SCA: security update for mediawiki/core (GHSA-h8qx-mj6v-2934)

medium Tenable Cloud Security Plugin ID 437058

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- An issue was discovered in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. The non-
jqueryMsg version of mw.message().parse() doesn't escape HTML. This affects both message contents (which
are generally safe) and the parameters (which can be based on user input). (When jqueryMsg is loaded, it
correctly accepts only whitelisted tags in message contents, and escapes all parameters. Situations with
an unloaded jqueryMsg are rare in practice, but can for example occur for Special:SpecialPages on a wiki
with no extensions installed.) (CVE-2020-25828)
