The flaw resides in how multipart content-type parameters are joined and serialized, enabling attackers to inject arbitrary headers or split HTTP requests when applications pass untrusted inputs to the parameters of multipart uploads.\n\n## TL;DR\nAn HTTP request/response splitting vulnerability in elixir-tesla allowed unauthenticated remote attackers to inject arbitrary headers or perform HTTP request smuggling by supplying CRLF characters to the Tesla.Multipart.add_content_type_param/2 function.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-113 (Improper Neutralization of CRLF Sequences)\n- **Attack Vector**: Local/Remote via application integration pattern\n- **CVSS v4.0 Score**: 2.1 (Low)\n- **EPSS Score**: 0.0017 (Percentile: 6.66%)\n- **Impact**: HTTP Request Splitting and Header Injection\n- **Exploit Status**: poc\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- Elixir applications utilizing the elixir-tesla HTTP client library with user-provided parameters forwarded directly to the multipart boundary or charset configuration APIs.\n- **tesla**: from 0.8.0 before 1.18.3 (Fixed in: `1.18.3`)\n\n## Mitigation\n\n- Upgrade to version 1.18.3 or higher of the tesla hex package.\n- Sanitize user-provided values passed to add_content_type_param/2 by explicitly stripping or rejecting carriage returns, line feeds, and semicolons.\n- Implement static analysis checks to detect unvalidated parameters passing from entry-points into Tesla Multipart constructs.\n\n**Remediation Steps:**\n1. Open your application's `mix.exs` configuration file.\n2. Locate the `tesla` dependency declaration in the `deps/0` list.\n3. Update the version constraint to `{:tesla, \"~> 1.18.3\"}`.\n4. Run `mix deps.update tesla` to download and lock the secured package version.\n5. Run `mix test` to confirm that standard multipart behavior remains functional.\n\n## References\n\n- [GitHub Security Advisory
