What to do
AI-suggested
Red Hat has released updated RPM packages for curl and related components to address these vulnerabilities. Users should apply these updates as provided by Red Hat Hardened Images. Additionally, to mitigate the risk of OAuth2 bearer token leakage, administrators should carefully manage .netrc files, avoiding entries for untrusted or unknown hosts, especially when curl is configured to follow redirects with OAuth2 tokens. Regularly reviewing and restricting credentials stored in .netrc files is recommended.
Description
A security advisory from Red Hat addresses vulnerabilities in Red Hat Hardened Images RPMs, specifically in curl and libcurl packages. One notable issue (CVE-2026-3783) involves the potential leakage of OAuth2 bearer tokens during HTTP(S) redirects when curl follows redirects and .netrc files contain entries for the redirected host. This could lead to unauthorized disclosure of sensitive tokens. The advisory provides updated RPM packages to fix these issues.
