CyberRota Analysis
AI-GeneratedThe Plane project management tool prior to version 1.4.0 is vulnerable to an HTML injection flaw that allows any authenticated user to insert arbitrary HTML into a project, potentially leading to JavaScript execution in the context of other users' sessions. This can result in the exfiltration of sensitive API tokens when project members interact with the compromised content. Organizations using affected versions should prioritize upgrading to 1.4.0 to mitigate this high-severity risk.

Original NVD Description
Plane is an open-source project management tool. Prior to 1.4.0, IntakeIssuePublicViewSet.create in Plane v1.3.1 writes description_html through Issue.objects.create(...) without calling validate_html_content from nh3. Any authenticated user, including a new user with no workspace memberships, can plant arbitrary HTML in a project that has a published DeployBoard with intake enabled. When a project member or viewer of a closed intake item clicks the planted link, the TipTap \tjavascript: parser bypass and the target="_self" click handler execute JavaScript in the viewer's session and exfiltrate a long-lived API token. This issue is fixed in 1.4.0.
