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.","categories":["Unclassified"],"product":"Piwigo","vendor":"Piwigo","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-44642","source_modified_at":"2026-09-25T16:41:02.238Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Piwigo","vendor":"Piwigo","versions":[{"version":"< 16.4.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.01285,"percentile":0.69918,"score_date":"2026-10-23"},"published_at":"2026-09-25T15:47:59.389Z","modified_at":"2026-09-25T16:41:02.238Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-44642","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T16:41:02.238Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-44642","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Piwigo/Piwigo/security/advisories/GHSA-6wj3-7fhw-gfpm","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/Piwigo/Piwigo/commit/1ff9d04534feb5f8f3cc2d3613c0fe8b51a1c0ba","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Piwigo/Piwigo/commit/2cfa7a3d194c8b95edde43038d8f5be5a359e785","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Piwigo/Piwigo/releases/tag/16.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-09-25T16:40:38.942377Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T16:41:02.238Z","content_hash":"c3b09106c9e3adda4ca3c97873235444c83d88f438585048309636875c7ab233"}}
