UBUNTU-CVE-2026-56703

Adminer before 5.4.3 contains a remote code execution vulnerability in SQLite query handling where VACUUM INTO is not blocked despite ATTACH restrictions. Authenticated attackers can execute VACUUM INTO to write PHP code to arbitrary file paths and execute commands on the server...

CVE-2026-56702

Adminer versions before 5.4.3 contain an unrestricted file upload vulnerability in the AdminerFileUpload plugin that allows authenticated users to upload PHP files by exploiting a permissive default extension allowlist. Attackers can upload PHP webshells to columns ending in path and execute...

UBUNTU-CVE-2026-34964

Adminer before 5.5.0 contains a server-side request forgery vulnerability in the login form's server field validator, which only inspects leading integers for privileged ports and fails to reject non-numeric port values. Attackers can inject PDO DSN keys like host= and port= into the server...

UBUNTU-CVE-2026-34968

Adminer before 5.4.3 contains an arbitrary file deletion vulnerability in SQLite mode where the database-list drop action fails to validate file extensions before deletion. An authenticated attacker can submit arbitrary relative file paths in the db parameter to delete any files writable by the P...

CVE-2026-56704

Adminer before 5.4.3 inserts unsanitized database server version strings into script tags with valid CSP nonces without proper validation. Attackers controlling a rogue MySQL server can return crafted version strings that break out of the JavaScript context and execute arbitrary code, bypassing...

UBUNTU-CVE-2026-34967

Adminer versions 5.3.0 through 5.4.2 with the sql-log plugin enabled contain an arbitrary file write vulnerability in the ns parameter of plugins/sql-log.php. An authenticated user can supply path traversal sequences in the ns parameter to write arbitrary .sql files with attacker-controlled conte...

UBUNTU-CVE-2026-56702

Adminer versions before 5.4.3 contain an unrestricted file upload vulnerability in the AdminerFileUpload plugin that allows authenticated users to upload PHP files by exploiting a permissive default extension allowlist. Attackers can upload PHP webshells to columns ending in path and execute...

UBUNTU-CVE-2026-34959

Adminer 4.6.0 before 5.5.0 prepends the client-supplied X-Forwarded-Prefix header to $SERVER"REQUESTURI" with no trusted-proxy check and no validation of the prefix value. An attacker can supply an absolute URL e.g. X-Forwarded-Prefix: https://evil.example that flows into Location redirect header...

Adminer before 5.4.3 contains an arbitrary file deletion vulnerability in SQLite mode where the database-list drop action fails to validate file extensions before deletion. An authenticated attacker can submit arbitrary relative file paths in the db parameter to delete any files writable by the P...

UBUNTU-CVE-2026-56706

Adminer before 5.4.3 uses a CSRF token scheme that transmits both the XOR mask and the masked value in every token format rand XOR secret:rand, allowing anyone who observes a single CSRF token e.g., via network sniffing, log files, Referrer header, or XSS to recover the session secret with a sing...

CVE-2026-56705

Adminer before 5.4.3 fails to sanitize the server field before constructing a PDO DSN string, allowing unauthenticated attackers to inject ODBC parameters via semicolons. Attackers can inject TraceFile and TraceOn parameters to write PHP code to the web root, achieving remote code execution when...

UBUNTU-CVE-2026-16434

Adminer 4.6.0 through 5.5.0 fixed in 5.5.1 contains an incomplete fix for a prior X-Forwarded-Prefix vulnerability GHSA-8478-xrj3-h9c2. The validation guard bootstrap.inc.php only rejects prefixes matching ^/^/, blocking //evil.com but allowing values such as /\evil.com whose second character is ...

An authenticated user can supply path traversal sequences in the ns parameter to write arbitrary .sql files with attacker-controlled conte...

CVE-2026-56706

Adminer before 5.4.3 contains a CSRF token design flaw: each token transmits both the XOR mask and the masked value in the format (rand XOR secret):rand, so a single observed token (via network sniffing, log files, Referrer header, or XSS) lets an attacker recover the session secret with one XOR ...

CVE-2026-56706 Adminer before 5.4.3 CSRF Token Secret Recovery via XOR Masking
