{"apiVersion":"1.0","identifier":"CVE-2026-62672","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.","publishedAt":"2026-08-19T16:18:20","lastModifiedAt":"2026-08-19T18:16:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62672","cvssScore":6,"cvssVector":"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","epssProbability":0.00301,"riskScore":0.62,"affectedProduct":"Grav","affectedVersions":"<2.0.4","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62672","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62672","en":"https://www.redsauce.net/en/cves/CVE-2026-62672","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62672","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62672","de":"https://www.redsauce.net/de/cves/CVE-2026-62672","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62672","el":"https://www.redsauce.net/el/cves/CVE-2026-62672"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62672"}}
