CVE-2020-6798
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed.
Impact
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
Affected products
| Vendor | Product | Affected versions |
|---|---|---|
| Mozilla | Firefox | before 73.0 |
| Mozilla | Firefox Esr | before 68.5.0 |
| Mozilla | Thunderbird | before 68.5.0 |
