• CVE-2026-47406: 0.41% estimated exploitation activity in the next 30 days; percentile 35.57 (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: Insecure Direct Object Reference. The dependency endpoints (POST/GET /workspaces/{workspaceid}/issues/{issueid}/dependencies and DELETE .../dependencies/{depid}) gate access on requireworkspacemember(workspaceid) only, then dispatch to DependencyService calls that take URL/body-supplied issue and dependency IDs without verifying any of them belong to the membership-checked workspace. Most damaging: createdependency accepts body.dependsonissueid from the request body — that ID is checked against nothing — letting an attacker create a "blocks" or "related" link between any two issues anywhere in the database. File: src/praisonai-platform/praisonaiplatform/api/routes/dependencies.py, lines 22-58; services/dependencyservice.py, lines 26-65. Root cause: the same Depends(requireworkspacemember) default-min-role pattern as the companion IDORs, plus a service layer (DependencyService) where every method takes raw IDs and queries them directly. create(issueid, dependsonissueid,…

# Patch Next advisory brief: CVE-2026-47406

Advisory: praisonai-platform: IDOR in dependency endpoints allows cross-workspace issue linking, reading, and deletion due to missing ownership checks
IDs: CVE-2026-47406, GHSA-4x6r-9v57-3gqw
Record: https://patchnext.com/advisories/cve-2026-47406 (revision 2, 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: High (CVSS 8.1)
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.
