The vulnerability affects the Markdown File Handler component and can be exploited remotely. The issue was discovered and disclosed publicly, with the vendor being contacted but providing no response (NVD).

The vulnerability is classified as a cross-site scripting (XSS) issue with a CVSS v3.1 base score of 6.1 (MEDIUM) and vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N.

When exploited, this vulnerability allows attackers to execute cross-site scripting attacks, potentially leading to unauthorized access to sensitive information and manipulation of web content. The impact is particularly significant as it can bypass the application's built-in XSS protection mechanisms, even when configured at the highest security level (NVD).

At the time of disclosure, no official fixes have been provided by the vendor. The vendor was contacted about this vulnerability but did not respond to the disclosure (NVD).
