Notion data leak exposes editor emails in public page source code. Researcher weezerOSINT (@weezerOSINT) flagged it via X post on October 9, 2024.
Crypto markets signal fear. Fear & Greed Index sits at 27 (Alternative.me, Oct 10, 2024). BTC trades at $74,983 (-1.0% 24h), ETH at $2,300.03 (-2.3%) (CoinGecko, Oct 10, 2024, 14:00 UTC).
The issue hits Notion's 30 million users (Notion blog, Q2 2024 earnings). Fintech firms and crypto projects use public Notion pages for wikis, roadmaps, and tokenomics docs.
How the Notion Data Leak Works
Public Notion pages list contributors without authentication. Page source code reveals full editor emails in metadata JSON. WeezerOSINT demonstrated on a sample public page. No login required.
Verification: I replicated the leak inspecting source code of public Notion pages from crypto projects (verified Oct 10, 2024). Emails appear as "user_email": "editor@example.com" in plain text.
Notion enables public sharing for collaboration. But metadata exposure bypasses privacy settings. Integrations with Slack, Google Workspace, and Zapier raise risks (Notion API docs, v2024-09-01).
Key Security Risks from Email Exposure
Phishers target leaked emails for spear-phishing at crypto wallets. BTC at $74,983 (CoinGecko, Oct 10, 2024) means wallet theft risks millions. Spam and reputational damage follow.
Notion's security page lists encryption at rest (Notion, Oct 10, 2024). It ignores public metadata leaks. Enterprises audit SaaS tools (Gartner, Q3 2024 report).
Crypto Fear & Greed Index at 27/100 shows extreme fear (Alternative.me methodology, data since 2018).

Why Productivity Tools Face Attacks
Notion serves 30 million users in AI, fintech, crypto (Notion blog, 2024 metrics). Public pages host API docs, decks, DeFi roadmaps.
Attackers chain leaks to phishing and API theft. Precedent: 2023 LastPass breach hit 30M users (Have I Been Pwned, Oct 2024).
EU MiCA (Jan 30, 2026, eur-lex.europa.eu) demands secure data. U.S. SEC probes third-party risks (SEC.gov, FY2024 report).
Crypto teams link Notion in whitepapers. Leaked emails enable dev targeting for private keys.
Mitigation Steps for Users
1. Audit public pages. Remove unneeded editors. 2. Use view-only links over full public access. 3. Enable 2FA on Notion and linked accounts. 4. Check breaches at Have I Been Pwned (Troy Hunt, Oct 2024). 5. Use DLP tools like Microsoft Purview.
Alternatives: Coda (metadata privacy) or ClickUp (permissions).
Implications for Fintech, Crypto
Leak erodes SaaS trust. Fintech needs tamper-proof docs. IPFS blocks metadata leaks (protocol.ipfs.io).
Fear & Greed at 27 signals BTC corrections (Alternative.me, 2018-2024). Notion needs metadata fixes.
Markets eye volatility. BTC market cap: $1.50T. Verify pages now. Expect Notion response soon.
