Custom MyCode (BBCode) for the visual editor (_SCEditor_) doesn't escape input properly when rendering HTML, resulting in a DOM-based XSS vulnerability. This weakness can be exploited by pointing a victim to a page where the visual editor is active (e.g. as a post or Private Message) and operates on a maliciously crafted MyCode message. This may occur on pages where message content is pre-filled using a GET/POST parameter, or on reply pages where a previously saved malicious message is quoted. The impact is be mitigated when: 1. the visual editor is disabled globally (_Admin CP ? Configuration ? Settings ? Clickable Smilies and BB Code: [Clickable MyCode Editor](https://github.com/mybb/mybb/blob/mybb_1836/install/resources/settings.xml#L2087-L2094)_ is set to _Off_), or 2. the visual editor is disabled for individual user accounts (_User CP ? Your Profile ? Edit Options_: _Show the MyCode formatting options on the posting pages_ checkbox is not checked). MyBB 1.8.37 resolves this issue with the commit `6dcaf0b4d`. Users are advised to upgrade. Users unable to upgrade may mitigate the impact without upgrading MyBB by changing the following setting (_Admin CP ? Configuration ? Settings_):- _Clickable Smilies and BB Code ? [Clickable MyCode Editor](https://github.com/mybb/mybb/blob/mybb_1836/install/resources/settings.xml#L2087-L2094)_: _Off_. Similarly, individual MyBB forum users are able to disable the visual editor by diabling the account option (_User CP ? Your Profile ? Edit Options_) _Show the MyCode formatting options on the posting pages_.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/73623", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, {"timestamp": "2023-11-06T20:28:49Z", "date_only": false, "value": "2023-11-06T20:28:49.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "Telegram/vrYhd9EGO9YMgYE7p-1wX1LQ0PsHTFM-ZHccSrg8msBuxQ", "record": "CVE-2023-46251", "field": "creation_timestamp", "uuid": "185c48a0-1975-4fa3-a146-26cbc6720ff5", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, {"timestamp": "2023-11-07T03:38:07Z", "date_only": false, "value": "2023-11-07T03:38:07.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "Telegram/nvHcaD1k09ioCsXkfpvyYRjz9w6NVZp19bu9X1G4nCv6Eg", "record": "CVE-2023-46251", "field": "creation_timestamp", "uuid": "b25e25af-103e-4a49-9d91-6f23d17a1d66", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, {"timestamp": "2023-11-10T11:11:22Z", "date_only": false, "value": "2023-11-10T11:11:22.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "https://t.me/crackcodes/4605", "record": "CVE-2023-46251", "field": "creation_timestamp", "uuid": "624ee616-7a89-4677-b5ae-e0e7c8522f3c", "content": "https://system32.ink/mybb-cve-2023-46251-stored-dom-xss/", "url": "https://t.me/crackcodes/4605", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, {"timestamp": "2023-12-13T01:20:52.969Z", "date_only": false, "value": "2023-12-13T01:20:52.969775Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-46251", "record": "GSD-2023-46251", "field": "gsd.osvSchema.modified", "linked_record": true}, {"timestamp": "2024-02-29T01:41:21.943Z", "date_only": false, "value": "2024-02-29T01:41:21.943", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-46251", "record": "GSD-2023-46251", "field": "namespaces.nvd.nist.gov.cve.lastModified", "linked_record": true}, {"timestamp": "2024-08-02T20:37:40.233Z", "date_only": false, "value": "2024-08-02T20:37:40.233Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "cve-2023-46251", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-09-04T19:26:53.568Z", "date_only": false, "value": "2024-09-04T19:26:53.568111Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "cve-2023-46251", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2024-09-04T19:26:53.568Z", "date_only": false, "value": "2024-09-04T19:26:53.568111Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-46251", "record": "FKIE_CVE-2023-46251", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2024-09-04T19:32:41.984Z", "date_only": false, "value": "2024-09-04T19:32:41.984Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "cve-2023-46251", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-09-04T19:32:41.984Z", "date_only": false, "value": "2024-09-04T19:32:41.984Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "cve-2023-46251", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T06:30:31.310Z", "date_only": false, "value": "2026-06-17T06:30:31.310", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-46251", "record": "FKIE_CVE-2023-46251", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-11T22:48:31.475Z", "anchors": {"origin": {"timestamp": "2023-11-06T17:41:30.378Z", "date_only": false, "value": "2023-11-06T17:41:30.378Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "cve-2023-46251", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2023-11-06T17:41:30.378Z", "date_only": false, "value": "2023-11-06T17:41:30.378Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "cve-2023-46251", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": {"timestamp": "2023-11-06T20:09:30Z", "date_only": false, "value": "2023-11-06T20:09:30.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "https://t.me/proxy_bar/1814", "record": "CVE-2023-46251", "field": "creation_timestamp", "uuid": "24aec9d6-d157-4a88-998a-f272290cb700", "content": "CVE-2023-46251 -
