CVE-2025-54236: Adobe Commerce and Magento Improper Input Validation Vulnerability

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run Adobe Commerce and Magento. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-10-24, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-11-14; treat that as the outer limit, not the target.
• EPSS 94.7%, percentile 99.9: FIRST’s model estimates a 94.7% chance of exploitation activity in the next 30 days, higher than 99.9% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes magento/community-edition (Composer (PHP)) <= 2.4.5-p14, no fixed version listed; magento/community-edition (Composer (PHP)) = 2.4.6, no fixed version listed; magento/community-edition (Composer (PHP)) >= 2.4.6-p1, <= 2.4.6-p12, no fixed version listed; magento/community-edition (Composer (PHP)) = 2.4.5, no fixed version listed. Check your lockfile, including transitive dependencies.
