{"schemaVersion":3,"id":"CVE-2026-55794","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Craft CMS is a content management system (CMS). In versions 5.9.0 and above prior to 5.10.0, control panel users with the ability to edit entries can execute unsandboxed Twig code via the HTTP Referrer header, potentially leading to authenticated RCE. The issue happens when a user is saving entries. Strings for a signed redirect URL are being compiled as a Twig template via renderObjectTemplate(), and while a sandboxed alternative already exists (renderSandboxedObjectTemplate()), it is not used in this case. This signed URL can be specified by users, as it is reflected in the “Referer” HTTP request header, which is under attacker control. This issue has been fixed in version 5.10.0.","dates":{"published":"2026-07-01T23:26:22.071Z","modified":"2026-07-02T12:41:39.752Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.7,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00412,"percentile":0.34279,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00412},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00412,"percentile":0.34279}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00412,"percentile":null},{"date":"2026-10-
