Subject: [PATCH 05/25] fix: bump cryptography to 46.0.5 and expand CI security
 coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Bump cryptography 44.0.1 → 46.0.5 (CVE-2026-26007)
- Bump Markdown 3.4.4 → 3.8.1 (CVE-2025-69534)
- Add Python 3.13 to quality and security CI matrices
- Add bandit static analysis to security workflow and tox
- Run security checks on pull_request events (not just push)
- Fix SonarQube condition: only run on push or non-fork pull_request
- Remove untrusted fork code execution from sonar_fork_pr job
- Prevent duplicate CI runs via pull_request_target
- Fix stale bot messages and align bandit args with pre-commit

Subject: [PATCH 08/25] Add architecture field to agent deployment commands
 (#3260)

* Add architecture field to agent deployment cmds

* fix: add architecture field to AgentConfigUpdateSchema; add happy-path test

- architecture field was missing from AgentConfigUpdateSchema, causing
  API requests with architecture to fail marshmallow validation
- adds test asserting architecture value is stored in agents config

Subject: [PATCH 09/25] hash passwords and API keys in main config (#3257)

* hash passwords and API keys in main config

* style fixes

* remove superfluous line

* move hash checks to utility function

* simplify code

* add unit tests for config util

* fix: guard _is_hashed against non-string config values

* test: verify make_secure_config logs plaintext once then returns hashes

* style: remove unused logging import from test_config_util.py (F401)

* fix: guard verify_hash against None inputs; use yaml.safe_dump for config overwrite

- verify_hash() now returns False for non-string inputs instead of raising TypeError
  (prevents 500 errors when API key header is absent and None is passed to verify)
- base_world.py overwrite now uses yaml.safe_dump for safe, consistent output
- test: rename 'hash' variable to 'hash_val' to avoid shadowing built-in
- test: add None-input assertions to test_verify_hash
- test: use side_effect=deepcopy to prevent SENSITIVE_CONF module-level mutation

Subject: [PATCH 10/25] fix: replace create_subprocess_shell  (#3265)

* fix: replace create_subprocess_shell with safe exec in start_vue_dev_server

Avoid shell injection risk by using create_subprocess_exec instead.

* fix: address Copilot review feedback on subprocess PR

- Capture proc from create_subprocess_exec, log PID, schedule proc.wait()
  to avoid zombie processes on Vue dev server exit
- Rewrite test to use pytest style, ast-based function extraction,
  and Path-relative server.py resolution

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* test: guard against None return from ast.get_source_segment

ast.get_source_segment() returns None when source offsets are
unavailable; assert it is not None before using it in string checks.

* fix: remove untracked create_task in start_vue_dev_server to avoid zombie subprocess

* test: accept FunctionDef and AsyncFunctionDef in start_vue_dev_server check

* test: use explicit utf-8 encoding in read_text()

---------

Subject: [PATCH 11/25] fix: replace deprecated asyncio.get_event_loop() with
 new_event_loop() (#3266)

* fix: replace deprecated asyncio.get_event_loop() with new_event_loop()

Use asyncio.new_event_loop() in run_tasks() and --fresh block.

* fix: close event loop in finally block; use try/finally in fresh block; fix tests to use ast+pytest

* fix: remove unused variable in asyncio test (flake8 F841)

* test: rewrite asyncio event loop tests to use pure AST inspection

- Replace brittle substring matching with AST Call node inspection
  via a shared _is_asyncio_call() helper
- Remove incorrect startswith('#') guard (AST never includes comments)
- Eliminate ast.get_source_segment() to avoid potential None return

* fix: ensure event loop is always closed and cleared on all exit paths

* fix: cancel pending tasks before closing event loop in run_tasks

* test: relax event loop assertion to allow non-new_event_loop refactors

* test: use explicit utf-8 encoding in read_text()

Subject: [PATCH 12/25] fix: reduce global client_max_size and add configurable
 setting (#3268)

* fix: reduce global client_max_size and add configurable setting

Reduce default from ~26MB to 1MB with configurable client_max_size_mb key.

* fix: add separate upload size limit for authenticated API routes

Global client_max_size stays at 1MB for unauthenticated surfaces.
Introduces api_upload_max_size_mb (default 100MB) applied to the
/api/v2 sub-app, which is entirely behind authentication, allowing
large payload uploads and exfil files without exposing the DoS vector
to unauthenticated routes.

* fix: restore default plugins list and remove mcp

Restores atomic, compass, fieldmanual, and response which were
accidentally dropped. Removes automation and mcp which should not
be in the default plugin set.

* fix: coerce client_max_size config to int; remove unused rate_limit config; test actual runtime behavior

* fix: flake8 style fixes

* test: rewrite client_max_size tests to call real make_app with mock services

Replace the patched duplicate of make_app with calls to the real function
using MagicMock services. The last two constant-comparison tests now also
assert against the actual configured app value.

* test: fix misleading variable name and add root/subapp limit integration test

* style: remove unused patch import in test_client_max_size.py

* test: actually mount v2 as subapp in root_app to validate real runtime behavior

Subject: [PATCH 13/25] fix: degrade gracefully when magma plugin dist is
 absent (#3275)

* fix: degrade gracefully when plugins/magma/dist is absent (#3227)

Previously, AppService.load_plugins() unconditionally appended
'plugins/magma/dist' to the jinja2 template search path. When the
Magma plugin's built assets are absent (e.g. cloned without
--recursive, or --build not yet run), any request reaching
RestApi.landing() or handle_catch() would raise a TemplateNotFound
exception instead of starting cleanly.

