# CVE-2024-34102: Adobe Commerce and Magento Open Source Improper Restriction of XML External Entity Reference (XXE) Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Adobe Commerce and Magento Open Source. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-07-17, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-08-07 ; treat that as the outer limit, not the target.
- EPSS 100.0% , percentile 100.0: FIRST’s model estimates a 100.0% chance of exploitation activity in the next 30 days, higher than 100.0% 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)) = 2.4.4, no fixed version listed ; magento/community-edition (Composer (PHP)) >= 2.4.6-p1, < 2.4.6-p6, fixed in 2.4.6-p6 ; magento/community-edition (Composer (PHP)) >= 2.4.5-p1, < 2.4.5-p8, fixed in 2.4.5-p8 ; magento/community-edition (Composer (PHP)) < 2.4.4-p9, fixed in 2.4.4-p9 . Check your lockfile, including transitive dependencies.
