CVE-2026-8927
None
No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
When reusing a libcurl handle for sequential transfers driven by
environment-variable proxy configuration, libcurl fails to clear the proxy
authentication state between requests. Specifically, if the initial transfer
authenticates against
proxyA using Digest auth, a subsequent transfer routed
through proxyB erroneously leaks the Proxy-Authorization: header intended
solely for proxyA. Found an issue in the description? Have something to add? Feel free to write us 👾
