Security Vulnerabilities
phpMyAdmin through 5.2.3 contains an authentication bypass vulnerability in CustomServer::parseAndValidateAssertionResponse() that never verifies WebAuthn assertion signatures against stored public keys. Attackers holding a victim's MySQL credentials can POST a crafted webauthn_request_response with matching challenge, origin, and rpIdHash to bypass the second factor and gain database privileges.

phpMyAdmin through 5.2.3 contains an sql injection vulnerability that allows authenticated users to inject SQL by supplying unescaped col_extra and col_attribute values to /database/central-columns. Attackers can inject SQL into pma__central_columns INSERT and UPDATE queries run with controluser privileges, reading or modifying other users' configuration-storage data.

phpMyAdmin through 5.2.3 contains a stored cross-site scripting vulnerability that allows database users with CREATE privilege to inject script via unescaped table names in DesignerHistory.display(). Attackers can create a table whose name contains HTML markup that executes in another user's session when they add a condition on it in Designer query mode.

phpMyAdmin through 5.2.3 contains a server-side request forgery vulnerability that allows unauthenticated attackers to trigger outbound connections via setup/validate.php, which lacks the setup-disabled guard. Attackers can POST attacker-chosen host and port values reaching Validator::testDBConnection() to open MySQL-protocol connections and probe internal ports using returned error messages.

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.

phpMyAdmin through 5.2.3 contains a cross-site request forgery vulnerability that allows remote attackers to execute arbitrary SQL by bypassing CSRF token checks on non-AJAX POST requests. Attackers can lure authenticated victims into submitting cross-site POSTs carrying sql_query to /sql or /database/sql, running SQL with the victim's database privileges under http or config authentication.

phpMyAdmin through 5.2.3 contains an sql injection vulnerability in Designer saveSetting() that allows authenticated users to inject SQL via unescaped json_encode() output. Attackers can send crafted index or value parameters with operation=save_setting_value to /database/designer to overwrite other users' designer settings or run controluser subqueries.

SQLite before 3.54.0 built with FTS5 contains a heap buffer overflow in fts5MergeRowidLists() that undersizes the output buffer when merging detail=none prefix doclists. Attackers who can populate a detail=none FTS5 table with negative rowids and run a prefix MATCH query can write past the allocation, corrupting heap memory and crashing the process.

SQLite before 3.54.0 built with FTS5 contains a heap buffer overflow in fts5DoSecureDelete() that allows attackers to write past the leaf page buffer via crafted footer key offsets. Attackers can supply a database file with a corrupted FTS5 index that, when deleted from with secure-delete enabled, corrupts heap memory and crashes the application.

SQLite before 3.54.0 contains an information disclosure vulnerability that allows attackers to read uninitialized page-cache memory by supplying a WAL file with an undersized page size. Attackers can craft a database and WAL file whose oversized record payload makes queries like substr() return stale bytes, disclosing other table rows and internal pointers.
