CVE-2019-12970
XSS was discovered in SquirrelMail through 1.4.22 and 1.5.x through 1.5.2.
Does this matter?
Lower severity and a low EPSS score (1.82%). Track it; it rarely justifies an emergency change on its own.
Description
XSS was discovered in SquirrelMail through 1.4.22 and 1.5.x through 1.5.2. Due to improper handling of RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be bypassed. Malicious script content from HTML e-mail can be executed within the application context via crafted use of (for example) a NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA element.
