CVE-2025-4673
MediumSummary
A vulnerability in cross-origin redirect handling causes Proxy-Authorization and Proxy-Authenticate headers to persist, potentially leaking sensitive authentication data.
Risk Assessment
An attacker could intercept proxy credentials during a redirect to a malicious domain, enabling unauthorized access to network resources.
Recommendation
Update the software to the latest version that includes a fix to clear these headers on cross-origin redirects.
Other vulnerabilities in HTTP client library
See all- CVE-2026-103995Low
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.
- CVE-2026-90455Low
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.
Original NVD description (English source)
