On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 19.2.1!
This is a security release, and contains the following changes:
- All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability.
It is recommended you update to this release as soon as is practical.
Additional mitigation may be required if Twisted is not your only HTTP client library:
