CVE-2026-112833: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Castos Seriously Simple Podcasting

This vulnerability in Castos Seriously Simple Podcasting (versions >=0 and <3.17.1) is due to improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). An attacker with low privileges and requiring user interaction could exploit this to execute arbitrary scripts in the context of the affected application, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, low privileges required, user interaction required, scope changed, and partial impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to partial disclosure of information, modification of data, and disruption of service. The vulnerability requires user interaction and low privileges, limiting but not eliminating risk.
