How do I fix CVE-2024-40633?

Update sylius/sylius to 1.12.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-40633 is resolved across your whole dependency graph.

How do I detect CVE-2024-40633 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sylius/sylius. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2024-40633 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2024-40633?

O3 pinpoints whether CVE-2024-40633 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-40633 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-40633 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-40633?

CVE-2024-40633 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 30th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-40633?

Description

Sylius is an Open Source eCommerce Framework on Symfony. A security vulnerability was discovered in the /api/v2/shop/adjustments/{id} endpoint, which retrieves order adjustments based on incremental integer IDs. The vulnerability allows an attacker to enumerate valid adjustment IDs and retrieve order tokens. Using these tokens, an attacker can access guest customer order details - sensitive guest customer information. The issue is fixed in versions: 1.12.19, 1.13.4 and above. The /api/v2/shop/adjustments/{id} will always return 404 status. Users are advised to upgrade. Users unable to upgrade may alter their config to mitigate this issue. Please see the linked GHSA for details.
