curl vulnerabilities

Severity: Medium · CVSS 6.8CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N
Published: Jan 1, 2025, 12:00:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 0.76% · Oct 25, 2026

When doing TLS related transfers with reused easy or multi handles and altering the `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcurl find and accept a trust chain that it otherwise would not.
