This is due to the fact that all fields in the \"Naming Conventions\" section do not properly sanitize user input, nor escape it on output. This makes it possible for authenticated attackers, with administrative privileges, to inject JavaScript code into the setting that will execute whenever a user accesses the injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","score":4.8},"cwes":["CWE-79"],"references":["https://github.com/lesterchan/wp-useronline/commit/59c76b20e4e27489f93dee4ef1254d6204e08b3c","https://packetstormsecurity.com/files/168479/wpuseronline2880-xss.txt","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=2770235%40wp-useronline&new=2770235%40wp-useronline&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/5c4fb14c-de6d-4247-8f83-050f1350f6a2?source=cve","https://www.wordfence.com/vulnerability-advisories/#CVE-2022-2941"],"products":["wp-useronline_project:wp-useronline"],"source":"nvd","synced_at":"2026-10-19T21:35:14.992143698+00:00"},"epss":{"cve":"CVE-2022-2941","score":0.0778,"percentile":0.94653,"date":"2026-10-31"},"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).
