CVE-2021-40642
Textpattern CMS v4.8.7 and older vulnerability exists through Sensitive Cookie in HTTPS Session Without 'Secure' Attribute via textpattern/lib/txplib_misc.php.
Does this matter?
Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.
Description
Textpattern CMS v4.8.7 and older vulnerability exists through Sensitive Cookie in HTTPS Session Without 'Secure' Attribute via textpattern/lib/txplib_misc.php. The secure flag is not set for txp_login session cookie in the application. If the secure flag is not set, then the cookie will be transmitted in clear-text if the user visits any HTTP URLs within the cookie's scope. An attacker may be able to induce this event by feeding a user suitable links, either directly or via another web site.
