This stored XSS payload is executed whenever another admin views the firewall rules page, enabling session hijacking, unauthorized actions within the interface, or further internal pivoting. Exploitation requires only high-privilege GUI access, and the complexity of the attack is low.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/4rdr/proofs/blob/main/info/IPFire-2.29-Stored-XSS-via-Firewall.md","https://github.com/4rdr/proofs/blob/main/info/IPFire-2.29-Stored-XSS-via-Firewall.md"],"products":["ipfire:ipfire"],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-50975","score":0.00283,"percentile":0.2083,"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).
