On PostgreSQL or MongoDB replica sets and sharded clusters, other clients' acknowledged writes are rolled back if the batch fails, and PostgreSQL transactions can remain open indefinitely, causing subsequent writes to fail.","categories":["Unclassified"],"product":"parse-server","vendor":"parse-community","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109954","source_modified_at":"2026-10-13T16:43:51.636Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"parse-server","vendor":"parse-community","versions":[{"version":"9.0.0","status":"affected","versionType":"semver","lessThan":"9.10.2-alpha.5"},{"version":"9.10.2-alpha.5","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109954","source_modified_at":"2026-10-13T16:43:51.636Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"parse-server","vendor":"parse-community","versions":[{"version":"5.4.0","status":"affected","versionType":"semver","lessThan":"8.6.96"},{"version":"8.6.96","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109954","source_modified_at":"2026-10-13T16:43:51.636Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"parse-server","ecosystem":null},"version":"9.10.2-alpha.5","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109954","source_modified_at":"2026-10-13T16:43:51.636Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"parse-server","ecosystem":null},"version":"8.6.96","basis":"first unaffected version stated in the CVE record"}],"cvss":8.3,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00218,"percentile":0.11676,"score_date":"2026-10-23"},"published_at":"2026-10-13T13:27:19.012Z","modified_at":"2026-10-13T16:43:51.636Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109954","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T16:43:51.636Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109954","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-jhh9-hrgh-c9gv","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/parse-server-9.0.0-before-9.10.2-alpha.5-transactional-batch-request-write-interference","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T15:47:56.122445Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T16:43:51.636Z","content_hash":"06ea4af793c0a335f19d896c3e2b88054628c6aa8ed0996d88349a72387abb4d"}}
