CVE-2026-94266
Publication date 14 October 2026
Last updated 14 October 2026
Ubuntu priority
Description
libcurl could accidentally return a URL for curl_easy_getinfo's `CURLINFO_EFFECTIVE_URL` option containing credentials, even though neither the URL provided to libcurl nor the redirected URL did. The curl tool exposes the same information using the command line option `--write-out '%{url_effective}'`. This credential leak can happen when curl retrieves credentials from a `.netrc` file.
