CVE-2024-34103: Magento Open Source Improper Authentication vulnerability

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 0.9%, percentile 60: FIRST’s model estimates a 0.9% chance of exploitation activity in the next 30 days, higher than 60% of all scored CVEs (moderate). 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)) = 2.4.7, no fixed version listed; magento/community-edition (Composer (PHP)) = 2.4.6, no fixed version listed; magento/community-edition (Composer (PHP)) = 2.4.5, no fixed version listed; magento/community-edition (Composer (PHP)) = 2.4.4, no fixed version listed. Check your lockfile, including transitive dependencies.
