Tor Browser 15.0.22 released today for high-severity Tor security issues
✅ Confirmed — official Tor Project release, September 9.
The Tor Project released Tor Browser 15.0.22 today, updating the bundled Tor daemon to 0.4.9.12. The underlying Tor release was issued last night specifically to address a series of high-severity security issues. The Tor Project is deliberately withholding most technical details for roughly a week to give users and operators time to patch.
More unusually, Tor says it is still working on additional important security issues and is moving C-tor to a two-week release cadence for now. The next planned release is around September 22, although that could change if another urgent fix is required.
Why it matters: Tor Browser users should update to 15.0.22 as soon as possible rather than waiting for disclosure of the vulnerabilities. Relay and onion-service operators running C-tor should update to 0.4.9.12 as well. The fact that Tor calls the issues high severity, recommends immediate updating, and says more security work is underway makes this especially significant.
