Extendthemes

Extendthemes develops a focused portfolio of WordPress themes and page-builder plugins including Colibri, Materialis, and Calliope that serve website designers and small-business users. While the product count remains narrow, the vendor's vulnerabilities are widely relevant because WordPress plugins achieve significant landscape penetration and remain in service across many long-tail deployments. The recurring weakness classes—cross-site scripting, cross-site request forgery, missing authorization checks, and SQL injection—are endemic to web application and plugin development, reflecting the challenge of securing user input handling and privilege boundaries in dynamic plugin architectures. Defenders managing WordPress environments should monitor this vendor's patches closely despite its modest disclosures, since plugin vulnerabilities often escape automated update cycles on legacy or poorly maintained sites. Current exploitation activity and exposure counts are shown alongside this summary.
