Description

  • (bug T76686) [SECURITY] thumb.php outputs wikitext message as raw HTML, which could lead to xss. Permission to edit MediaWiki namespace is required to exploit this.\r\n (bug T77028) [SECURITY] Malicious site can bypass CORS restrictions in $wgCrossSiteAJAXdomains in API calls if it only included an allowed domain as part of its name.\r\n (bug T74222) The original patch for T74222 was reverted as unnecessary.\r\n

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
