{"apiVersion":"1.0","identifier":"CVE-2026-81095","description":"pg-aiguide started its MCP HTTP transport without enabling the host allow-list the underlying SDK provides. src/httpServer.ts called the shared httpServerFactory helper and never set the DNS-rebinding-protection option, so the transport accepted a request whatever host it named. A page in a browser could therefore point a name it controlled at the address the server was bound to and drive the locally reachable MCP server through the visitor-s browser. The protection was already available in the packaged transport and simply not turned on, so updating the dependency alone would not have closed it. Version 0.5.1 passes the option explicitly.","publishedAt":"2026-08-27T17:20:51","lastModifiedAt":"2026-08-27T17:20:51","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81095","cvssScore":6.8,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","epssProbability":0.0016,"riskScore":0.69,"affectedProduct":"pg-aiguide","affectedVersions":"<0.5.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81095","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81095","en":"https://www.redsauce.net/en/cves/CVE-2026-81095","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81095","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81095","de":"https://www.redsauce.net/de/cves/CVE-2026-81095","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81095","el":"https://www.redsauce.net/el/cves/CVE-2026-81095"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81095"}}
