CVE-2021-39355Public exploitNetwork attack vector

Stored script execution via unsanitized plugin parameters

Published Oct 19, 2021 · Updated Feb 14, 2025

Stored XSS in Shambhu Prasad Patnaik Indeed Job Importer 1.0.5 and earlier allows remote authenticated users to inject scripts via plugin parameters. The plugin processes several administrator-supplied parameters in indeed-job-importer.php without sufficient validation or sanitization, allowing script content to persist in generated pages. The path requires administrative access and applies where unfiltered_html is disabled, including multisite installations; injected script executes in the site origin.
