HTTP client library vulnerabilities

A vulnerability in cross-origin redirect handling causes Proxy-Authorization and Proxy-Authenticate headers to persist, potentially leaking sensitive authentication data.

Response body and chunk parsing would handle non-hex or negative integers incorrectly, which could result in misinterpreting HTTP response contents. This may cause incorrect data processing by the HTTP client.

A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed, trusted vendor URL at initialization and does not process attacker-controlled input through the library.
