Description The issue arises from the mishandling of a note's title when the batch feature is triggered, leading to XSS. This, in turn, results in remote code execution due to Node integration.

Recommendations For versions prior to 2.6.3, update to version 2.6.3 or later to resolve the issue. As a temporary workaround, consider disabling the batch feature until a patch is available. Restrict access to notes with potentially malicious titles to minimize the risk of exploitation.
