Description

Security researcher vsemozhetbyt reported that when the DOMParser is used to parse text/html data in a Firefox extension, linked resources within this HTML data will be loaded. If the data being parsed in the extension is untrusted, it could lead to information leakage and can potentially be combined with other attacks to become exploitable.
