Starting in version 12.0.0 and prior to version 2025.4.1, due to an oversight in the validation performed in `UrlPreviewService` and `MkUrlPreview`, it is possible for an attacker to inject arbitrary CSS into the `MkUrlPreview` component. `UrlPreviewService.wrap` falls back to returning the original URL if it's using a protocol that is likely to not be understood by Misskey, IE something other than `http` or `https`. This both can de-anonymize users and_allow further attacks in the client. Additionally, `MkUrlPreview` doesn't escape CSS when applying a `background-image` property, allowing an attacker to craft a URL that applies arbitrary styles to the preview element. Theoretically, an attacker can craft a CSS injection payload to create a fake error message that can deceive the user into giving away their credentials or similar sensitive information. Version 2025.4.1 contains a patch for the issue. \nSeverity: 7.2 | HIGH \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"05 May 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "url": "https://t.me/cvedetector/24485"}, {"timestamp": "2025-05-06T03:23:35Z", "date_only": false, "value": "2025-05-06T03:23:35.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "Telegram/bFFhDRsz5jITaIYyr2g-Li8Bq5utseX25ZdPNGHsnlhVzGo", "record": "CVE-2025-46340", "field": "creation_timestamp", "uuid": "52ec2cd2-521d-4cdc-9735-899a579a366e"}, {"timestamp": "2026-06-17T09:26:15.943Z", "date_only": false, "value": "2026-06-17T09:26:15.943", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2025-46340", "record": "FKIE_CVE-2025-46340", "field": "lastModified"}]}
