# CVE-2025-14819: OpenSSL partial chain store policy bypass

## TL;DR
OpenSSL partial chain store policy bypass

## Key Points
- cve / CVE-2025-14819 / CURL-CVE-2025-14819 / severity:Low / https://github.com/curl/curl / GIT

## Details
**Severity:** Low
**Advisory:** CURL-CVE-2025-14819 (CVE-2025-14819)

**Affected (your watchlist):**
- `GIT:https://github.com/curl/curl` curl-8_9_1 → no fixed version listed [mac]

**Details:**
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.
