Prior to versions 8.6.69 and 9.7.0-alpha.14, an authenticated user can bypass the immutability guard on session fields (expiresAt, createdWith) by sending a null value in a PUT request to the session update endpoint. This allows nullifying the session expiry, making the session valid indefinitely and bypassing configured session length policies. This issue has been patched in versions 8.6.69 and 9.7.0-alpha.14.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-697"],"references":["https://github.com/parse-community/parse-server/commit/90802969fc713b7bc9733d7255c7519a6ed75d21","https://github.com/parse-community/parse-server/commit/ebccd7fe2708007e62f705ee1c820a6766178777","https://github.com/parse-community/parse-server/pull/10347","https://github.com/parse-community/parse-server/pull/10348","https://github.com/parse-community/parse-server/security/advisories/GHSA-f6j3-w9v3-cq22"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34574","score":0.00218,"percentile":0.12282,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-f6j3-w9v3-cq22","url":"https://osv.dev/vulnerability/GHSA-f6j3-w9v3-cq22","summary":"Parse Server has a session field immutability bypass via falsy-value guard","modified":"2026-04-06T15:27:15.966361294Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0 <9.7.0-alpha.14"],"fixed":["9.7.0-alpha.14"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.69"],"fixed":["8.6.69"]}]}],"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).
