What is CVE-2026-7816?

CVE-2026-7816 is a high-severity command injection vulnerability in pgadmin.org pgAdmin 4, published on 11 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

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.

Weakness: CWE-78
