Prior to versions 8.6.70 and 9.7.0-alpha.18, an authenticated user with find class-level permission can bypass the protectedFields class-level permission setting on LiveQuery subscriptions. By sending a subscription with a $or, $and, or $nor operator value as a plain object with numeric keys and a length property (an \"array-like\" object) instead of an array, the protected-field guard is bypassed. The subscription event firing acts as a binary oracle, allowing the attacker to infer whether a protected field matches a given test value. This issue has been patched in versions 8.6.70 and 9.7.0-alpha.18."}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","baseScore":4.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":1.4}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-843"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*","versionEndExcluding":"8.6.70","matchCriteriaId":"832B033D-003F-489D-BAAD-D12E1804586D"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*","versionStartIncluding":"9.0.0","versionEndExcluding":"9.7.0","matchCriteriaId":"E3DFF698-B3EE-4DCA-BAF3-9BE52F0F77D7"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha1:*:*:*:node.js:*:*","matchCriteriaId":"3A140D3A-AECC-4CA1-958C-3CA53E313B27"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha10:*:*:*:node.js:*:*","matchCriteriaId":"80D441B8-3B25-40E5-82E2-71E2A5E2F58F"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha11:*:*:*:node.js:*:*","matchCriteriaId":"3CDAE590-5625-4B7C-9B52-23A6725F1B92"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha12:*:*:*:node.js:*:*","matchCriteriaId":"BB2DF38D-26A3-4AB7-8FD3-E9A83995A3BB"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha13:*:*:*:node.js:*:*","matchCriteriaId":"8EFBDB24-8B3B-48E9-9332-C283F9C314F3"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha14:*:*:*:node.js:*:*","matchCriteriaId":"DEB97B07-FB76-4DF6-B068-C88963E27E21"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha15:*:*:*:node.js:*:*","matchCriteriaId":"268C8423-0DA1-4C87-95D9-CF0D32504E89"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha2:*:*:*:node.js:*:*","matchCriteriaId":"BEDAEFBC-DA77-4998-BDD6-A139E15E5CC3"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha3:*:*:*:node.js:*:*","matchCriteriaId":"8C9E59AF-3B82-4D61-847B-A18E7DDF7A34"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha4:*:*:*:node.js:*:*","matchCriteriaId":"2AB743CC-D168-4313-A5AA-43CF76D178E0"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha5:*:*:*:node.js:*:*","matchCriteriaId":"C351C736-AB91-4985-A0B4-43B120F5E5C5"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha6:*:*:*:node.js:*:*","matchCriteriaId":"F02797C9-E67D-4BF4-BB56-8D6DA9178322"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha7:*:*:*:node.js:*:*","matchCriteriaId":"B059E381-D0F6-4425-92C0-167486379A98"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha8:*:*:*:node.js:*:*","matchCriteriaId":"98C19734-3607-467D-9677-10A1909A8D8D"},{"vulnerable":true,"criteria":"cpe:2.3:a:parseplatform:parse-server:9.7.0:alpha9:*:*:*:node.js:*:*","matchCriteriaId":"F55001C0-EDDA-45D9-ABA4-CFF0489C9C01"}]}]}],"references":[{"url":"https://github.com/parse-community/parse-server/commit/f63fd1a
