Vulnerability Title
Plunk: Stored XSS in campaign view
Source: CVE Program / CVE List V5
Vulnerability Description
Plunk is an open-source email platform built on top of AWS SES. Prior to version 0.9.0, a stored cross-site scripting (XSS) vulnerability exists in the campaign management feature, where the email body content created by authenticated project members is stored and later rendered in the admin dashboard using React's dangerouslySetInnerHTML without any HTML sanitization. This allows a lower-privileged member to embed malicious scripts in a campaign's email body that execute in the context of any admin or other member who views the campaign, potentially enabling session hijacking or unauthorized actions on their behalf. This issue has been patched in version 0.9.0.
