CVE-2026-62237: Inefficient Regular Expression Complexity in getgrav gravCVE-2026-62237 0 Grav CMS versions prior to 2.0.4 contain a regular expression denial of service (ReDoS) vulnerability in the regex_replace filter and function used within Twig content processing. This vulnerability can be triggered when Twig processing in page content is enabled, allowing an authenticated page editor to supply a crafted regular expression that causes excessive CPU usage and denial of service. The vulnerability arises from catastrophic backtracking in PHP's preg_replace() function. The default setting disables Twig processing, reducing exposure unless explicitly enabled.
