CISA adds actively exploited Adobe Commerce and Magento remote-code-execution flaw CVE-2026-45247 to KEV catalog

CISA says attackers are exploiting a serious Adobe Commerce and Magento flaw that can let them take over vulnerable online store servers. The issue, CVE-2026-45247, is a remote-code-execution vulnerability, meaning an attacker can run their own commands on the target system from afar; CISA added it to the Known Exploited Vulnerabilities catalog, which federal agencies use to prioritize urgent fixes. Affected product and version details would follow Adobe’s advisory, and internet-exposed commerce systems are the most immediate concern.
Why it matters: Organizations running Adobe Commerce or Magento should treat this as urgent because CISA only adds bugs to KEV when there is evidence of real-world exploitation. For online stores, the risk can include site takeover, payment-data exposure, and malware implantation, so defenders should identify affected instances and patch or mitigate immediately.
