Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Through a malicious URL that contained a quote character it was possible to inject HTML code in KMail's plaintext viewer. Due to the parser used on the URL it was not possible to include the equal sign (=) or a space into the injected HTML, which greatly reduces the available HTML functionality. Although it is possible to include an HTML comment indicator to hide content.
