CVE-2022-28202 1 Mediawiki 1 Mediawiki 2022-06-26 4.3 MEDIUM 6.1 MEDIUM
An XSS issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. The widthheight, widthheightpage, and nbytes properties of messages are not escaped when used in galleries or Special:RevisionDelete.
CVE-2021-30159 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2022-05-27 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Users can bypass intended restrictions on deleting pages in certain "fast double move" situations. MovePage::isValidMoveTarget() uses FOR UPDATE, but it's only called if Title::getArticleID() returns non-zero with no special flags. Next, MovePage::moveToInternal() will delete the page if getArticleID(READ_LATEST) is non-zero. Therefore, if the page is missing in the replica DB, isValidMove() will return true, and then moveToInternal() will unconditionally delete the page if it can be found in the master.
CVE-2022-29906 1 Mediawiki 1 Mediawiki 2022-05-10 7.5 HIGH 9.8 CRITICAL
The admin API module in the QuizGame extension for MediaWiki through 1.37.2 (before 665e33a68f6fa1167df99c0aa18ed0157cdf9f66) omits a check for the quizadmin user.
CVE-2022-29905 1 Mediawiki 1 Mediawiki 2022-05-10 4.3 MEDIUM 4.3 MEDIUM
The FanBoxes extension for MediaWiki through 1.37.2 (before 027ffb0b9d6fe0d823810cf03f5b562a212162d4) allows Special:UserBoxes CSRF.
CVE-2022-29904 1 Mediawiki 1 Mediawiki 2022-05-10 7.5 HIGH 9.8 CRITICAL
The SemanticDrilldown extension for MediaWiki through 1.37.2 (before e688bdba6434591b5dff689a45e4d53459954773) allows SQL injection with certain '-' and '_' constraints.
CVE-2022-29903 1 Mediawiki 1 Mediawiki 2022-05-10 4.3 MEDIUM 4.3 MEDIUM
The Private Domains extension for MediaWiki through 1.37.2 (before 1ad65d4c1c199b375ea80988d99ab51ae068f766) allows CSRF for editing pages that store the extension's configuration. The attacker must trigger a POST request to Special:PrivateDomains.
CVE-2022-28323 1 Mediawiki 1 Mediawiki 2022-05-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in MediaWiki through 1.37.2. The SecurePoll extension allows a leak because sorting by timestamp is supported,

The Nimbus skin for MediaWiki through 1.37.2 (before 6f9c8fb868345701d9544a54d9752515aace39df) allows XSS in Advertise link messages.
CVE-2020-35480 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2022-04-08 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in MediaWiki before 1.35.1. Missing users (accounts that don't exist) and hidden users (accounts that have been explicitly hidden due to being abusive, or similar) that the viewer cannot see are handled differently, exposing sensitive information about the hidden status to unprivileged viewers. This exists on various code paths.
CVE-2020-35477 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2022-04-08 5.0 MEDIUM 5.3 MEDIUM
MediaWiki before 1.35.1 blocks legitimate attempts to hide log entries in some situations. If one sets MediaWiki:Mainpage to Special:MyLanguage/Main Page, visits a log entry on Special:Log, and toggles the "Change visibility of selected log entries" checkbox (or a tags checkbox) next to it, there is a redirection to the main page's action=historysubmit (instead of the desired behavior in which a revision-deletion form appears).
CVE-2020-35475 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2022-04-08 5.0 MEDIUM 7.5 HIGH
In MediaWiki before 1.35.1, the messages userrights-expiry-current and userrights-expiry-none can contain raw HTML. XSS can happen when a user visits Special:UserRights but does not have rights to change all userrights, and the table on the left side has unchangeable groups in it. (The right column with the changeable groups is not affected and is escaped correctly.)
CVE-2022-28209 1 Mediawiki 1 Mediawiki 2022-04-05 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Mediawiki through 1.37.1. The check for the override-antispoof permission in the AntiSpoof extension is incorrect.
CVE-2022-28206 1 Mediawiki 1 Mediawiki 2022-04-05 7.5 HIGH 9.8 CRITICAL
An issue was discovered in MediaWiki through 1.37.1. ImportPlanValidator.php in the FileImporter extension mishandles the check for edit rights.
CVE-2022-28205 1 Mediawiki 1 Mediawiki 2022-04-05 7.5 HIGH 9.8 CRITICAL
An issue was discovered in MediaWiki through 1.37.1. The CentralAuth extension mishandles a ttl issue for groups expiring in the future.
CVE-2019-16738 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2022-03-31 5.0 MEDIUM 5.3 MEDIUM

CVE-2017-0371 1 Mediawiki 1 Mediawiki 2022-02-28 5.0 MEDIUM 7.5 HIGH
MediaWiki before 1.23.16, 1.24.x through 1.27.x before 1.27.2, and 1.28.x before 1.28.1 allows remote attackers to discover the IP addresses of Wiki visitors via a style="background-image: attr(title url);" attack within a DIV element that has an attacker-controlled URL in the title attribute.
CVE-2021-45471 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2022-02-07 5.0 MEDIUM 5.3 MEDIUM
In MediaWiki through 1.37, blocked IP addresses are allowed to edit EntitySchema items.
CVE-2021-45472 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2022-02-07 4.3 MEDIUM 6.1 MEDIUM
In MediaWiki through 1.37, XSS can occur in Wikibase because an external identifier property can have a URL format that includes a $1 formatter substitution marker, and the javascript: URL scheme (among others) can be used.
CVE-2021-45473 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2022-02-07 4.3 MEDIUM 6.1 MEDIUM
In MediaWiki through 1.37, Wikibase item descriptions allow XSS, which is triggered upon a visit to an action=info URL (aka a page-information sidebar).

In MediaWiki through 1.37, the Special:ImportFile URI (aka FileImporter) allows XSS, as demonstrated by the clientUrl parameter.
