Meteor Slides versions up to 1.5.7 contain a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows attackers with high privileges to inject malicious scripts that execute when other users view the affected pages. The vulnerability has a CVSS 3.1 base score of 5.9, reflecting medium severity with network attack vector, low attack complexity, required privileges, and user interaction. No known exploits are reported in the wild, and no patch information is provided in the available data.

Successful exploitation can lead to limited confidentiality, integrity, and availability impacts by executing malicious scripts in the context of affected users. The attack requires high privileges and user interaction, which limits the ease of exploitation. There are no known active exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit user privileges to reduce risk and avoid accepting untrusted input in Meteor Slides. Monitor official Josh Leuze or Meteor Slides channels for updates and apply any released patches promptly.
