    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.
