CRITICAL 9.1

DescriptionCVE.org

Adobe Commerce versions 2.4.9-alpha2, 2.4.8-p2, 2.4.7-p7, 2.4.6-p12, 2.4.5-p14, 2.4.4-p15 and earlier are affected by an Improper Input Validation vulnerability. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality, and integrity impact to high. Exploitation of this issue does not require user interaction.

AnalysisAI

Session hijacking in Adobe Commerce (Magento) 2.4.x through 2.4.9-alpha2 allows remote unauthenticated attackers to take over active user sessions via improper input validation, confirmed actively exploited (CISA KEV). With 73.72% EPSS score (99th percentile) and public exploit code available, this represents a critical, widespread threat to e-commerce platforms. Attackers gain unauthorized access to user accounts including administrative sessions without requiring victim interaction.

Technical ContextAI

Adobe Commerce (formerly Magento) is an enterprise e-commerce platform built on PHP/MySQL. This vulnerability stems from CWE-20 (Improper Input Validation) in the session management layer. The affected CPE range shows all 2.4.x releases from 2.4.4 baseline through 2.4.9-alpha2, including all security patches up to p15 in the 2.4.4 line, p14 in 2.4.5, p12 in 2.4.6, p7 in 2.4.7, and p2 in 2.4.8. The validation flaw allows manipulation of session tokens or identifiers through HTTP requests, bypassing authentication mechanisms that should prevent unauthorized session access. The network attack vector (AV:N) with low complexity (AC:L) indicates the vulnerability is exploitable through standard web protocols without requiring complex preconditions or race conditions.

RemediationAI

Upgrade immediately to patched versions released by Adobe in APSB25-88: Adobe Commerce 2.4.8-p3, 2.4.7-p8, 2.4.6-p13, 2.4.5-p15, or 2.4.4-p16 depending on your baseline version. The Experience League knowledge base article (experienceleague.adobe.com/en/docs/experience-cloud-kcs/kbarticles/ka-27397) provides deployment-specific upgrade procedures. For organizations unable to immediately patch, implement emergency compensating controls: enable IP allowlisting for administrative access (limits attack surface but breaks legitimate remote admin workflows), implement additional session validation through Web Application Firewall rules targeting suspicious session token patterns (requires WAF capability and custom rule development, may cause false positives), and enforce session timeout reduction to 15 minutes or less (degrades user experience but limits hijacked session lifespan). Monitor authentication logs for anomalous session creation patterns and unusual administrative actions. These mitigations reduce but do not eliminate risk; patching remains the only complete remediation given the unauthenticated network attack vector.
