{"schemaVersion":3,"id":"CVE-2026-62672","aliases":[],"status":"published","duplicateOf":null,"title":"Grav: Authenticated ReDoS via regex_replace in Twig Sandbox","description":"Grav is a file-based Web platform. Prior to 2.0.4, Grav allowlists the regex_replace filter and function in system/config/security.yaml, and GravExtension::regexReplace() passes an editor-controlled pattern directly to preg_replace(). When security.twig_content.process_enabled is enabled, an authenticated page editor can publish a catastrophically backtracking pattern that consumes PHP worker CPU and denies service to site visitors. This issue is fixed in version 2.0.4.","dates":{"published":"2026-08-19T15:44:36.287Z","modified":"2026-08-19T18:00:39.622Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":6,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":6,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/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":0.00381,"percentile":0.30941,"severity":"low","asOf":"2026-10-22T00:00:00.000Z","change":{"pp":-0.006000000000000016,"baselineDate":"2026-09-22T00:00:00.000Z","baselineScore":0.00387},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.00381,"percentile":0.30941}],"last30":[{"date":"2026-09-22T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00381,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00381,"percentile":null
