EPSS

• CVE-2026-47416: 0.26% estimated exploitation activity in the next 30 days; percentile 18.36 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary Type: 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. File: src/praisonai-platform/praisonaiplatform/api/routes/workspaces.py, lines 115-127; services/memberservice.py, lines 55-69; api/deps.py, lines 54-73. Root cause: requireworkspacemember exists with a minrole parameter (deps.py:58) but FastAPI's Depends(requireworkspacemember) cannot pass arguments, so every route uses the default "member". The route then passes the URL-supplied userid and the body-supplied role…

# Patch Next advisory brief: CVE-2026-47416

Advisory: praisonai-platform: Any workspace member can promote themselves or others to owner via PATCH /workspaces/{id}/members/{user_id}
IDs: CVE-2026-47416, GHSA-c2m8-4gcg-v22g
Record: https://patchnext.com/advisories/cve-2026-47416 (revision 3, source checked 26 Oct 2026, 13:41 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonai-platform 0.1.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonai-platform: affected <= 0.1.2; fixed in 0.1.4

## Suggested inspection (read-only)
- `python -m pip show praisonai-platform`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on praisonai-platform.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

- Verified: https://github.com/advisories/GHSA-c2m8-4gcg-v22g (GitHub-reviewed advisory GHSA-c2m8-4gcg-v22g lists affected ranges: PyPI praisonai-platform >=0 <=0.1.2)
