# CVE-2026-7168: cross-proxy Digest auth state leak

## TL;DR
cross-proxy Digest auth state leak

## Key Points
- cve / CVE-2026-7168 / severity:CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N / https://github.com/curl/curl / GIT

## Details
**Severity:** CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
**Advisory:** CVE-2026-7168

**Affected (your watchlist):**
- `GIT:https://github.com/curl/curl` curl-8_9_1 → no fixed version listed [mac]

**Details:**
Successfully using libcurl to do a transfer over a specific HTTP proxy
(`proxyA`) with **Digest** authentication and then changing the proxy host to
a second one (`proxyB`) for a second transfer, reusing the same handle, makes
libcurl wrongly pass on the `Proxy-Authorization:` header field meant for
`proxyA`, to `proxyB`.
