RHSA-2026:82895
Vulnerability from csaf_redhat - Published: 2026-10-14 11:39 - Updated: 2026-10-17 12:55Summary
Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Important
Scope
26 vulnerabilities in this advisory, including CVE-2026-94266.
CVE-2026-94266
A flaw was found in curl. This vulnerability can lead to information disclosure by inadvertently revealing authentication credentials. When curl retrieves credentials from a local configuration file (such as a .netrc file), requesting the effective URL metadata can cause the returned destination address to improperly include those secret credentials. A local user may exploit this issue to view sensitive authentication tokens if an application or script queries and logs or displays the resolved URL.
Fixed: 13 products

UBUNTU-CVE-2026-94266 (CVE-2026-94266)
Vulnerability from osv_ubuntu – Published: 2026-10-14 06:00 – Updated: 2026-10-14 06:00 – Source website
VLAI
Details
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.
Severity
N/A (UNKNOWN)

"details": "libcurl could accidentally return a URL for curl_easy_getinfo\u0027s `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 \u0027%{url_effective}\u0027`. This credential leak can happen when curl retrieves credentials from a `.netrc` file.",
