pgAdmin <= 8.3 is affected by a path-traversal vulnerability while deserializing users’ sessions in the session handling code. If the server is running on Windows, an unauthenticated attacker can load and deserialize remote pickle objects and gain code execution. If the server is running on POSIX/Linux, an authenticated attacker can upload pickle objects, deserialize them, and gain code execution.

pgAdmin <= 8.5 is affected by a multi-factor authentication bypass vulnerability. This vulnerability allows an attacker with knowledge of a legitimate account’s username and password may authenticate to the application and perform sensitive actions within the application, such as managing files and executing SQL queries, regardless of the account’s MFA enrollment status.

pgAdmin versions 8.11 and earlier are vulnerable to a security flaw in OAuth2 authentication. This vulnerability allows an attacker to potentially obtain the client ID and secret, leading to unauthorized access to user data.

pgAdmin <= 8.8 has an installation Directory permission issue. Because of this issue, attackers can gain unauthorised access to the installation directory on the Debian or RHEL 8 platforms.

pgAdmin <= 8.5 is affected by XSS vulnerability in /settings/store API response json payload. This vulnerability allows attackers to execute malicious script at the client end.
