The Text Prompter WordPress plugin suffers from a stored XSS vulnerability (CWE-79) in its 'text_prompter' shortcode. This flaw arises from improper neutralization of input during web page generation, allowing authenticated contributors or higher to inject malicious scripts. These scripts execute in the context of users who visit the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 1.0.7. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or vendor advisory is currently available to confirm remediation status.

An attacker with contributor-level access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who view the infected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the plugin if possible to prevent exploitation.
