Versions 8.0.0-BETA3 prior to 8.3.1 contain a vulnerability due to insecure deserialization of cookie data. If exploited, since SDKs process cookie content without prior authentication, a threat actor could send a specially crafted cookie containing malicious serialized data. Applications using the Auth0-PHP SDK are affected, as are applications using the Auth0/symfony, Auth0/laravel-auth0, or Auth0/wordpress SDKs, because those SDKsrely on the Auth0-PHP SDK versions from 8.0.0-BETA3 until 8.14.0. Version 8.3.1 contains a patch for the issue.","published_at":"2025-06-03T20:52:35.064000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":9.3,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:H/SI:H/SA:H","cvss_v4_severity":"CRITICAL","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-502"],"nvd_references":["https://github.com/auth0/auth0-PHP/security/advisories/GHSA-v9m8-9xxp-q492","https://github.com/auth0/laravel-auth0/security/advisories/GHSA-c42h-56wx-h85q","https://github.com/auth0/symfony/security/advisories/GHSA-98j6-67v3-mw34","https://github.com/auth0/wordpress/security/advisories/GHSA-862m-5253-832r","https://github.com/auth0/auth0-PHP/commit/04b1f5daa8bdfebc5e740ec5ca0fb2df1648a715"],"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":"2026-06-28T23:27:16.555994Z"},"effective_severity":"CRITICAL","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":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"H","value_label":"High"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"H","value_label":"High"},{"metric":"SA","name":"Availability (Subsequent System)","value":"H","value_label":"High"}]},"affected":[{"vendor_slug":"auth0","vendor_name":"auth0","product_slug":"auth0-php","product_name":"auth0-PHP","version_start":">= 8.0.0-BETA3, < 8.3.1","version_start_inclusive":true,"version_end":">= 8.0.0-BETA3, < 8.3.1","version_end_inclusive":true,"cpe23_uri":"cve5:auth0:auth0-php:>= 8.0.0-BETA3, < 8.3.1:>= 8.0.0-BETA3, < 8.3.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/auth0/auth0-PHP/security/advisories/GHSA-v9m8-9xxp-q492","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/auth0/laravel-auth0/security/advisories/GHSA-c42h-56wx-h85q","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/auth0/symfony/security/advisories/GHSA-98j6-67v3-mw34","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/auth0/wordpress/security/advisories/GHSA-862m-5253-832r","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/auth0/auth0-PHP/commit/04b1f5daa8bdfebc5e740ec5ca0fb2df1648a715","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-06-03T20:52:35.064000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:46:59.738979Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:46:59.738979Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:46:59.738979Z","label":"CVSS score revised","source":"cvelistv5"}]}
