Shaarli is a personal bookmarking service. Versions prior to 0.16.3 are vulnerable to stored XSS in
application/front/controller/visitor/BookmarkListController.php. Thepermalinkhandler concatenates the raw$bookmark->getTitle()into thepagetitletemplate variable and the RainTPL template emits it into the document<title>element without HTML escaping. A bookmark title containing</title><script>...</script>closes the document title early and the injected script executes in the Shaarli origin for any visitor of/shaare/{hash}. Shaarli's metadata fetcher copies a remote page's<title>text verbatim into the local bookmark title, so an attacker who hosts an attacker-controlled URL and convinces an administrator to bookmark it plants the payload with no further interaction — and the resulting permalink fires for every visitor including the administrator on first save, providing a one-shot administrator account takeover. Version 0.16.3 fixes the issue. - References
