The flaw resides in the 'Tesla.Middleware.FollowRedirects' component, which performs case-sensitive lookups when stripping credentials during cross-origin redirects. Because HTTP headers are case-insensitive by RFC specifications, standard canonical casing (e.g., 'Authorization') bypasses the lowercase-only blocklist, leaking tokens to untrusted external redirect destinations.\n\n## TL;DR\nCase-sensitive header filtering in Tesla's FollowRedirects middleware fails to strip credentials like 'Authorization' during cross-origin redirects if they contain uppercase characters, leading to token leakage to untrusted hosts.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-178\n- **Attack Vector**: Network (Remote)\n- **CVSS v4 Score**: 8.2 (High)\n- **EPSS Score**: 0.00396 (0.40%)\n- **Exploit Status**: Proof of Concept (PoC) Publicly Available\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- Elixir systems integrating the elixir-tesla/tesla library with active follow-redirect modules.\n- **tesla**: >= 1.4.0, < 1.18.3 (Fixed in: `1.18.3`)\n\n## Mitigation\n\n- Upgrade the elixir-tesla/tesla dependency to version 1.18.3 or greater.\n- Normalize all outgoing HTTP header keys to lowercase at the application layer prior to dispatching requests.\n- Sanitize client-provided redirection inputs to avoid cross-origin redirection routes.\n\n**Remediation Steps:**\n1. Open your project's mix.exs configuration file.\n2. Locate the {:tesla, ...} dependency definition.\n3. Modify the version constraint to requiring '~> 1.18.3' or greater.\n4. Execute 'mix deps.get' in your shell to fetch the updated packages.\n5. Rebuild and run tests to ensure no regression occurs.\n\n## References\n\n- [GitHub Security Advisory -
