Miraheze: Security Vulnerabilities
ManageWiki is a MediaWiki extension allowing users to manage wikis. Prior to commit 2f177dc, ManageWiki is vulnerable to reflected or stored XSS in the review dialog. A logged-in attacker must change a form field to include a malicious payload. If that same user then opens the "Review Changes" dialog, the payload will be rendered and executed in the context of their own session. This issue has been patched in commit 2f177dc.

ManageWiki is a MediaWiki extension allowing users to manage wikis. Prior to commit 00bebea, when enabling a conflicting extension, a restricted extension would be automatically disabled even if the user did not hold the ManageWiki-restricted right. This issue has been patched in commit 00bebea. A workaround involves ensuring that any extensions requiring specific permissions in `$wgManageWikiExtensions` also require the same permissions for managing any conflicting extensions.

ManageWiki is a MediaWiki extension allowing users to manage wikis. Versions before commit f504ed8, are vulnerable to SQL injection when renaming a namespace in Special:ManageWiki/namespaces when using a page prefix (namespace name, which is the current namespace you are renaming) with an injection payload. This issue has been patched in commit f504ed8. A workaround for this vulnerability involves setting `$wgManageWiki['namespaces'] = false;`.

CreateWiki is an extension used at Miraheze for requesting & creating wikis. The name of requested wikis is not escaped on Special:RequestWikiQueue, so a user can insert arbitrary HTML that is displayed in the request wiki queue when requesting a wiki. If a wiki creator comes across the XSS payload, their user session can be abused to retrieve deleted wiki requests, which typically contains private information. Likewise, this can also be abused on those with the ability to suppress requests to view sensitive information. This issue has been patched with commit `693a220` and all users are advised to apply the patch. Users unable to upgrade should disable Javascript and/or prevent access to the vulnerable page (Special:RequestWikiQueue).

WikiDiscover is an extension designed for use with a CreateWiki managed farm to display wikis. Special:WikiDiscover is a special page that lists all wikis on the wiki farm. However, the special page does not make any effort to escape the wiki name or description. Therefore, if a wiki sets its name and/or description to an XSS payload, the XSS will execute whenever the wiki is shown on Special:WikiDiscover. This issue has been patched with commit `2ce846dd93` and all users are advised to apply that patch. User unable to upgrade should block access to `Special:WikiDiscover`.

CreateWiki is Miraheze's MediaWiki extension for requesting & creating wikis. An oversight during the writing of the patch for CVE-2024-29897 may have exposed suppressed wiki requests to private wikis that added Special:RequestWikiQueue to the read whitelist to users without the `(read)` permission. This vulnerability is fixed in 8f8442ed5299510ea3e58416004b9334134c149c.

CreateWiki is Miraheze's MediaWiki extension for requesting & creating wikis. Suppression of wiki requests does not work as intended, and always restricts visibility to those with the `(createwiki)` user right regardless of the settings one sets on a given wiki request. This may expose information to users who are not supposed to be able to access it.

ManageWiki is a MediaWiki extension allowing users to manage wikis. Special:ManageWiki does not escape escape interface messages on the `columns` and `help` keys on the form descriptor. An attacker may exploit this and would have a cross site scripting attack vector. Exploiting this on-wiki requires the `(editinterface)` right. Users should apply the code changes in commits `886cc6b94`, `2ef0f50880`, and `6942e8b2c` to resolve this vulnerability. There are no known workarounds for this vulnerability.

WikiDiscover is an extension designed for use with a CreateWiki managed farm to display wikis. On Special:WikiDiscover, the `Language::date` function is used when making the human-readable timestamp for inclusion on the wiki_creation column. This function uses interface messages to translate the names of months and days. It uses the `->text()` output mode, returning unescaped interface messages. Since the output is not escaped later, the unescaped interface message is included on the output, resulting in an XSS vulnerability. Exploiting this on-wiki requires the `(editinterface)` right. This vulnerability has been addressed in commit `267e763a0`. Users are advised to update their installations. There are no known workarounds for this vulnerability.
