CVE-2026-82208

This vulnerability affects libcurl built with the wolfSSL backend, in releases 8.9.1 through 8.21.0 . When CA caching is enabled and an application uses CURLOPT_SSL_CTX_FUNCTION to replace the trust store, a logic error in Curl_wssl_setup_x509_store() (lib/vtls/wolfssl.c) silently reinstalls the ...

CVE-2026-82208 wolfSSL CA-cache hit overrides callback

With the wolfSSL backend, when CA caching is enabled and an CURLOPTSSLCTXFUNCTION callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectl...

CVE-2026-80231

libcurl wrongly reuses an existing HTTPS connection for a given hostname even when the Native CA Store setting (CURLSSLOPT_NATIVE_CA) differs from that used when the connection was originally created. The root cause is that the connection-reuse key omitted the Native CA Store setting; a fix (comm...
