CVE-2026-86409

curl vulnerabilities

Severity: Medium · CVSS 5.3CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N
Published: Oct 13, 2026, 10:00:00 PM UTC
Source: [NVD] · [CVE record]
EPSS: 0.26% · Oct 25, 2026

Setting `CURLOPT_AWS_SIGV4` to NULL but does not disable SigV4 authentication, contrary to expectations and documentation. A subsequent transfer on the same handle still sends an `Authorization: AWS4-HMAC-SHA256` header to whatever URL isset next, leaking state information.
