* fix(security): deny generated-image access when ownership verification fails The except Exception block in serve_generated_image catches all exceptions during ownership verification and falls through to serve the file anyway. If the database is down or corrupted, the ownership check is bypassed entirely — any authenticated user can download any generated image by guessing the content-hash filename. Raise HTTP 503 (Service Unavailable) instead of falling through, so the endpoint fails closed when verification is impossible. This matches the defense-in-depth principle: deny access on verification errors rather than granting it. * fix(security): enforce fail-closed ownership and secure caching for generated images - Fail closed on missing gallery records, null/empty owners, and DB errors - Support both cookie session and bearer API token owners via effective_user - Add in-memory registry for freshly generated images to preserve access - Eliminate file existence oracle by verifying ownership before disk probing - Update Cache-Control to private, no-cache, must-revalidate - Pass owner attribution through tool execution and image MCP server - Add comprehensive hermetic regression tests for ownership gates and caching * fix(security): sanitize tool owner arguments and drop unneeded MCP env fallback - Remove redundant and unsafe ODYSSEUS_MCP_IMAGE_OWNER fallback in image_gen_server.py to fix 4 tests in test_env_reference.py. - Sanitize caller-supplied tool arguments across all MCP and email tool dispatch paths in src/tool_execution.py: strip untrusted _odysseus_* keys from arguments. - Only inject _odysseus_owner when verified trusted server context is present, preventing untrusted/anonymous users from spoofing ownership claims. - Sanitize empty/whitespace owner strings in image_gen_server.py to None. - Add comprehensive regression tests in test_generated_image_ownership.py for argument sanitization, owner injection, fallback propagation, and server sanitization. --------- Co-authored-by: isharak7m <192635824+isharak7m@users.noreply.github.com> Co-authored-by: PR #6166 Reviewer <reviewer@odysseus-review.local> |
