CVE-2017-5673
In the Kunena extension 5.0.2 through 5.0.4 for Joomla!, the forum message subject (aka topic subject) accepts JavaScript, leading to XSS.
Does this matter?
Lower severity and a low EPSS score (0.69%). Track it; it rarely justifies an emergency change on its own.
Description
In the Kunena extension 5.0.2 through 5.0.4 for Joomla!, the forum message subject (aka topic subject) accepts JavaScript, leading to XSS. Six files are affected: crypsis/layouts/message/item/default.php, crypsis/layouts/message/item/top/default.php, crypsis/layouts/message/item/bottom/default.php, crypsisb3/layouts/message/item/default.php, crypsisb3/layouts/message/item/top/default.php, and crypsisb3/layouts/message/item/bottom/default.php. This is fixed in 5.0.5.
