security: fix 12 vulnerabilities across CRITICAL→LOW severity
Closes CodeQL alerts #12, #13, #14, #15, #16, #17, #18 CRITICAL - fix(media_parser): replace eval() with fractions.Fraction for fps parsing (CWE-95) - fix(agent_memory): replace pickle serialization with JSON to prevent RCE (CWE-502) HIGH - fix(snowflake_ingestor): parameterize LIMIT/OFFSET, validate ORDER BY with regex, reject semicolons in WHERE to prevent SQL injection (CWE-89) - fix(rdf_parser): add defusedxml XXE protection for RDF/XML format parsing (CWE-611) - fix(server): add CORSMiddleware, security response headers middleware (X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, Referrer-Policy, Permissions-Policy, HSTS), and global error handler (CWE-346, CWE-200) - fix(explorer/app): narrow CORS to specific methods/headers, redact exception messages in HTTP error handlers, enforce 64 KB WebSocket message size cap (CWE-346) MEDIUM - fix(graph): replace free-text algorithm param with _PathAlgorithm enum (CWE-20) - fix(vocabulary): validate uploaded file extensions against allowlist (CWE-434) - fix(llm_extraction): json.dumps() all user content in LLM prompts to block prompt-injection attacks (CWE-1336) - fix(pipeline_validator): replace __import__("collections") with proper import (CWE-95) LOW - fix(sparql): cap results at 5 000 rows and enforce 30-second query timeout (CWE-400) - fix(export_import): validate file extension + enforce 50 MB upload limit (CWE-434) CodeQL / scanning - feat(codeql): add .github/codeql/codeql-config.yml to exclude generated cookbook HTML bundles (Plotly + MapLibre) from JS scanning - feat(codeql): extend dismiss-fixed-alerts job with all new rule IDs (py/path-injection, py/polynomial-redos, js/incomplete-url-substring-sanitization, js/insecure-randomness, js/prototype-pollution-utility) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
