Prior to 8.6.12 and 9.5.1-alpha.1, the requestKeywordDenylist security control can be bypassed by placing any nested object or array before a prohibited keyword in the request payload. This is caused by a logic bug that stops scanning sibling keys after encountering the first nested value. Any custom requestKeywordDenylist entries configured by the developer are equally by-passable using the same technique. All Parse Server deployments are affected. The requestKeywordDenylist is enabled by default. This vulnerability is fixed in 8.6.12 and 9.5.1-alpha.1. Use a Cloud Code beforeSave trigger to validate incoming data for prohibited keywords across all classes."}],"source":{"advisory":"GHSA-q342-9w2p-57fp","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-30938","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-03-10T16:56:19.410227Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-10T17:01:16.003Z"}}]}}
