Adobe Commerce account flaw drew attacks after disclosure

Sansec reported blocking the first attempts to exploit a critical Adobe Commerce flaw shortly after Adobe disclosed it in August 2026. CVE-2026-71362 affects Commerce, Commerce B2B, and Magento Open Source versions through the July 2026 patches.

The authorization flaw lets a remote attacker without an account make a customer session appear to belong to another customer, exposing that person’s account and private data. Adobe said it had no evidence of in-the-wild exploitation; Sansec’s report describes attempts, not confirmed account compromises.

Adobe says its isolated patch is designed to reduce delays caused by integration issues. For stores still testing deployment, the gap after disclosure is an exposure window; retailers on other storefront platforms face the same timing risk when a fix prompts immediate testing by attackers.
