Summary

• add signed iat/exp, an eight-hour default lifetime, a configurable session version, request-time allowlist/admin demotion checks, and an explicit logout flow
• reject cookie-authenticated mutations unless Origin or Referer matches the configured dashboard origin; bearer MCP and signed webhook ingress remain outside that check
• stream webhook bodies with an incremental hard cap and add a matching 1 MiB limit to the nginx example
• make the current MCP trust decision explicit: token ownership controls lifecycle management, while repository knowledge remains deployment-global like the dashboard read model

Security and rollout notes

• Legacy dashboard cookies have no expiry claim and are intentionally rejected after this update, so existing users must authenticate again.
• Direct user/admin allowlist removals take effect on the next request. Organization/team membership is refreshed at the next OAuth login, bounded by the configured absolute session lifetime.
• Incrementing GITHUB_AGENT_BRIDGE_DASHBOARD_SESSION_VERSION revokes all outstanding sessions without rotating the signing key.
• The application-level webhook cap is effective with this code. The proxy-side cap requires deploying the updated nginx configuration; this PR does not change production configuration or claim rollout completion.
• MCP knowledge is intentionally global within one bridge database. The UI and docs now call token users lifecycle owners rather than implying a repository ACL. Mutually untrusted tenants must not share the database/endpoint; a future repository ACL must cover both dashboard and MCP.

Tests

• python3 -m pytest -q — 713 passed
• cd dashboard && npm test — 79 passed
• cd dashboard && npm run build

Fixes #339

Reviewed f02e243 against #339 and the existing dashboard/webhook trust boundaries. Approve.

The signed session now has an absolute expiry and version, rejects legacy cookies, rechecks configured allowlists on each request, and demotes admins after direct allowlist removal. Cookie-authenticated mutations use a fail-closed same-origin check; the signed webhook and bearer MCP routes remain outside it. Webhook bodies are capped incrementally, and the MCP deployment-global knowledge model is stated explicitly rather than implying a per-user repository ACL.

Validation: PYTHONPATH=src /home/openclaw/.openclaw/workspace/github/github-agent-bridge/.venv/bin/python -m pytest -q tests/test_backend.py tests/test_webhook.py — 175 passed. GitHub Python 3.11/3.12 and dashboard checks are green. The proxy-side 1 MiB cap still needs the nginx configuration deployed, as the PR notes; this is an operational rollout step, not a code-review blocker.

Post-merge sync complete: #340 is merged as fce118c (head f02e243). The dedicated, clean github-agent-bridge-pr-340 worktree was removed and its absence verified; the canonical checkout was left untouched. Python 3.11/3.12 and dashboard CI jobs passed. The two agent status checks were still pending at this check, so this does not claim a completed rollout; the nginx body limit still requires deployment of the updated proxy configuration, as noted in the PR.

Post-merge follow-up: PR #340 is merged at fce118c7 and CI was green (pytest 3.11/3.12 and dashboard). The dedicated worktree github-agent-bridge-issue-339 was clean and has been removed; the canonical checkout was left untouched.

Operational follow-up remains separate from code completion: deploy the updated nginx configuration to enforce the proxy-side 1 MiB webhook cap, then observe it in production.
