By adding a PHP shell with a filename starting with a dot \".\", this can bypass extension control implemented in the plugin. Moreover, there is a race condition in the zip extraction process which makes the shell file live long enough on the filesystem to be callable by an attacker.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-306"],"references":["http://packetstormsecurity.com/files/167190/WordPress-Tatsu-Builder-Remote-Code-Execution.html","https://darkpills.com/wordpress-tatsu-builder-preauth-rce-cve-2021-25094/","https://wpscan.com/vulnerability/fb0097a0-5d7b-4e5b-97de-aacafa8fffcd","http://packetstormsecurity.com/files/167190/WordPress-Tatsu-Builder-Remote-Code-Execution.html","https://darkpills.com/wordpress-tatsu-builder-preauth-rce-cve-2021-25094/"],"products":["brandexponents:tatsu"],"source":"nvd","synced_at":"2026-10-19T21:30:03.577988018+00:00"},"epss":{"cve":"CVE-2021-25094","score":0.83232,"percentile":0.99679,"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).
