CVE-2026-105031

When using the OpenSSL TLS implementation, both the pnssldomainsettrustedcadb() & pntlsconfigsettrustedcerts() APIs added to rather than replaced the default system trust anchors. Leading to potentially trusting unexpected peer certificates. This can be worked around by setting the SSLCERTFILE environment variable for the application to /dev/null. This issue does not affect the Win32 SChannel TLS implementation. This issue affects Apache Qpid Proton C: through 0.40.0. Users are recommended to upgrade to version 0.41.1, which fixes the issue.
