• CVE-2026-44585: 0.29% estimated exploitation activity in the next 30 days; percentile 21.08 (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 The ticket creation endpoint accepts a user-supplied service identifier without enforcing ownership validation, allowing authenticated users to create support tickets referencing services belonging to other accounts by modifying the service ID in the request. Technical Details The ticket creation endpoint accepted a user-supplied service identifier without verifying ownership or authorization against the authenticated account. An attacker could modify the service ID value in the client-side request and successfully create a ticket associated with another user's service. The vulnerability required authentication and did not provide direct access to service contents or customer data. However, referenced service information could become visible to support personnel handling the ticket. Impact Successful exploitation could allow an authenticated user to: - Create support tickets referencing services belonging to other users - Potentially cause support staff to interact with or…

# Patch Next advisory brief: CVE-2026-44585

Advisory: Paymenter has broken object level authorization via service reference manipulation on ticket creation
IDs: CVE-2026-44585, GHSA-x93q-x9pc-w5hw
Record: https://patchnext.com/advisories/cve-2026-44585 (revision 1, source checked 26 Oct 2026, 14:49 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: paymenter/paymenter 1.5.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist paymenter/paymenter: affected < 1.5.0; fixed in 1.5.0

## Suggested inspection (read-only)
- Packagist paymenter/paymenter: 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 paymenter/paymenter.
- 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-x93q-x9pc-w5hw (GitHub-reviewed advisory GHSA-x93q-x9pc-w5hw lists affected ranges: Packagist paymenter/paymenter >=0 <1.5.0)
