CVE-2020-26229
|
| Summary | XML External Entity in Dashboard Widget ### Problem It has been discovered that RSS widgets are susceptible to XML external entity processing. This vulnerability is reasonable, but is theoretical - it was not possible to actually reproduce the vulnerability with current PHP versions of supported and maintained system distributions. At least with _libxml2_ version 2.9, the processing of XML external entities is disabled per default - and cannot be exploited. Besides that, a valid backend user account is needed. ### Solution Update to TYPO3 version 10.4.10 that fixes the problem described. |
