DokuWiki before 2026-07-14c PHP Object Injection via Draft Race Condition

DokuWiki before 2026-07-14c contains a PHP object injection vulnerability in Draft::getDraftText() that passes draft file contents to unserialize() without restricting allowed classes. Authenticated users with edit rights can race concurrent draft rewrites to splice serialized data, instantiating gadgets like MemoryIndex or Installer for arbitrary file write, deletion, and code execution.

DokuWiki: DokuWiki: Unauthorized account creation via registration function

An issue in DokuWiki 2025-05-14b "Librarian" 56.2 allows a remote attacker to create an account via the register function in inc/auth.php. NOTE: this is disputed by the Supplier because this is the intentional behavior when the product is configured for self-registration (a non-default feature). The supplier also notes that there is no configuration migration scenario that would result in the self-registration being enabled without the administrators knowledge.

inc/init.php in DokuWiki 2009-02-14, rc2009-02-06, and rc2009-01-30, when register_globals is enabled, allows remote attackers to include and execute arbitrary local files via the config_cascade[main][default][] parameter to doku.php. NOTE: PHP remote file inclusion is also possible in PHP 5 using ftp:// URLs.

Cross Site Scripting vulnerability in DokuWiki 2025-05-14a 'Librarian'[56.1] allows a remote attacker to execute arbitrary code via the q parameter

An arbitrary file upload vulnerability in the Media Manager component of DokuWiki 2024-02-06a allows attackers to execute arbitrary code by uploading a crafted SVG file. NOTE: as noted in the 4267 issue reference, there is a position that exploitability can only occur with a misconfiguration of the product.

Remote Denial of Service via Media Upload in Dokuwiki 2025-05-14b

An issue in Dokuwiki v.2025-05-14b "Librarian" [56.2] allows a remote attacker to cause a denial of service via the media_upload_xhr() function in the media.php file

Dokuwiki 2018-04-22b - Username Enumeration

DokuWiki 2018-04-22b contains a username enumeration vulnerability in its password reset functionality that allows attackers to identify valid user accounts. Attackers can submit different usernames to the password reset endpoint and distinguish between existing and non-existing accounts by analyzing the server's error response messages.

DokuWiki through 2017-02-19c has stored XSS when rendering a malicious RSS or Atom feed, in /inc/parser/xhtml.php. An attacker can create or edit a wiki that uses RSS or Atom data from an attacker-controlled server to trigger JavaScript execution. The JavaScript can be in an author field, as demonstrated by the dc:creator element.

DokuWiki through 2017-02-19b has XSS in the at parameter (aka the DATE_AT variable) to doku.php.

DokuWiki through 2017-02-19c has stored XSS when rendering a malicious language name in a code element, in /inc/parser/xhtml.php. An attacker can create or edit a wiki with this element to trigger JavaScript execution.

DokuWiki 2014-05-05a and earlier, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a user name and password starting with a null (\0) character, which triggers an anonymous bind.

The default file type whitelist configuration in conf/mime.conf in the Media Manager in DokuWiki before 2014-09-29b allows remote attackers to execute arbitrary web script or HTML by uploading an SWF file, then accessing it via the media parameter to lib/exe/fetch.php.

DokuWiki before 2014-05-05d and before 2014-09-29c does not properly check permissions for the ACL plugins, which allows remote authenticated users to gain privileges and add or delete ACL rules via a request to the XMLRPC API.

The sendRequest method in HTTPClient Class in file /inc/HTTPClient.php in DokuWiki 2016-06-26a and older, when media file fetching is enabled, has no way to restrict access to private networks. This allows users to scan ports of internal networks via SSRF, such as 10.0.0.1/8, 172.16.0.0/12, and 192.168.0.0/16.

DokuWiki 2016-06-26a and older uses $_SERVER[HTTP_HOST] instead of the baseurl setting as part of the password-reset URL. This can lead to phishing attacks. (A remote unauthenticated attacker can change the URL's hostname via the HTTP Host header.) The vulnerability can be triggered only if the Host header is not part of the web server routing process (e.g., if several domains are served by the same web server).

The ajax_mediadiff function in DokuWiki before 2014-05-05a allows remote attackers to access arbitrary images via a crafted namespace in the ns parameter.

inc/template.php in DokuWiki before 2014-05-05a only checks for access to the root namespace, which allows remote attackers to access arbitrary images via a media file details ajax call.

DokuWiki before 2014-05-05b, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a password starting with a null (\0) character and a valid user name, which triggers an unauthenticated bind.

dokuwiki: multiple vulnerabilities in ACL manager

Directory traversal vulnerability in the ACL Manager plugin (plugins/acl/ajax.php) in DokuWiki before 2009-12-25b allows remote attackers to list the contents of arbitrary directories via a .. (dot dot) in the ns parameter.

Cross-site scripting (XSS) vulnerability in the RSS embedding feature in DokuWiki before 2011-05-25a Rincewind allows remote attackers to inject arbitrary web script or HTML via a link.
