AdminNeo v5.4.1 gets the latest version from GitHub API in a browser JavaScript function. Version number is then sent by POST request to ?script=version. This endpoint lacks origin validation and accepts POST data from any source. An attacker can POST version[] parameter which PHP converts to an array. On next page load, function rawurlencode() receives this array instead of string and throws TypeError, returning HTTP 500 to all users for …
Adminer blocks ATTACH queries for SQLite to prevent arbitrary file creation. However, VACUUM INTO is not blocked and achieves the same result: writing a database file containing attacker-controlled PHP code to any path with any extension. An authenticated SQLite user can write a web shell to the web root and execute commands. Originally reported in Adminer: GHSA-q4f2-39gr-45jh
AdminNeo's CSRF protection uses a BREACH-resistant XOR masking scheme, but the implementation transmits both the XOR mask and the masked value in every token. This allows any observer who sees a single CSRF token (via network sniffing, log files, Referrer header, or XSS) to instantly recover the session secret and forge unlimited valid CSRF tokens. Additionally, the underlying session token has only ~20 bits of entropy (rand(1, 1e6)), making blind …
AdminNeo inserts the database server's version string into a <script> tag that carries a valid CSP nonce, without any sanitization. A rogue database server can return a crafted version string that breaks out of the JavaScript context and executes arbitrary code. Because the script tag already has a valid nonce, the browser's Content Security Policy does not block execution. No authentication is required when combined with Login CSRF. Originally reported …
This vulnerability is a patch bypass that exploits catastrophic backtracking in a regular expression used to filter ATTACH statements in AdminNeo's SQLite functionality. The original vulnerability (CVE-2021-43008) allowed authenticated users to create PHP files through SQLite ATTACH statements, achieving remote code execution. The patch introduced a regex filter to block ATTACH queries, but this filter is vulnerable to catastrophic backtracking.

AdminNeo allows an authenticated SQLite-mode user to delete arbitrary files writable by the PHP process through the database-list drop action. The SQLite driver validates file extensions when creating or renaming databases, but the database-list drop path passes submitted db[] values directly to unlink().

AdminNeo versions 4.6.0 through at least 5.5.0 are vulnerable to cookie attribute injection via the X-Forwarded-Prefix HTTP header. An attacker who can influence this header (e.g., through a reverse proxy that forwards it from clients, an attacker-controlled upstream proxy, or a man-in-the-middle position) can inject arbitrary cookie attributes including Domain, Path, Secure, and SameSite into all Set-Cookie response headers emitted by AdminNeo. This allows an attacker to expand the cookie …
