Prior to 6.13.9, 7.8.9, 8.22.1, and 9.1.6, a vulnerability allows bypassing Mongoose’s sanitizeFilter query sanitization mechanism via the $nor operator. When sanitizeFilter is enabled, Mongoose wraps query operators in $eq to neutralize them. However, prior to the fix, $nor was not included in the set of logical operators that are recursively sanitized. Because $nor accepts an array (like $and and $or), and arrays do not trigger hasDollarKeys(), malicious operators such as $ne, $gt, or $regex could be injected inside a $nor clause without being sanitized. This vulnerability is fixed in 6.13.9, 7.8.9, 8.22.1, and 9.1.6."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"Automattic","product":"mongoose","versions":[{"version":"< 6.13.9","status":"affected"},{"version":">= 7.0.0, <= 7.8.8","status":"affected"},{"version":">= 8.0.0, <= 8.22.0","status":"affected"},{"version":">= 9.0.0, <= 9.1.5","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-05-14T18:17:58.426797Z","id":"CVE-2026-42334","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-74"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:mongoosejs:mongoose:*:*:*:*:*:node.js:*:*","versionEndExcluding":"6.13.9","matchCriteriaId":"CBB0B526-FA31-4FBF-B978-BFF89CD1C4F8"},{"vulnerable":true,"criteria":"cpe:2.3:a:mongoosejs:mongoose:*:*:*:*:*:node.js:*:*","versionStartIncluding":"7.0.0","versionEndExcluding":"7.8.9","matchCriteriaId":"3B4DE619-C57D-47BF-8C59-7426C057D9E5"},{"vulnerable":true,"criteria":"cpe:2.3:a:mongoosejs:mongoose:*:*:*:*:*:node.js:*:*","versionStartIncluding":"8.0.0","versionEndExcluding":"8.22.1","matchCriteriaId":"CFC38AA7-F763-4259-B609-07C374E94A10"},{"vulnerable":true,"criteria":"cpe:2.3:a:mongoosejs:mongoose:*:*:*:*:*:node.js:*:*","versionStartIncluding":"9.0.0","versionEndExcluding":"9.1.6","matchCriteriaId":"A849EB68-502F-4B87-B7D9-5021F2F17D5C"}]}]}],"references":[{"url":"https://github.com/Automattic/mongoose/security/advisories/GHSA-wpg9-53fq-2r8h","source":"security-advisories@github.com","tags":["Mitigation","Vendor Advisory"]}]}
