• CVE-2025-55741: 0.44% estimated exploitation activity in the next 30 days; percentile 38.46 (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 In Unopim, it is possible to create roles and choose the privileges. However, users without the “Delete” privilege for Products cannot delete a single product via the standard endpoint (expected behavior), but can still delete products via the mass-delete endpoint, even when the request contains only one product ID. Severity: High CVSS Score 8.1 (CVSS 3.1 Vector: AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H) Category: Broken Access Control / Missing Authorization (OWASP A01:2021) Impact: Unauthorized product deletion - data loss, possible business disruption Affected Behavior Single delete (enforced): DELETE /admin/catalog/products/{id} returns 401 with "This action is unauthorized" for users lacking the Delete privilege. Mass delete (not enforced): POST /admin/catalog/products/mass-delete allows deletion without the Delete privilege. This occurs for both multiple IDs and a single ID submitted to the bulk endpoint.

# Patch Next advisory brief: CVE-2025-55741

Advisory: UnoPim has Broken Access Control
IDs: CVE-2025-55741, GHSA-8p2f-fx4q-75cx
Record: https://patchnext.com/advisories/cve-2025-55741 (revision 1, source checked 26 Oct 2026, 14:34 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: unopim/unopim 0.3.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist unopim/unopim: affected <= 0.3.0; fixed in 0.3.1

## Suggested inspection (read-only)
- Packagist unopim/unopim: check the installed version with your package manager.

## 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 unopim/unopim.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-8p2f-fx4q-75cx (GitHub-reviewed advisory GHSA-8p2f-fx4q-75cx lists affected ranges: Packagist unopim/unopim >=0 <=0.3.0)
