Overview
python-ldap is a Python modules for implementing LDAP clients
Affected versions of this package are vulnerable to Improper Validation of Specified Type of Input via the escape_filter_chars function. An attacker can bypass input sanitization and potentially manipulate or disclose LDAP data by supplying crafted list or dict objects as the assertion_value parameter when the escape_mode is set to 1.
Note: This is only exploitable if the application uses the non-default escape_mode=1 configuration and passes untrusted list or dict objects to the function.
