May 28, 2023

Package : rainloop
Version : 1.12.1-2+deb10u1
CVE ID : CVE-2019-13389 CVE-2022-29360
Debian Bug : 1004548

Cross-site scripting (XSS) vulnerabilities were found in rainloop, a
web-based email client, which could lead to information disclosure
including passphrase leak.


It was discovered that RainLoop Webmail lacked XSS protection
mechanisms such as xlink:href validation, the X-XSS-Protection
header, and the Content-Security-Policy header.


Simon Scannell discovered that RainLoop's Email Viewer allows XSS
via a crafted text/html email message.

For Debian 10 buster, these problems have been fixed in version

We recommend that you upgrade your rainloop packages.
