The custom Zeus semgrep check app.rules.semgrep.zeus.atr-c0002.credential-to-log-sink.py flagged command_executor.py:109, inside CommandExecutor.run's KEY=VAL token-parsing loop: this line only appends a non-KV argv token to the args list being built for subprocess.run -- it is not a logging call and does not emit any credential. The actual logging call a few lines later (logging.info('Executing command: %s ...', cmd_str, ...)) logs the joined command ARGV (cmd_str), which could include a secret value if a caller passed one as a bare argument (not a KEY=VAL env prefix, which is diverted into exec_env and excluded from cmd_str/args). This is a potential logging-hygiene concern but is CLI tooling for a PR-generation workflow operating on repo/PR identifiers, not attacker-controlled external input, and the KEY=VAL inline env mechanism specifically exists to keep secrets out of the logged command string.","vulnerability_details":null,"fix_guidance":null,"why_this_matters":"Plaintext secrets are easily exfiltrated.","context_note":null,"within_declared_contract":true,"transport_gated":false,"mitigation_present":true,"evidence":[{"path":"tools/caretaker-agent/cloudrun/pr-generator/workflow/command_executor.py","start_line":100,"end_line":114,"snippet":" # Convert string commands into argument tokens, parsing inline KEY=VAL env prefixes\n if isinstance(cmd, str):\n tokens = shlex.split(cmd)\n args: list[str] = []\n for token in tokens:\n if \"=\" in token and not args:\n k, v = token.split(\"=\", 1)\n exec_env[k] = v\n else:\n args.append(token)\n else:\n args = list(cmd)\n\n cmd_str = \" \".join(args)\n logging.info(\"Executing command: %s (CWD: %s)\", cmd_str, active_cwd)"},{"path":"packages/core/src/code_assist/oauth2.ts","start_line":80,"end_line":85,"snippet":"// Note: It's ok to save this in git because this is an installed application\n// as described here: https://developers.google.com/identity/protocols/oauth2#installed\n// \"The process results in a client ID and, in some cases, a client secret,\n// which you embed in the source code of your application.

The custom Zeus semgrep check app.rules.semgrep.zeus.atr-c0002.credential-to-log-sink.py flagged command_executor.py:109, inside CommandExecutor.run's KEY=VAL token-parsing loop: this line only appends a non-KV argv token to the args list being built for subprocess.run -- it is not a logging call and does not emit any credential. The actual logging call a few lines later (logging.info('Executing command: %s ...', cmd_str, ...)) logs the joined command ARGV (cmd_str), which could include a secret value if a caller passed one as a bare argument (not a KEY=VAL env prefix, which is diverted into exec_env and excluded from cmd_str/args). This is a potential logging-hygiene concern but is CLI tooling for a PR-generation workflow operating on repo/PR identifiers, not attacker-controlled external input, and the KEY=VAL inline env mechanism specifically exists to keep secrets out of the logged command string.","vulnerability_details":null,"fix_guidance":null,"why_this_matters":"Plaintext secrets are easily exfiltrated.","context_note":null,"within_declared_contract":true,"transport_gated":false,"mitigation_present":true,"evidence":[{"path":"tools/caretaker-agent/cloudrun/pr-generator/workflow/command_executor.py","start_line":100,"end_line":114,"snippet":" # Convert string commands into argument tokens, parsing inline KEY=VAL env prefixes\n if isinstance(cmd, str):\n tokens = shlex.split(cmd)\n args: list[str] = []\n for token in tokens:\n if \"=\" in token and not args:\n k, v = token.split(\"=\", 1)\n exec_env[k] = v\n else:\n args.append(token)\n else:\n args = list(cmd)\n\n cmd_str = \" \".join(args)\n logging.info(\"Executing command: %s (CWD: %s)\", cmd_str, active_cwd)"},{"path":"packages/core/src/code_assist/oauth2.ts","start_line":80,"end_line":85,"snippet":"// Note: It's ok to save this in git because this is an installed application\n// as described here: https://developers.google.com/identity/protocols/oauth2#installed\n// \"The process results in a client ID and, in some cases, a client secret,\n// which you embed in the source code of your application.
