CVE-2012-1582 1 Mediawiki 1 Mediawiki 2026-06-16 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in the wikitext parser in MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 allows remote attackers to inject arbitrary web script or HTML via a crafted page with "forged strip item markers," as demonstrated using the CharInsert extension.
CVE-2012-1581 1 Mediawiki 1 Mediawiki 2026-06-16 5.0 MEDIUM N/A
MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 uses weak random numbers for password reset tokens, which makes it easier for remote attackers to change the passwords of arbitrary users.
CVE-2012-1580 1 Mediawiki 1 Mediawiki 2026-06-16 6.8 MEDIUM N/A
Cross-site request forgery (CSRF) vulnerability in Special:Upload in MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 allows remote attackers to hijack the authentication of unspecified victims for requests that upload files.
CVE-2012-1579 1 Mediawiki 1 Mediawiki 2026-06-16 5.0 MEDIUM N/A
The resource loader in MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 includes private data such as CSRF tokens in a JavaScript file, which allows remote attackers to obtain sensitive information.
CVE-2012-1578 1 Mediawiki 1 Mediawiki 2026-06-16 6.8 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 allow remote attackers to hijack the authentication of users with the block permission for requests that (1) block a user via a request to the Block module or (2) unblock a user via a request to the Unblock module.

includes/User.php in MediaWiki before 1.16.5, when wgBlockDisablesLogin is enabled, does not clear certain cached data after verification of an auth token fails, which allows remote attackers to bypass authentication by creating crafted wikiUserID and wikiUserName cookies, or by leveraging an unattended workstation.
CVE-2011-1765 2 Mediawiki, Microsoft 2 Mediawiki, Internet Explorer 2026-06-16 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.5, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .shtml at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1578 and CVE-2011-1587.
