The fresh Podcaster WordPress plugin suffers from a stored Cross-Site Scripting vulnerability (CWE-79) in all versions up to and including 1.0.7. The issue arises from improper neutralization of user-supplied attributes in the 'freshpodcaster' shortcode, allowing authenticated attackers with contributor-level privileges or higher to inject arbitrary web scripts. These scripts persist in pages and execute when accessed by other users, potentially leading to session hijacking or other client-side impacts. The CVSS 3.1 score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact. No known exploits in the wild or vendor patches have been reported as of the publication date.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the 'freshpodcaster' shortcode. This can lead to unauthorized script execution in the context of users visiting the infected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not impact availability. The CVSS score of 6.4 indicates a medium severity impact primarily affecting confidentiality and integrity.

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 removing or disabling the fresh Podcaster plugin if possible to prevent exploitation.
