This vulnerability allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses a compromised page. Because the of the default WordPress validation, it is not possible to insert the payload directly but if the Cooked plugin is installed, it is possible to create a recipe post type (cp_recipe) and inject the payload in the title field. Version 2.0.5 contains a patch for the issue.","severity":{"version":"3.1","score":5.4,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00298,"percentile":0.22719,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2024-07-01T21:19:35Z","modified":"2026-06-17T07:41:41Z","products":[{"vendor":"axiomthemes","product":"basil"},{"vendor":"xjsv","product":"basil"}],"references":[{"url":"https://github.com/XjSv/Basil/security/advisories/GHSA-cr7v-8v2h-49vx","tags":["x_refsource_CONFIRM","x_transferred"]},{"url":"https://github.com/XjSv/Basil/commit/e2b1dbf1637d1ec2663f9aa1a563b02dc76a8146","tags":["x_refsource_MISC","x_transferred"]}],"sources":{"cve":[{"id":"CVE-2024-39310","title":"WordPress Basil Theme Authenticated (Contributor+) Persistent Cross-Site Scripting Vulnerability ","description":"The Basil recipe theme for WordPress is vulnerable to Persistent Cross-Site Scripting (XSS) via the `post_title` parameter in versions up to, and including, 2.0.4 due to insufficient input sanitization and output escaping.
