{"id":"UBUNTU-CVE-2026-119429","details":"phpMyAdmin through 5.2.3 contains a missing re-authentication vulnerability that allows authenticated attackers to remove two-factor authentication by posting the 2fa key to /config/set. Attackers holding a hijacked session can submit key=2fa with a null JSON value to SetConfigController, stripping 2FA so later logins require only the MySQL password.","modified":"2026-11-04T03:30:32.668449505Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-119429"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119429"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119429"},{"type":"REPORT","url":"https://abraxaslabs.tech/research/phpmyadmin-config-set-2fa"},{"type":"REPORT","url":"https://github.com/phpmyadmin/phpmyadmin"},{"type":"REPORT","url":"https://github.com/phpmyadmin/phpmyadmin/blob/RELEASE_5_2_3/libraries/classes/Controllers/Config/SetConfigController.php#L29-L41"},{"type":"REPORT","url":"https://github.com/phpmyadmin/phpmyadmin/commit/6482dfa28bd56d515f482b008b194a516646fe1b"},{"type":"REPORT","url":"https://github.com/phpmyadmin/phpmyadmin/commit/b2a3e41f1e9ce42d1ee3f07a91f476029987799f"},{"type":"REPORT","url":"https://github.com/phpmyadmin/phpmyadmin/pull/19087"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/phpmyadmin-through-5.2.3-two-factor-authentication-removal-via-config-set"}],"affected":[{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:4.0.6-1","4:4.0.8-1","4:4.0.9-1","4:4.0.10-1","4:4.0.10-1ubuntu0.1","4:4.0.10-1ubuntu0.1+esm1","4:4.0.10-1ubuntu0.1+esm2","4:4.0.10-1ubuntu0.1+esm3","4:4.0.10-1ubuntu0.1+esm4"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4:4.0.10-1ubuntu0.1+esm4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119429.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:4.4.13.1-1","4:4.5.0.2-2","4:4.5.1-1","4:4.5.1-2","4:4.5.1-3","4:4.5.2-1","4:4.5.2-2","4:4.5.3.1-1","4:4.5.4-1","4:4.5.4.1-2","4:4.5.4.1-2ubuntu1","4:4.5.4.1-2ubuntu2","4:4.5.4.1-2ubuntu2.1","4:4.5.4.1-2ubuntu2.1+esm2","4:4.5.4.1-2ubuntu2.1+esm3","4:4.5.4.1-2ubuntu2.1+esm4","4:4.5.4.1-2ubuntu2.1+esm5","4:4.5.4.1-2ubuntu2.1+esm6"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4:4.5.4.1-2ubuntu2.1+esm6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119429.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:4.6.6-5","4:4.6.6-5ubuntu0.2+esm1","4:4.6.6-5ubuntu0.2+esm2","4:4.6.6-5ubuntu0.5","4:4.6.6-5ubuntu0.5+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4:4.6.6-5ubuntu0.5+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119429.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:4.9.1+dfsg1-2","4:4.9.2+dfsg1-1","4:4.9.5+dfsg1-1ubuntu1","4:4.9.5+dfsg1-2","4:4.9.5+dfsg1-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4:4.9.5+dfsg1-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119429.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:5.0.4+dfsg2-2ubuntu5","4:5.1.1+dfsg1-5ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4:5.1.1+dfsg1-5ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119429.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:5.2.1+dfsg-1ubuntu1","4:5.2.1+dfsg-2ubuntu1","4:5.2.1+dfsg-2ubuntu2","4:5.2.1+dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4:5.2.1+dfsg-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119429.json"}},{"package":{"name":"phpmyadmin","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/phpmyadmin?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4:5.2.3+dfsg-1","4:5.2.4~dev~git20260809.e0909b211b+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"phpmyadmin","binary_version":"4
