Prior to 0.8.28, Markdown Preview Enhanced preview-link handling passes a decoded, Markdown-controlled link target to a Windows file-opening helper that invokes child_process.exec with the start command. When a Windows user opens an untrusted Markdown file and clicks a crafted external or unsupported-scheme link, shell metacharacters in the decoded target are interpreted by cmd.exe as command separators, allowing an attacker-selected command to run with the privileges of the current VS Code user. The attack requires one normal preview-link click but does not require malicious workspace configuration, script execution to be enabled, or additional files. This issue is fixed in version 0.8.28.\nhttps://www.cve.org/CVERecord?id=CVE-2026-54525https://github.com/shd101wyy/vscode-markdown-preview-enhanced/security/advisories/GHSA-7v6f-3vq6-r373https://github.com/shd101wyy/crossnote/pull/442https://github.com/shd101wyy/vscode-markdown-preview-enhanced/pull/2318https://github.com/shd101wyy/crossnote/commit/5588ca2121c3da43fe331575dc5cf4ef347b91eehttps://github.com/shd101wyy/vscode-markdown-preview-enhanced/commit/dcd80281c986293b93d9f1af34ced64dcb230c77https://github.com/shd101wyy/crossnote/releases/tag/0.9.29https://github.com/shd101wyy/vscode-markdown-preview-enhanced/releases/tag/0.8.28#shd101wyy #vscode-markdown-preview-enhanced#CVE_2026_54525#bot", "url": "https://infosec.exchange/users/cve/statuses/117442006555805194"}, {"timestamp": "2026-10-15T13:53:20.006Z", "date_only": false, "value": "2026-10-15T13:53:20.006714Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-54525", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-15T13:53:20.006Z", "date_only": false, "value": "2026-10-15T13:53:20.006714Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-54525", "record": "FKIE_CVE-2026-54525", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-10-15T15:05:57.227Z", "date_only": false, "value": "2026-10-15T15:05:57.227Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-54525", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-15T15:05:57.227Z", "date_only": false, "value": "2026-10-15T15:05:57.227Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-54525", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-16T16:00:33.533Z", "date_only": false, "value": "2026-10-16T16:00:33.533", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-54525", "record": "FKIE_CVE-2026-54525", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-12T03:16:59.426Z", "anchors": {"origin": {"timestamp": "2026-10-14T19:06:59.440Z", "date_only": false, "value": "2026-10-14T19:06:59.440Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-54525", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-14T19:06:59.440Z", "date_only": false, "value": "2026-10-14T19:06:59.440Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-54525", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 2448599.986083, "hours": 680.1666628008334, "days": 28.34027761670139, "min_seconds": 2448599.986083, "max_seconds": 2448599.986083, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-14T19:06:59.440Z", "date_only": false, "value": "2026-10-14T19:06:59.440Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-54525", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-12T03:16:59.426Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