- Guard the 'plugins/magma/dist' template-path append behind an
  os.path.exists() check; emit a WARNING log when the path is missing
  so the operator knows the web UI will be unavailable.
- Apply the same guard in tests/conftest.py so the test suite can run
  without a built Magma dist.
- Add tests/services/test_magma_graceful_degradation.py with four
  tests that verify: no crash on load_plugins, no /assets static route
  registered, dist excluded from templates when absent, and included
  when present.

* style: remove unused pytest import in test_magma_graceful_degradation.py

* test: create event loop before RestApi.__init__ to avoid RuntimeError on Python 3.11+

Subject: [PATCH 14/25] fix: guard against None agent in operations summary
 endpoint (#3181) (#3276)

* fix: guard against missing/None agent in operations summary endpoint (#3181)

`get_agents()` and `get_hosts()` in OperationApiManager would raise
KeyError when a link had a falsy paw, and AttributeError when
`find_object()` returned None for an agent that no longer exists in RAM
(e.g. after deletion). Both conditions caused the /operations/summary
endpoint to return HTTP 500.

Fix: skip links with no paw; guard `find_object()` return value with an
explicit None check before calling `.display`.

Adds regression tests for the summary endpoint.

* style: fix E127 continuation line indentation in test_operations_api.py

* test: inject null-paw link into operation to exercise issue #3181 fix

Subject: [PATCH 15/25] fix: resolve trait-only relationship facts from source
 fact list on operation init (#3278)

* fix: resolve trait-only relationship facts from source fact list on operation init

When a fact source defines relationships where the source/target facts
reference only a trait (no value) -- as happens when relationships are
created via the Caldera UI -- _init_source() was seeding those
relationships into the knowledge service with null fact values. This
made the relationships functionally useless because they could never
match any real seeded facts during planning.

The fix introduces Operation._resolve_fact(), which replaces a
trait-only fact stub with the first matching fact (by trait) found in
the source's fact list before the relationship is added to the knowledge
service.  If the fact already carries a value, or no match exists, the
original fact is returned unchanged.

Fixes #2988.

* fix: remove always-truthy if r.target guard; Relationship.target is never None

Subject: [PATCH 16/25] fix: prevent operation report from returning null when
 link paw absent (#3048) (#3279)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: prevent operation report from returning null when a link paw is absent (#3048)

Three related KeyErrors in c_operation.py could cause Operation.report()
to silently return None, which the API then serialised as JSON null and
the UI rendered as "Null":

1. `agents_steps[step.paw]` in report() raised KeyError when a link's
   paw was not in the set of operation agents built at call time (e.g.
   the agent was removed between operation run and report download).
   Fixed with `agents_steps.setdefault(step.paw, {'steps': []})`.

2. `abilities_by_agent[link.paw]` in _get_all_possible_abilities_by_agent()
   had the same pattern — orphan paw not guarded.  Fixed with an
   explicit membership check before the extend.

3. The `except Exception` block in report() logged the error but fell
   off the end of the function, returning None implicitly.  The caller
   then returned None to web.json_response(), producing the "Null"
   download.  Fixed by re-raising so the framework returns a proper 500
   with an error body instead of a silent null payload.

Adds a regression test that constructs an operation with a chain link
whose paw is not present in operation.agents and asserts report()
returns a non-None dict that includes the orphan paw's steps.

* style: fix E303 too many blank lines in test_operation.py

* refactor: simplify double dict lookup using abilities_by_agent.get()

Fixes #3155

* style: fix E306 blank line + remove unused imports in test_rest_svc.py

* test: exercise production download_exfil_file to catch regressions in is_in_exfil_dir

Subject: [PATCH 18/25] fix: validate upload filename character set in file_svc
 (#3267)

* fix: validate upload filename character set in file_svc

Reject filenames with path traversal, null bytes, or special characters.

* fix: validate field.filename before os.path.split() to prevent traversal bypass; precompile regex; convert tests to pytest

* fix: flake8 style fixes

* fix: reject '.' as a filename and add test coverage for dot-only names

A single '.' passes the safe-character regex but is not a valid upload
filename. Add an explicit check and a parametrized test case.

* fix: consume rejected multipart part before continue to prevent reader stall

* fix: return 400 Bad Request on invalid upload filename instead of silently skipping

* fix: re-raise HTTPException so HTTPBadRequest propagates; add HTTP-level test for invalid filename

Subject: [PATCH 19/25] fix: register SIGTERM handler in run_tasks() to save
 state on service shutdown (#3018) (#3277)

* fix: register SIGTERM handler in run_tasks() to ensure teardown on service shutdown

When Caldera runs as a systemd service (or backgrounded via & / nohup),
shutdown sends SIGTERM rather than SIGINT/KeyboardInterrupt. Without a handler,
the existing 'except KeyboardInterrupt' teardown block is never reached,
so operations and other in-memory state are not saved to disk (issue #3018).

Register a SIGTERM handler at the start of run_tasks() that converts the signal
into KeyboardInterrupt, reusing the established teardown path without duplicating logic.
Tests added to verify structure (AST) and runtime behaviour.

* style: remove unused imports in test_server_sigterm.py

* fix: wrap full startup in try/except so teardown runs on SIGTERM during startup; add AST test
