{"apiVersion":"1.0","identifier":"CVE-2026-81529","description":"Improper neutralization of delimiters in connection-URL construction allows connection-option injection in the MongoDB C# Driver. When an application passes untrusted text into the driver-s connection-URL builder and round-trips the builder back into a client configuration, the untrusted text is serialized without neutralizing the URL/option delimiters and is then re-parsed as authoritative connection options. A low-privileged user of such an application can thereby introduce or suppress security-relevant connection settings.","publishedAt":"2026-08-27T20:18:51","lastModifiedAt":"2026-08-28T00:18:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81529","cvssScore":7.1,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N","epssProbability":0.00174,"riskScore":0.72,"affectedProduct":"MongoDB C# Driver","affectedVersions":"unknown","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81529","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81529","en":"https://www.redsauce.net/en/cves/CVE-2026-81529","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81529","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81529","de":"https://www.redsauce.net/de/cves/CVE-2026-81529","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81529","el":"https://www.redsauce.net/el/cves/CVE-2026-81529"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81529"}}
