Attackers can manipulate the redir parameter to point to alterar_senha.php, routing through verificarSenhaConfig() instead of verificarSenha() to bypass current password verification and convert temporary session access into permanent account takeover.","state":0,"publishedAt":"2026-08-20T13:46:24.202+00:00","modifiedAt":"2026-10-01T15:21:09.037+00:00","affected":[{"ecosystem":"Vendor product","name":"WeGIA","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"vendor\": \"LabRedesCefetRJ\",\n                    \"product\": \"WeGIA\",\n                    \"packageURL\": \"pkg:github/LabRedesCefetRJ/WeGIA\",\n                    \"repo\": \"https://github.com/LabRedesCefetRJ/WeGIA\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.9.2\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1,"severity":"HIGH"}],"references":["https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-gfcx-7973-hjmp","https://github.com/LabRedesCefetRJ/WeGIA/releases#release-3.9.2","https://www.vulncheck.com/advisories/wegia-authorization-bypass-password-change-via-alterarsenha"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76633","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76633","identifiers":["CVE-2026-76633"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
