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-2016-6331 1 Mediawiki 1 Mediawiki 2026-06-17 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-2015-8628 1 Mediawiki 1 Mediawiki 2026-06-17 4.3 MEDIUM 5.3 MEDIUM
The (1) Special:MyPage, (2) Special:MyTalk, (3) Special:MyContributions, (4) Special:MyUploads, and (5) Special:AllMyUploads pages 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 allow remote attackers to obtain sensitive user login information via crafted links combined with page view statistics.
CVE-2015-8627 1 Mediawiki 1 Mediawiki 2026-06-17 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-2015-8626 1 Mediawiki 1 Mediawiki 2026-06-17 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-2015-8625 1 Mediawiki 1 Mediawiki 2026-06-17 5.0 MEDIUM 7.5 HIGH
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 sanitize parameters when calling the cURL library, which allows remote attackers to read arbitrary files via an @ (at sign) character in unspecified POST array parameters.
CVE-2015-8624 1 Mediawiki 1 Mediawiki 2026-06-17 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 2026-06-17 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-2015-8622 1 Mediawiki 1 Mediawiki 2026-06-17 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!')."
CVE-2015-8009 1 Mediawiki 1 Mediawiki 2026-06-17 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-2015-8008 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2026-06-17 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-2015-8005 1 Mediawiki 1 Mediawiki 2026-06-17 5.0 MEDIUM N/A
MediaWiki before 1.23.11, 1.24.x before 1.24.4, and 1.25.x before 1.25.3 uses the thumbnail ImageMagick command line argument, which allows remote attackers to obtain the installation path by reading the metadata of a PNG thumbnail file.
CVE-2015-8004 1 Mediawiki 1 Mediawiki 2026-06-17 4.0 MEDIUM N/A
MediaWiki before 1.23.11, 1.24.x before 1.24.4, and 1.25.x before 1.25.3 does not properly restrict access to revisions, which allows remote authenticated users with the viewsuppressed user right to remove revision suppressions via a crafted revisiondelete action, which returns a valid a change form.
