CVE-2025-55757MediumCVSS 6.1CVE published 25 October 2025Added to mySites.guru 9 April 2026

VirtueMart (com_virtuemart) below 4.4.11 - Unauthenticated Reflected XSS and Authenticated SQL Injection

VirtueMart e-commerce component. CVE-2025-55757 (unauthenticated reflected XSS, affects 1.0.0-4.4.10) and CVE-2025-25228 (authenticated SQL injection in product management, affects 1.0.0-4.4.7). Fixed in 4.4.11. Rule pinned to component type because the Xmap and OSMap VirtueMart bridge plugins ship under element com_virtuemart at their own low versions. Also within this rule: CVE-2023-54362 (VirtueMart Cart 4.0.12 reflected XSS), which sits below this ceiling and needs no separate row.
