In the shipped\nproduction configuration, the Controller trusts the client-supplied X-Forwarded-For header as\nthe request's client IP without verifying that it originated from a trusted proxy, and selects\nthe leftmost (attacker-controlled) header value. As a result, an attacker can forge the source\nIP address recorded for their requests in the Controller's audit and access logs, degrading\nthe integrity of forensic and SIEM attribution. The flaw does not grant additional access.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-348"],"references":["https://access.redhat.com/errata/RHSA-2026:71113","https://access.redhat.com/errata/RHSA-2026:71114","https://access.redhat.com/errata/RHSA-2026:71177","https://access.redhat.com/errata/RHSA-2026:71179","https://access.redhat.com/security/cve/CVE-2026-84718"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-84718","score":0.00136,"percentile":0.03006,"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).
