Articles & Coverage 1
AnalysisAI
Privilege escalation in Adobe Commerce and Magento Open Source (including Adobe Commerce B2B) lets a remote attacker gain elevated access to sensitive resources through an incorrect authorization flaw, with no user interaction required. All supported branches from 2.4.4 through 2.4.9 (and B2B 1.3.3-1.5.3) prior to the August 2026 patch set are affected, and the CVSS 9.1 rating reflects high confidentiality and integrity impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions beyond network reachability - remote unauthenticated exploitation (PR:N/UI:N/AC:L) against affected Adobe Commerce, Magento Open Source, and Adobe Commerce B2B versions prior to the August 2026 patches; the target's storefront or admin/API surface must be reachable by the attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are internally consistent and point to a genuine priority rather than an inflated high-CVSS score: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) describes a network-reachable, low-complexity, unauthenticated attack with high confidentiality and integrity impact, matching the description's statement that exploitation requires no user interaction and yields elevated access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade to the August 2026 fixed builds - Adobe Commerce 2.4.9-2026-aug, 2.4.8-2026-aug, 2.4.7-2026-aug, 2.4.6-2026-aug, 2.4.5-2026-aug, or 2.4.4-2026-aug; Magento Open Source 2.4.9-2026-aug, 2.4.8-2026-aug, 2.4.7-2026-aug, or 2.4.6-2026-aug; and Adobe Commerce B2B 1.5.3-2026-aug, 1.5.2-2026-aug, 1.4.2-2026-aug, 1.3.4-2026-aug, or 1.3.3-2026-aug, as directed by Adobe advisory APSB26-92 (https://helpx.adobe.com/security/products/magento/apsb26-92.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
