Prior to 16.4.0, check_upgrade_access_rights() in admin/include/functions_upgrade.php conditionally escapes the submitted username only when the removed get_magic_quotes_gpc function exists, so PHP 8 and later concatenate an unauthenticated username directly into the upgrade authentication SQL query. When database upgrades are pending, a crafted query result can satisfy the status and password checks, set PHPWG_IN_UPGRADE, and authorize upgrade execution without valid administrator credentials. This can cause unauthorized database integrity changes and service disruption. This vulnerability is fixed in 16.4.0."}],"source":{"advisory":"GHSA-6wj3-7fhw-gfpm","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/Piwigo/Piwigo/security/advisories/GHSA-6wj3-7fhw-gfpm","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-25T16:40:38.942377Z","id":"CVE-2026-44642","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-25T16:41:02.238Z"}}]}}
