Attackers can create bookmarks pointing to loopback, private, or cloud metadata addresses and trigger ThumbnailsController::ajaxUpdate or saving to send blind GET requests, with open_shaarli exposing this to any visitor.","cvssScore":2.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/shaarli/Shaarli","tags":[]},{"url":"https://github.com/shaarli/Shaarli/blob/bfeadb4e5856702c05279bb2a5c405f2ed802015/application/Thumbnailer.php#L82-L98","tags":[]},{"url":"https://github.com/shaarli/Shaarli/blob/bfeadb4e5856702c05279bb2a5c405f2ed802015/application/front/controller/admin/ThumbnailsController.php#L46-L64","tags":[]},{"url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/shaarli-open-mode-thumbnail-fetch-ssrf","tags":[]},{"url":"https://www.vulncheck.com/advisories/shaarli-through-0.16.9-ssrf-via-thumbnail-retrieval-update-thumbnail-route","tags":[]}],"exploitRefs":[{"url":"https://github.com/shaarli/Shaarli","tags":[]},{"url":"https://github.com/shaarli/Shaarli/blob/bfeadb4e5856702c05279bb2a5c405f2ed802015/application/Thumbnailer.php#L82-L98","tags":[]},{"url":"https://github.com/shaarli/Shaarli/blob/bfeadb4e5856702c05279bb2a5c405f2ed802015/application/front/controller/admin/ThumbnailsController.php#L46-L64","tags":[]}],"hasPoc":true,"ai":null}
