Description (CNA)
Some HTML elements, such as <title> and <textarea>, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.

| Mozilla / Firefox | affected unspecified before 69 |
| Mozilla / Thunderbird | affected unspecified before 68.1; affected unspecified before 60.9 |
| Mozilla / Firefox ESR | affected unspecified before 60.9; affected unspecified before 68.1 |
