Prior to version 0.3.5, in the Mermaid chart rendering component, there is a risky operation of directly using `innerHTML` to set user content. Therefore, any malicious content rendered via Mermaid will directly trigger the exploit chain, leading to command execution. This vulnerability is primarily caused by a failure to fully address the existing XSS issue in the project, leading to another exploit chain. The exploit chain is consistent with the report GHSA-hqr4-4gfc-5p2j, executing arbitrary JavaScript code via XSS and arbitrary commands via exposed IPC. Version 0.3.5 contains an updated fix.","severity":{"version":"3.1","score":9.7,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","level":"critical","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00599,"percentile":0.48941,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79","CWE-94"],"published":"2025-09-09T20:19:52Z","modified":"2026-10-28T02:30:30Z","products":[{"vendor":"thinkinai","product":"deepchat"},{"vendor":"thinkinaixyz","product":"deepchat"}],"references":[{"url":"https://github.com/ThinkInAIXYZ/deepchat/security/advisories/GHSA-f7q5-vc93-wp6j","tags":["x_refsource_CONFIRM","Exploit","Vendor Advisory","advisory"]},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/58xxx/CVE-2025-58768.json","tags":["advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2025-58768","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2025-58768","title":"DeepChat's Mermaid rendering has XSS leading to RCE","description":"DeepChat is a smart assistant uses artificial intelligence.
