies, with no check that the caller has owner-or-admin privilege, no check that the new role is not higher than the caller's own, and no check that the caller is not silently promoting themselves. PraisonAI Platform version 0.1.4 patches the issue.

## Affected packages

- PyPI `praisonai-platform` <= 0.1.2 → 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.
