CVE-2026-1707
Published: 05 February 2026
Summary
CVE-2026-1707 is a high-severity Improper Access Control (CWE-284) vulnerability in Pgadmin Pgadmin 4. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 8.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and CM-5 (Access Restrictions for Change).
Deeper analysis
CVE-2026-1707 is a restore restriction bypass vulnerability via key disclosure affecting pgAdmin version 9.11 when running in server mode and performing restores from PLAIN-format dump files. The flaw allows attackers to observe active restore operations through the pgAdmin web interface, extract the `\restrict` key in real time, and exploit a race condition by overwriting the restore script with a payload that uses `\unrestrict <key>` to re-enable meta-commands. It has a CVSS v3.1 base score of 7.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L) and is associated with CWE-284 (Improper Access Control).
An attacker with low-privilege access (PR:L) to the pgAdmin web interface can exploit this during an ongoing restore from a PLAIN-format dump. By monitoring the operation, they extract the restriction key and rapidly overwrite the script to bypass restrictions, achieving reliable arbitrary command execution on the pgAdmin host. The network-accessible nature (AV:N) and lack of user interaction (UI:N) requirements, combined with scope change (S:C), enable significant impact including limited confidentiality, integrity, and availability violations.

active restore operation, extract the `\restrict` key in real time, and race the restore process by overwriting the restore script with a payload that re-enables meta-commands using `\unrestrict <key>`. This results in reliable command execution on the pgAdmin host during the restore operation.

Mitigating Controls (NIST 800-53 r5) AI
Enforces access restrictions on pgAdmin restore operations so that an authenticated user cannot extract the \restrict key or inject \unrestrict payloads to bypass command restrictions.
Restricts modification of active restore scripts and files during PLAIN-format restore operations, directly blocking the race-condition overwrite that enables command execution.
Validates restore input (dump contents and meta-commands) to reject or sanitize \unrestrict attempts that re-enable dangerous commands on the pgAdmin host.
