Description

A Brazilian Magecart group exploited a critical vulnerability (CVE-2026-8467) in Plausible Community Edition versions 3.0.0 through 3.2.0 to inject a card skimmer into the Plausible analytics script used by the Brazilian ecommerce platform Convertr. From October 24 to October 27, 2026, the malicious script stole payment card details, CVV, expiry dates, cardholder names, and CPF taxpayer numbers from shoppers during checkout. The stolen data was exfiltrated to the domain 1x0.is. Convertr removed the skimmer and patched the vulnerability on October 27. This Magecart group has targeted multiple Brazilian ecommerce platforms since 2024 using distinctive data exfiltration techniques.
