CVE-2026-86415auto client cert connection reuse mixup

curl curl Veröffentlicht: (vor 23 Tagen)

Beschreibung

libcurl's connection cache match function never considers the automatic client certificate option, so a cached, already authenticated Schannel connection can be handed to a transfer that got redirected to a different origin, even though the code explicitly switched off the auto client cert option for that transfer to prevent exactly this.

Schwachstellentyp (CWE): CWE-201

Daten: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Wiedergegeben wie in der Quelle, auf Englisch.
