Technical description

To pass a server's password to psql and to the utilities pgAdmin 4 runs as background processes, the server manager wrote it into pgAdmin's own process environment: as PGPASSWORD for the PSQL tool, and under a per-process variable for a utility. Nothing removed it afterwards. pgAdmin's environment is shared by every user's requests and copied into every process it starts, so in server mode another user's later PSQL session or utility inherited the password, and libpq used PGPASSWORD for any connection made without a password of its own, letting one user connect with another user's saved password. The fix puts the password only into the environment built for the process that needs it and starts psql with a copy of pgAdmin's environment instead of the environment itself. This issue affects pgAdmin 4: before 9.19.

———Insertion of sensitive information into a log file in Amazon Kinesis Producer Library for Java before 1.0.8, when the library's logger is configured at DEBUG log level, might allow local users to obtain the AWS credentials that the library resolved for the application. Separately, affected versions of the library pass these credentials to the native child process as command-line arguments, where a local user can read them from the process argument list. To remediate this issue, users should upgrade to version 1.0.8 or later, rotate any long-term IAM user keys, revoke active role sessions where needed, and restrict or redact log data written by an affected version. 0.x users should migrate to software.amazon.kinesis:amazon-kinesis-producer 1.0.8 or later.8h CVE-2026-921716.5 MED

——7A flaw was found in the Infinispan Operator for Red Hat Data Grid. When cross-site (xsite) TLS is enabled, the operator launches the Gossip Router container with keystore and truststore passwords passed as plain-text command-line arguments (`-tls_keystore_password`, `-tls_truststore_password`). Container args are stored in the Pod spec and visible to any principal with `get pods` permission in the namespace (no `get secrets` required), to node-level processes via `/proc/<pid>/cmdline`, and frequently captured in audit/event logs.4d CVE-2026-1134965.0 MED

——1A flaw was found in cockpit-machines. When saving Virtual Network Computing (VNC) console settings, the configured password is passed directly as a command-line argument to an underlying system utility. A local unprivileged attacker on a host that allows cross-user process inspection could read the exposed password from the process list while another user modifies settings. This credential disclosure can allow unauthorized access to the guest virtual machine's graphical console.20h CVE-2026-1134955.0 MED

4.7%

——1A flaw was found in cockpit-machines. Red Hat Subscription Management (RHSM) authentication tokens are passed as command-line arguments to background helper processes during image retrieval operations. A local, unprivileged attacker on a system permitting cross-user process inspection can view these arguments while the process is active. This flaw can lead to information disclosure, potentially allowing unauthorized access to RHSM resources within the token's validity period.20h CVE-2026-779386.5 MED

——11Letta through 0.16.8 contains an information disclosure vulnerability that allows users running tools to read server secrets because LocalSandbox subprocesses inherit the full server environment. Attackers can run code via POST /v1/tools/run or custom tools to read LETTA_PG_URI, POSTGRES_PASSWORD, and provider API keys, then access cross-tenant database data.10d CVE-2026-1099714.7 MED

——1A flaw was found in the clevis PKCS#11 pin. The clevis-decrypt-pkcs11 script passes the PKCS#11 token PIN as a command-line argument to pkcs11-tool, making it visible to any local user through process listing or the /proc filesystem.20h
