{"apiVersion":"1.0","identifier":"CVE-2026-81522","description":"A weakness in the MongoDB C++ Driver-s handling of caller-supplied namespace identifiers allows special characters embedded in those identifiers. An application that builds a namespace identifier from untrusted input without validating it may therefore have its operation directed at a different target than intended. This can result in limited unauthorized read and write access to data belonging to another logical tenant of the affected application.","publishedAt":"2026-08-27T20:18:50","lastModifiedAt":"2026-08-28T00:18:20","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81522","cvssScore":8.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00265,"riskScore":0.83,"affectedProduct":"MongoDB C++ Driver","affectedVersions":"unknown","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81522","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81522","en":"https://www.redsauce.net/en/cves/CVE-2026-81522","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81522","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81522","de":"https://www.redsauce.net/de/cves/CVE-2026-81522","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81522","el":"https://www.redsauce.net/el/cves/CVE-2026-81522"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81522"}}
