CVE-2023-4547Public exploitNetwork attack vector

Script execution via unneutralized search filters

Published Aug 26, 2023 · Updated Aug 2, 2024

Cross-site scripting in SPA-Cart 1.9.0.3 allows attackers to run script in a victim's browser through crafted search-filter values. The /search handler places filter[brandid] or filter[price] input into the generated page without adequate output neutralization. Exploitation requires a victim to open the crafted request, after which script runs in the SPA-Cart origin and can act on browser-accessible site data.
