{"cve":"CVE-2026-32886","nvd":{"published":"2026-03-18T22:16:25.663","modified":"2026-06-17T10:36:30.647","status":"Analyzed","description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.24 and 8.6.47, remote clients can crash the Parse Server process by calling a cloud function endpoint with a crafted function name that traverses the JavaScript prototype chain of a registered cloud function handler, causing a stack overflow. The fix in versions 9.6.0-alpha.24 and 8.6.47 restricts property lookups during cloud function name resolution to own properties only, preventing prototype chain traversal from stored function handlers. There is no known workaround.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-1321"],"references":["https://github.com/parse-community/parse-server/pull/10210","https://github.com/parse-community/parse-server/pull/10211","https://github.com/parse-community/parse-server/security/advisories/GHSA-4263-jgmp-7pf4"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32886","score":0.00525,"percentile":0.44512,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4263-jgmp-7pf4","url":"https://osv.dev/vulnerability/GHSA-4263-jgmp-7pf4","summary":"Parse Server's Cloud function dispatch crashes server via prototype chain traversal","modified":"2026-03-20T12:26:16.149865Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0 <9.6.0-alpha.24"],"fixed":["9.6.0-alpha.24"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.47"],"fixed":["8.6.47"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
