Cross-site scripting (XSS) vulnerability in the Parser::replaceInternalLinks2 method in MediaWiki before 1.23.15, 1.26.x before 1.26.4, and 1.27.x before 1.27.1 allows remote attackers to inject arbitrary web script or HTML via vectors involving replacement of percent encoding in unclosed internal links.
CVE-2016-6331 1 Mediawiki 1 Mediawiki 2025-04-20 5.0 MEDIUM 7.5 HIGH
ApiParse in MediaWiki before 1.23.15, 1.26.x before 1.26.4, and 1.27.x before 1.27.1 allows remote attackers to bypass intended per-title read restrictions via a parse action to api.php.
CVE-2012-4379 1 Mediawiki 1 Mediawiki 2025-04-20 4.3 MEDIUM 6.5 MEDIUM
MediaWiki before 1.18.5, and 1.19.x before 1.19.2 does not send a restrictive X-Frame-Options HTTP header, which allows remote attackers to conduct clickjacking attacks via an embedded API response in an IFRAME element.
CVE-2015-8627 1 Mediawiki 1 Mediawiki 2025-04-20 5.0 MEDIUM 5.3 MEDIUM
MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1 do not properly normalize IP addresses containing zero-padded octets, which might allow remote attackers to bypass intended access restrictions by using an IP address that was not supposed to have been allowed.
CVE-2017-8812 2 Debian, Mediawiki 2 Debian Linux, Mediawiki 2025-04-20 5.0 MEDIUM 5.3 MEDIUM
MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 allows remote attackers to inject > (greater than) characters via the id attribute of a headline.
CVE-2015-8009 1 Mediawiki 1 Mediawiki 2025-04-20 5.0 MEDIUM 9.8 CRITICAL
The MWOAuthDataStore::lookup_token function in Extension:OAuth for MediaWiki 1.25.x before 1.25.3, 1.24.x before 1.24.4, and before 1.23.11 does not properly validate the signature when checking the authorization signature, which allows remote registered Consumers to use another Consumer's credentials by leveraging knowledge of the credentials.
CVE-2017-8810 2 Debian, Mediawiki 2 Debian Linux, Mediawiki 2025-04-20 5.0 MEDIUM 7.5 HIGH
MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2, when a private wiki is configured, provides different error messages for failed login attempts depending on whether the username exists, which allows remote attackers to enumerate account names and conduct brute-force attacks via a series of requests.
CVE-2017-8815 2 Debian, Mediawiki 2 Debian Linux, Mediawiki 2025-04-20 5.0 MEDIUM 7.5 HIGH
The language converter in MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 allows attribute injection attacks via glossary rules.
CVE-2015-8008 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2025-04-20 5.0 MEDIUM 7.5 HIGH
The OAuth extension for MediaWiki improperly negotiates a new client token only over Special:OAuth/initiate, which allows attackers to bypass intended IP address access restrictions by making an API request with an existing token.
CVE-2015-8624 1 Mediawiki 1 Mediawiki 2025-04-20 6.8 MEDIUM 8.8 HIGH
The User::matchEditToken function in includes/User.php in MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1 does not perform token comparison in constant time before determining if a debugging message should be logged, which allows remote attackers to guess the edit token and bypass CSRF protection via a timing attack, a different vulnerability than CVE-2015-8623.
CVE-2015-8623 1 Mediawiki 1 Mediawiki 2025-04-20 6.8 MEDIUM 8.8 HIGH
The User::matchEditToken function in includes/User.php in MediaWiki before 1.23.12 and 1.24.x before 1.24.5 does not perform token comparison in constant time before returning, which allows remote attackers to guess the edit token and bypass CSRF protection via a timing attack, a different vulnerability than CVE-2015-8624.
CVE-2016-6332 1 Mediawiki 1 Mediawiki 2025-04-20 5.0 MEDIUM 7.5 HIGH
MediaWiki before 1.23.15, 1.26.x before 1.26.4, and 1.27.x before 1.27.1, when $wgBlockDisablesLogin is true, might allow remote attackers to obtain sensitive information by leveraging failure to terminate sessions when a user account is blocked.
CVE-2016-6335 1 Mediawiki 1 Mediawiki 2025-04-20 5.0 MEDIUM 7.5 HIGH
MediaWiki before 1.23.15, 1.26.x before 1.26.4, and 1.27.x before 1.27.1 does not generate head items in the context of a given title, which allows remote attackers to obtain sensitive information via a parse action to api.php.
CVE-2015-8626 1 Mediawiki 1 Mediawiki 2025-04-20 5.0 MEDIUM 9.8 CRITICAL
The User::randomPassword function in MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1 generates passwords smaller than $wgMinimalPasswordLength, which makes it easier for remote attackers to obtain access via a brute-force attack.
CVE-2015-8622 1 Mediawiki 1 Mediawiki 2025-04-20 4.3 MEDIUM 6.1 MEDIUM
Cross-site scripting (XSS) vulnerability in MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1, when is configured with a relative URL, allows remote authenticated users to inject arbitrary web script or HTML via wikitext, as demonstrated by a wikilink to a page named "javascript:alert('XSS!')."
