CVE-2026-16638 describes a stored XSS vulnerability in the Drupal Media Folders module caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that persist and execute when viewed by other users. The vulnerability affects all versions from 0.0.0 up to 1.0.8. The CVSS 3.1 base score is 6.1, indicating a medium severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts confidentiality and integrity with no availability impact.

Successful exploitation can lead to the execution of arbitrary scripts in the context of the victim's browser, potentially allowing theft of sensitive information or session hijacking. The impact is limited to confidentiality and integrity, with no direct availability impact. No known exploits are reported in the wild.

No explicit patch or remediation details are provided in the input data. Since the affected versions are up to but not including 1.0.8, upgrading to version 1.0.8 or later (if available) is implied as a mitigation.
