CVE-2026-21360
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Commerce versions 2.4.9-alpha3, 2.4.8-p3, 2.4.7-p8, 2.4.6-p13, 2.4.5-p15, 2.4.4-p16 and earlier are affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could result in a security feature bypass. A high-privileged attacker could leverage this vulnerability to access unauthorized files or directories outside the intended restricted path. Exploitation of this issue does not require user interaction.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Adobe Commerce versionCheck the composer.json file in the Magento root directory for the version entry under 'require' > 'magento/product-community-edition', or access the admin panel and navigate to System > About System to view the installed version.Affected if The installed version is 2.4.4, 2.4.5, 2.4.6, 2.4.7, 2.4.8, 2.4.9, or any version lower than 2.4.4
-
Identify installed Adobe Commerce B2b versionCheck the composer.json for 'magento/module-b2b' version entry, or look in the admin panel under Stores > Settings > Configuration > B2B Features if the B2B module is enabled.Affected if The installed B2b version is 1.3.3, 1.3.4, 1.3.5, 1.4.2, 1.5.2, 1.5.3, or any version lower than 1.3.3
-
Identify installed Adobe Magento versionCheck the composer.json for 'magento/magento2-base' version, or view the version from the admin panel at System > About System.Affected if The installed Magento version is 2.4.5, 2.4.6, 2.4.7, 2.4.8, 2.4.9, or any version lower than 2.4.5
