CVE-2026-8932

Assigner-curl

Assigner Org ID-2499f714-1537-4658-8207-48ae4bb9eae9

Published At-03 Jul, 2026 | 06:16

Updated At-03 Jul, 2026 | 06:16

incomplete mTLS config matching in conn reuse

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS settings related to client certificates were left out from the configuration match checks, making them match too easily. In particular options related to the private key.
