CVE-2026-79916

MaxKB is an open-source AI assistant for enterprise. Prior to 2.10.5-lts, authenticated workspace members can inject control characters into AWS Bedrock accesskeyid and secretaccesskey fields that updateawscredentials writes to /root/.aws/credentials without safe parsing. An attacker can append a new AWS profile containing credentialprocess, then select that profile during a later model-validation request so botocore executes an attacker-controlled command as root. This vulnerability is fixed in 2.10.5-lts.
