DescriptionCVE.org

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in snstheme Samex - Clean, Minimal Shop WooCommerce WordPress Theme and snstheme M.Anh - Fashion WooCoommerce WordPress Theme allows Reflected XSS.

This issue affects Samex - Clean, Minimal Shop WooCommerce WordPress Theme: from n/a through 2.5; M.Anh - Fashion WooCoommerce WordPress Theme: from n/a through 1.7.

AnalysisAI

Reflected cross-site scripting in two snstheme WooCommerce WordPress themes - Samex (through version 2.5) and M.Anh (through version 1.7) - permits unauthenticated remote attackers to inject and execute arbitrary JavaScript in a victim's browser by delivering a specially crafted URL that the theme reflects back unsanitized into the HTML response. The scope change (S:C) in the CVSS vector indicates that successful exploitation extends impact beyond the WordPress application into the victim's browser origin, enabling session hijacking or administrative account compromise. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target WordPress installation has either the Samex theme at version 2.5 or earlier, or the M.Anh theme at version 1.7 or earlier, set as the active theme, and that the WooCommerce plugin is installed and active. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 7.1 reflects a network-reachable, low-complexity reflected XSS with no privilege requirement on the attacker side (PR:N), but the mandatory victim interaction (UI:R) meaningfully caps real-world exploitability relative to a stored or DOM-based variant. … 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 The primary remediation is to update each affected theme to a version released after the stated vulnerability ceiling - Samex beyond version 2.5 and M.Anh beyond version 1.7 - if patched releases have been issued by snstheme. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit your WordPress environment to identify any active deployments of Samex (version 2.5 or earlier) or M.Anh (version 1.7 or earlier) and assess their public-facing exposure. …
