Package : epiphany-browser
Version : 3.32.1.2-3~deb10u3
CVE ID : CVE-2023-26081
Debian Bug : 1031727

It was discovered that there was a potential credential stealing
attack in epiphany-browser, the default GNOME web browser.

When using a sandboxed Content Security Policy (CSP) or the HTML
"iframe" tag, the sandboxed web content was trusted by the
main/surrounding resource. After this change, however, the password
manager is disabled entirely in this situations, so that the
untrusted web content cannot exfiltrate passwords.

For Debian 10 buster, this problem has been fixed in version
3.32.1.2-3~deb10u3.

We recommend that you upgrade your epiphany-browser packages.
