{"id":"CVE-2026-47212","summary":"Symfony: Twilio Notifier Webhook Parser Never Verifies the X-Twilio-Signature HMAC: Unauthenticated Webhook Event Injection","details":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 6.4.40, 7.4.12, and 8.0.12, TwilioRequestParser::doParse() received the configured webhook secret but ignored the X-Twilio-Signature HMAC header, allowing unauthenticated POST requests to inject forged Twilio status payloads. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.","aliases":["GHSA-55rj-x2vc-4whq"],"modified":"2026-07-17T03:45:42.128124638Z","published":"2026-07-14T19:00:30.703Z","database_specific":{"cwe_ids":["CWE-306","CWE-347"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47212.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v6.4.40"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v7.4.12"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v8.0.12"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47212.json"},{"type":"ADVISORY","url":"https://github.com/symfony/symfony/security/advisories/GHSA-55rj-x2vc-4whq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47212"},{"type":"FIX","url":"https://github.com/symfony/symfony/commit/8545fb2af6c07dfb5ef0fc8d9bccf86db2c94356"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/symfony/security-http","events":[{"introduced":"1b49ad8e9f2c3ceec011d67ac09e774e4107416b"},{"fixed":"816860d96c4fb7ffd7708ae0531ea6e5a1190773"},{"introduced":"f84d7d3c93e6a884908402775199b1f7d55c7be1"},{"fixed":"1fc7ca636cbd2cad29b42cc13c9fd0c681c6efee"},{"introduced":"bea6dc79db4d95c34b77ec27273d812aa64d65be"},{"fixed":"d776945b2dc41c0e609c56c1ef69863ab56856ed"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:sensiolabs:symfony:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"6.4.0"},{"fixed":"6.4.40"},{"introduced":"7.0.0"},{"fixed":"7.4.12"},{"introduced":"8.0.0"},{"fixed":"8.0.12"}]}},{"type":"GIT","repo":"https://github.com/symfony/symfony","events":[{"introduced":"228a275ddcc1a4301fc8865945c0686b56658135"},{"fixed":"95a951788e30c45356278f4e4472cbbf552d0eb9"},{"introduced":"d78c5f403d7ee794993660b1d5155536edd36fc1"},{"fixed":"275f5cbccbcc50205206f05e599c4f57009aadb8"},{"introduced":"2e913a829cfbbf9cb38b321bdff1806b44b192eb"},{"fixed":"06d3b2c9a8aeb5d8493738cc51e24f6a1215827c"},{"fixed":"8545fb2af6c07dfb5ef0fc8d9bccf86db2c94356"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:sensiolabs:symfony:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"6.4.0"},{"fixed":"6.4.40"},{"introduced":"7.0.0"},{"fixed":"7.4.12"},{"introduced":"8.0.0"},{"fixed":"8.0.12"}]}}],"versions":["v6.4.39","v8.0.11","v7.4.11","v7.4.0-BETA1","v8.0.9","v7.4.9","v6.4.34","v8.0.8","v7.4.8","v8.0.6","v7.4.6","v6.4.31","v8.0.4","v7.4.4","v8.0.3","v7.4.3","v8.0.1","v7.4.1","v6.4.30","v7.4.0","v8.0.0","v7.4.0-RC2","v7.4.0-RC1","v6.4.26","v6.4.25","v6.4.24","v6.4.23","v7.3.0","v6.4.22","v7.3.0-RC1","v7.3.0-BETA2","v7.3.0-BETA1","v6.4.21","v6.4.19","v6.4.18","v7.2.1","v6.4.15","v7.2.0-RC1","v7.2.0","v7.2.0-BETA2","v6.4.14","v7.2.0-BETA1","v6.4.13","v6.4.12","v6.4.11","v6.4.9","v6.4.8","v7.1.0-RC1","v7.1.0","v7.1.0-BETA1","v6.4.7","v6.4.4","v6.4.3","v7.0.1","v6.4.0-RC2","v6.4.0","v7.0.0-RC2","v7.0.0","v6.4.38","v8.0.10","v6.4.37","v6.4.36","v8.0.7","v6.4.35","v8.0.5","v6.4.33","v6.4.32","v8.0.2","v6.4.29","v6.4.28","v6.4.27","v6.4.20","v6.4.17","v6.4.16","v6.4.10","v6.4.6","v6.4.5","v6.4.2","v6.4.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47212.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
