Depending on the behavior of those methods, there may be JNDI injection with an attacker-supplied payload located elsewhere in that JSON document. This was exploited in the wild in 2023 through 2025. NOTE: this issue exists because of an incomplete fix for CVE-2017-18349. Also, a later bypass is covered by CVE-2022-25845.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10.0},"cwes":["CWE-829"],"references":["https://cert.360.cn/warning/detail?id=7240aeab581c6dc2c9c5350756079955","https://github.com/alibaba/fastjson/compare/1.2.47...1.2.48","https://github.com/vulhub/vulhub/tree/master/fastjson/1.2.47-rce","https://www.cloudsek.com/blog/androxgh0st-continues-exploitation-operators-compromise-a-us-university-for-hosting-c2-logger","https://www.cnvd.org.cn/flaw/show/CNVD-2019-22238"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-70974","score":0.00746,"percentile":0.54846,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-jm7w-5684-pvh8","url":"https://osv.dev/vulnerability/GHSA-jm7w-5684-pvh8","summary":"FASTJSON Includes Functionality from Untrusted Control Sphere ","modified":"2026-10-05T18:45:05.985873086Z","packages":[{"ecosystem":"Maven","name":"com.alibaba:fastjson","purl":"pkg:maven/com.alibaba/fastjson","ranges":["<1.2.48"],"fixed":["1.2.48"]}]}],"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).
