Prior to 2.0.0-beta.2, an authenticated user with administrative privileges can achieve Remote Code Execution (RCE) by uploading a specially crafted ZIP file through the \"Direct Install\" tool. While the system attempts to block direct .php file uploads, it fails to inspect the contents of uploaded ZIP archives. Once a malicious plugin is extracted, it can execute arbitrary PHP code or drop a persistent web shell on the server. This vulnerability is fixed in 2.0.0-beta.2.","published_at":"2026-05-11T14:58:42.273000Z","last_modified_at":null,"cvss_v3_score":9.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-94"],"nvd_references":["https://github.com/getgrav/grav/security/advisories/GHSA-w48r-jppp-rcfw","https://github.com/getgrav/grav/commit/5a12f9be8314682c8713e569e330f11805d0a663"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T23:46:59.033383Z"},"effective_severity":"CRITICAL","badges":["exploit"],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"H","value_label":"High"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"getgrav","vendor_name":"getgrav","product_slug":"grav","product_name":"grav","version_start":"< 2.0.0-beta.2","version_start_inclusive":true,"version_end":"< 2.0.0-beta.2","version_end_inclusive":true,"cpe23_uri":"cve5:getgrav:grav:< 2.0.0-beta.2:< 2.0.0-beta.2"}],"exploit_refs":[{"source":"exploit-db","kind":"exploit-db","url":"https://www.exploit-db.com/exploits/52578","title":"Grav CMS 2.0.0-beta.2 -  Remote Code Execution","author":"Mustafa Murat Akgül","disclosed_at":"2026-05-26"}],"news":[],"references":[{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-w48r-jppp-rcfw","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/getgrav/grav/commit/5a12f9be8314682c8713e569e330f11805d0a663","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-05-11T14:58:42.273000Z","label":"CVE published","source":null},{"type":"exploit_known","at":"2026-05-26T00:00:00Z","label":"Public exploit available","source":"exploit-db"},{"type":"cvss_changed","at":"2026-06-28T17:54:12.493575Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:12.493575Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:12.493575Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"}]}
