• CVE-2026-68501: 0.87% estimated exploitation activity in the next 30 days; percentile 58.86 (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.

Impact Two unauthenticated Mollie shop endpoints look up orders by a sequential integer orderId with no ownership or session check. Chained, they expose customer PII. GET /{locale}/thank-you (PageRedirectController::thankYouAction, route syliusmollieshopthankyoupageredirect) loads the order with findOneBy(['id' = $orderId]) and returns a 302 whose Location header carries that order's tokenValue. Any orderId thus yields that order's token. A non-existent id dereferences null and returns a 500. The handler also writes the raw orderId into the session. GET /{locale}/get-code (QrCodeAction::fetchQrCodeFromOrder, route syliusmollieshopgetqrcode) runs the same lookup and returns the order's QR code and id as JSON, ignoring the session cart; this is where the front-end got the integer id. A bad id 500s here too. That tokenValue is the order's only access control. Passed to the Sylius core page GET /{locale}/register-after-checkout/{tokenValue} it returns a form pre-filled with the…

# Patch Next advisory brief: CVE-2026-68501

Advisory: Sylius Mollie Plugin has unauthenticated IDOR that leaks order token and customer PII
IDs: CVE-2026-68501, GHSA-x83g-979r-f5fh
Record: https://patchnext.com/advisories/cve-2026-68501 (revision 2, source checked 26 Oct 2026, 14:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: sylius/mollie-plugin 3.3.1, 3.2.4, 2.2.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist sylius/mollie-plugin: affected < 2.2.8; >= 3.0.0, < 3.2.4; >= 3.3.0, < 3.3.1; fixed in 2.2.8, 3.2.4, 3.3.1

## Suggested inspection (read-only)
- Packagist sylius/mollie-plugin: 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 sylius/mollie-plugin.
- 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.
