    Package        : mediawiki     Version        : 1:1.35.13-1+deb11u4     CVE ID         : CVE-2025-3469 CVE-2025-6590 CVE-2025-6591 CVE-2025-6593                      CVE-2025-6594 CVE-2025-6595 CVE-2025-6597 CVE-2025-6926                      CVE-2025-32072 CVE-2025-32696 CVE-2025-32698 CVE-2025-32699

    Multiple security vulnerabilities were found in mediawiki, a website     engine for collaborative work, that could lead to information     disclosure or privilege escalation.

    CVE-2025-3469

        User input was not properly sanitized during web page generation,         which could lead to information disclosure or privilege escalation         via Cross-site Scripting.

    CVE-2025-6590

        User input was not sanitized in the password reset form, which could lead         to information disclosure for private pages via transclusion.

    CVE-2025-6591

        HTML injection in API `action=feedcontributions` output from i18n         messages.

    CVE-2025-6593

        {{SITENAME}} registered email address has been changed email was         sent to unverified email addresses, which could lead to information         disclosure.

    CVE-2025-6594

        XSS in Special:ApiSandbox.  While the known issue is not exploitable         in 1.39, the backported changes provide some security hardening         just in case.

    CVE-2025-6595

        Stored XSS through system messages in MultimediaViewer.

    CVE-2025-6597

        Autocreation was treated as login for the purposes of security         reauthentication.  However it doesn't necessarily involve real-time         user identification, as it can be based on some provider identifying         the user based on a session cookie or similar low-fidelity         information.  An attacker who got hold of a CentralAuth session         cookie (valid on any wiki) could just visit a wiki where the user         has no local account yet, get an account autocreated, and then         change credentials or perform other sensitive operations.

    CVE-2025-6926

        Allow extensions to suppress the reauth flag on login.  This is a         workaround for extensions with some sort of autologin implemented         via the login page to indicate that the login flow didn't involve         the user actually logging in, it merely copied some central login         state, and so isn't appropriate for the reauthentication flag.

    CVE-2025-32072

        HTML injection in feed output from i18n message.

    CVE-2025-32696

         reupload-own restriction could be bypassed by reverting file.

    CVE-2025-32698

        Improper enforcing of suppression restrictions in LogPager.php.

    CVE-2025-32699

        Potential javascript injection attack enabled by Unicode         normalization in Action API.

    For Debian 11 bullseye, these problems have been fixed in version     1:1.35.13-1+deb11u4.
