CVE-2025-45406Network attack vector

Disputed stored XSS via debugbar metadata

Published Jul 25, 2025 · Updated Jul 29, 2025

Stored XSS in CodeIgniter4 4.6.0 was reported to let remote attackers execute scripts through debugbar_time metadata. The report claimed that debugbar_time influenced a Debug Toolbar storage filename, but the supplier states that users cannot control the value and Parser output is automatically escaped. GitHub withdrew the advisory as invalid after the reporter accepted the supplier's code-level explanation, leaving no confirmed impact or reachable attack path.
