{"id":"CVE-2026-45068","aliases":["GHSA-xx3c-qf5g-hc39"],"url":"https://o3.security/vulnerability/CVE-2026-45068","summary":"Symfony: Argument Injection in SendmailTransport via Dash-Prefixed Recipient Address","details":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, SendmailTransport in -t mode appended recipient addresses to the sendmail command line without a -- end-of-options separator, allowing an address beginning with - to be interpreted as a sendmail command-line option instead of an address. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.","published":"2026-07-14T19:02:10.265Z","modified":"2026-08-12T03:51:13.851880678Z","cvss":null,"epss":{"score":0.00524,"percentile":0.4208,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/mailer","fixedVersion":"5.4.52"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"5.4.52"},{"ecosystem":"Packagist","name":"symfony/mailer","fixedVersion":"6.4.40"},{"ecosystem":"Packagist","name":"symfony/mailer","fixedVersion":"7.4.12"},{"ecosystem":"Packagist","name":"symfony/mailer","fixedVersion":"8.0.12"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"6.4.40"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"7.4.12"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"8.0.12"}],"fix":{"url":"https://github.com/symfony/symfony/commit/c45144862dc289d03952f41f6078174089a3afc6","label":"symfony/symfony@c451448"},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v5.4.52"},{"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/2026/45xxx/CVE-2026-45068.json"},{"type":"ADVISORY","url":"https://github.com/symfony/symfony/security/advisories/GHSA-xx3c-qf5g-hc39"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45068"},{"type":"FIX","url":"https://github.com/symfony/symfony/commit/c45144862dc289d03952f41f6078174089a3afc6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.851880678Z"}}
