Prior to 3.8.6, the pre-installation web/instalador/instalador.php endpoint is reachable before config.php exists and processes unauthenticated installation POST data. In the Linux reinstall flow, a crafted usuario value reaches a command executed by shell_exec(). The installer also writes attacker-controlled values into executable config.php and concatenates the database name nomebd into a CREATE DATABASE statement. Successful exploitation can execute commands as the web-server user, persist attacker-controlled PHP configuration, and alter or disrupt the application and its data. This issue is fixed in version 3.8.6.","state":0,"publishedAt":"2026-10-14T19:44:02.494+00:00","modifiedAt":"2026-10-20T02:06:11.939+00:00","affected":[{"ecosystem":"Vendor product","name":"WeGIA","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"LabRedesCefetRJ\",\n                    \"product\": \"WeGIA\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.8.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:L","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-wm6j-4rfm-399q","https://github.com/LabRedesCefetRJ/WeGIA/issues/96","https://github.com/LabRedesCefetRJ/WeGIA/pull/1705","https://github.com/LabRedesCefetRJ/WeGIA/commit/b13c4b0b416d99a8145f583e0893bc8172155469","https://github.com/LabRedesCefetRJ/WeGIA/releases/tag/3.8.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55679","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55679","identifiers":["CVE-2026-55679"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
