JupyterLab before 4.5.9 contains a stored cross-site scripting vulnerability in the Extension Manager that fails to validate URI protocols in package metadata URLs. Attackers can publish malicious PyPI packages with javascript: URLs in project metadata that execute arbitrary JavaScript in the JupyterLab origin when users click the extension name.

——4Plex Media Server before 1.43.3.10861 does not correctly neutralize URL values included in 'searchOne,' allowing an attacker to call other plugins' functions and supply their own parameters.4hCVE-2026-888596.3 MED43.5%
——13A flaw was found in Evolution. A remote attacker can exploit this vulnerability by sending a specially crafted HTML email containing a spoofed vCard control. When a victim clicks on this control, Evolution's trusted JavaScript handler incorrectly assigns an attacker-controlled JavaScript URL to an iframe's source. This action leads to arbitrary JavaScript execution within the mail-viewing context, effectively bypassing the security measures designed to prevent script execution in email content.40dCVE-2026-54443—28.9%
——9Dashy is a self-hostable personal dashboard. From 1.9.4 until 3.2.0, the Dashy RSS Widget in src/components/Widgets/RssFeed.vue does not sanitize RSS item link values before rendering feed item titles and Read More links as anchor href attributes, allowing an attacker-controlled feed to provide a javascript: URI that executes when clicked in the Dashy origin. This issue is fixed in version 3.2.0.97d
