In affected versions output data of the function wp_die() can be leaked under certain conditions, which can include data like nonces. It can then be used to perform actions on your behalf. This has been patched in WordPress 5.8.1, along with any older affected versions via minor releases. It's strongly recommended that you keep auto-updates enabled to receive the fix.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["https://github.com/WordPress/wordpress-develop/security/advisories/GHSA-m9hc-7v5q-x8q5","https://hackerone.com/reports/1142140","https://www.debian.org/security/2021/dsa-4985","https://github.com/WordPress/wordpress-develop/security/advisories/GHSA-m9hc-7v5q-x8q5","https://hackerone.com/reports/1142140"],"products":["debian:debian_linux","wordpress:wordpress"],"source":"nvd","synced_at":"2026-10-19T21:23:41.316049955+00:00"},"epss":{"cve":"CVE-2021-39200","score":0.01968,"percentile":0.80384,"date":"2026-11-01"},"kev":null,"osv":[],"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).
