How to Fix CVE-2025-12764

To remediate this vulnerability, upgrade all affected Pgadmin4 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

pgadmin4 fixed: 9.10 
pip install pgadmin4>=9.10
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show pgadmin4

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-12764, inspect your installed packages using pip:

pip show pgadmin4

Analyze the terminal output to locate any version of Pgadmin4 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.10), your application is affected.

Note: The pip show pgadmin4 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-90: Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection'), where the product constructs all or part of an ldap query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended ldap query when it is sent to a downstream component. In Pgadmin4, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

pgAdmin <= 9.9 is affected by an LDAP injection vulnerability in the LDAP authentication flow that allows an attacker to inject special LDAP characters in the username, causing the DC/LDAP server and the client to process an unusual amount of data DOS.
