{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/82646?format=json","vulnerability_id":"VCID-rmxq-h4p1-f7h2","summary":"FrankenPHP is a modern application server for PHP. Prior to 1.11.2, FrankenPHP’s CGI path splitting logic improperly handles Unicode characters during case conversion. The logic computes the split index (for finding .php) on a lowercased copy of the request path but applies that byte index to the original path. Because strings.ToLower() in Go can increase the byte length of certain UTF-8 characters (e.g., Ⱥ expands when lowercased), the computed index may not align with the correct position in the original string. This results in an incorrect SCRIPT_NAME and SCRIPT_FILENAME, potentially causing FrankenPHP to execute a file other than the one intended by the URI. This vulnerability is fixed in 1.11.2.","aliases":[{"alias":"CVE-2026-24895"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-24895","reference_id":"","reference_type":"","scores":[{"value":"0.00029","scoring_system":"epss","scoring_elements":"0.08792","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-24895"},{"reference_url":"https://github.com/php/frankenphp/commit/04fdc0c1e8fde94e2c1ad86217e962c88d27c53e","reference_id":"04fdc0c1e8fde94e2c1ad86217e962c88d27c53e","reference_type":"","scores":[{"value":"8.9","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:T/P:M/B:A/M:M/D:T/2026-02-12T20:03:49Z/"}],"url":"https://github.com/php/frankenphp/commit/04fdc0c1e8fde94e2c1ad86217e962c88d27c53e"},{"reference_url":"https://github.com/php/frankenphp/security/advisories/GHSA-g966-83w7-6w38","reference_id":"GHSA-g966-83w7-6w38","reference_type":"","scores":[{"value":"8.9","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:T/P:M/B:A/M:M/D:T/2026-02-12T20:03:49Z/"}],"url":"https://github.com/php/frankenphp/security/advisories/GHSA-g966-83w7-6w38"},{"reference_url":"https://github.com/php/frankenphp/releases/tag/v1.11.2","reference_id":"v1.11.2","reference_type":"","scores":[{"value":"8.9","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:T/P:M/B:A/M:M/D:T/2026-02-12T20:03:49Z/"}],"url":"https://github.com/php/frankenphp/releases/tag/v1.11.2"}],"weaknesses":[{"cwe_id":180,"name":"Incorrect Behavior Order: Validate Before Canonicalize","description":"The product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step."}],"exploits":[],"severity_range_score":"8.9 - 8.9","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-rmxq-h4p1-f7h2"}
