CVE-2025-54236
Adobe Commerce and Magento Open Source contain an improper input validation vulnerability that could allow an attacker to take over customer accounts through the Commerce REST API.
What this means for your business
- It affects Adobe Commerce and Magento. It matters if your company, or a supplier that handles your data, runs it.
- Attackers are already using it. CISA added it to its list of flaws used in real attacks on 24 October 2025.
- FIRST's prediction model gives it a 95% chance of attack attempts being seen in the next 30 days, ranking above 99% of all known flaws.
What to do
- 1Check whether your company or your suppliers run Adobe Commerce and Magento.
- 2If you do, follow CISA's required action below. No patch reference has been published yet.
- 3Treat it as urgent. US federal agencies must fix it by 14 November 2025. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
- 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
