pgAdmin Query Export Command Injection Flaw

OS command injection (CWE-78) vulnerability in pgAdmin 4 Import/Export query export. User-supplied input was interpolated directly into a psql \copy metacommand template without sanitization. An authenticated user could inject ") TO PROGRAM 'cmd'" to break out of the \copy (...) context and achieve arbitrary command execution on the pgAdmin server, or ") TO '/path'" for arbitrary file write. Additional fields (format, on_error, log_verbosity) were also raw-interpolated and exploitable. Fix adds a parens-balance parser modeled on psql's strtokx tokenizer, allow-lists format/on_error/log_verbosity, rejects null bytes in the query, and tightens type and gating checks. This issue affects pgAdmin 4: before 9.15.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

pgAdmin 4 contains a critical OS command injection vulnerability in its Import/Export functionality where user-supplied input is directly interpolated into psql metacommands without sanitization. Authenticated users can inject malicious commands like ") TO PROGRAM 'cmd'" to break out of the \copy context and execute arbitrary commands on the pgAdmin server, or write files to arbitrary locations. This vulnerability affects any organization using pgAdmin 4 for database management, particularly those with untrusted or compromised user accounts, since exploitation requires authentication but provides a direct path to server compromise.

Casky's 301 mapped security skills leverage Claude's extended reasoning to detect the attack patterns associated with this vulnerability across MITRE ATT&CK's Initial Access (TA0001) and Resource Development (TA0043) tactics. Practitioners using Casky would identify detection signals including: (1) suspicious \copy metacommand syntax in pgAdmin logs with embedded PROGRAM or file path directives, (2) unexpected child processes spawned from pgAdmin worker threads, (3) anomalous database export requests containing shell metacharacters or command separators, and (4) file write operations to unusual directories from pgAdmin service accounts. The platform's skill mapping would correlate these indicators with CWE-89 (Improper Neutralization of Special Elements) patterns, enabling security teams to distinguish legitimate query exports from exploitation attempts and respond before arbitrary code execution occurs.
