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.","published_at":"2026-02-12T19:16:06.618000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":8.9,"cvss_v4_vector":"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","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-180"],"nvd_references":["https://github.com/php/frankenphp/security/advisories/GHSA-g966-83w7-6w38","https://github.com/php/frankenphp/commit/04fdc0c1e8fde94e2c1ad86217e962c88d27c53e","https://github.com/php/frankenphp/releases/tag/v1.11.2"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:22.440317Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"},{"metric":"E","name":"E","value":"P","value_label":"Physical"}]},"affected":[{"vendor_slug":"php","vendor_name":"php","product_slug":"frankenphp","product_name":"frankenphp","version_start":"< 1.11.2","version_start_inclusive":true,"version_end":"< 1.11.2","version_end_inclusive":true,"cpe23_uri":"cve5:php:frankenphp:< 1.11.2:< 1.11.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/php/frankenphp/security/advisories/GHSA-g966-83w7-6w38","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/php/frankenphp/commit/04fdc0c1e8fde94e2c1ad86217e962c88d27c53e","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/php/frankenphp/releases/tag/v1.11.2","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-12T19:16:06.618000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:51:59.897730Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:51:59.897730Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:51:59.897730Z","label":"CVSS score revised","source":"cvelistv5"}]}
