    -------------------------------------------------------------------------     Debian LTS Advisory DLA-4428-1                debian-lts@lists.debian.org     https://www.debian.org/lts/security/                       Guilhem Moulin     December 30, 2025                             https://wiki.debian.org/LTS

    Package        : mediawiki     Version        : 1:1.35.13-1+deb11u6     CVE ID         : CVE-2025-67475 CVE-2025-67478 CVE-2025-67479 CVE-2025-67480                      CVE-2025-67481 CVE-2025-67482 CVE-2025-67484

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

    CVE-2025-67475

        Square brackets in autocomment links were not always escaped.

    CVE-2025-67478

        Commas not separating values in RFC 2822 style headers were not         escaped, hence could be interpreted downstream as value separators.

    CVE-2025-67479

        Underscore and wide underscore were not always sanitized in `data-*`         attribute names.

    CVE-2025-67480

        ApiQueryRevisionsBase did not check for read permissions for the         target page.

    CVE-2025-67481

        Insufficient `style` attribute sanitation in client-side messages         (jqueryMsg).

        As such attributes are difficult to sanitize properly (the logic         needs to be updated constantly as new CSS features are developed by         browser vendors) and their use cases in client-side messages are         extremely rare, they are no longer allowed.

        If needed, `class` and `id` are still allowed, so these elements can         be targeted by normal stylesheets.

    CVE-2025-67482

        Scribunto extension: Segfault in unpack() with large integers         affecting some builds of Lua.

    CVE-2025-67484

        Cross-site scripting (XSS) vulnerability via xslt option for users         with the editinterface permission.  The xslt option is now         disabled by default.  If the former unsafe behavior is desired, is         can be re-enabled by setting `$wgEnableUnsafeXsltOption` to true.

    For Debian 11 bullseye, these problems have been fixed in version     1:1.35.13-1+deb11u6.

    We recommend that you upgrade your mediawiki packages.
