NVD description
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.

The 25-year one (CVE-2026-8932): For a quarter century, libcurl's connection-reuse check left out 5 client-cert settings - private key, key password, key type, cert type, key blob. Two transfers differing only there could share a connection - and an identity. https://t.co/Acujarl1GD
Post summary
A 25‑year‑old libcurl flaw (CVE‑2026‑8932) is disclosed: missing checks on five client‑certificate parameters allow connection reuse that can share identity between otherwise distinct transfers.

curl'de 2001'den kalma açık yapay zeka ile ortaya çıkarıldı: mTLS bağlantıları yanlış istemciyle yeniden kullanılabiliyordu! Aisle şirketi, yapay zeka destekli analizle libcurl'de 25 yılı aşkın süredir var olan bir açık keşfetti. CVE-2026-8932, curl 7.7'den (Mart 2001) 8.20.0'a kadar tüm sürümleri etkiliyor. • libcurl, bağlantı havuzundaki mTLS bağlantılarını yeniden kullanırken istemci sertifikası ve özel anahtar parametrelerini tam kontrol etmiyordu. • Uygulama sertifikayı değiştirse bile eski kimlik bilgileriyle açılan bağlantı riskli şekilde yeniden kullanılabiliyordu. • curl 8.21.0 sürümüyle bu dahil toplam 18 açık kapatıldı; komut satırı aracı değil, libcurl kullanan uygulamalar etkileniyor. Squidbleed'den sonra bir 25 yıllık açık daha yapay zeka ile bulundu — eski kod tabanları artık daha derin taranıyor! #SiberGüvenlik #curl #GüvenlikAçığı
