CVE-2026-8458wrong reuse for different services

curl curl Veröffentlicht: (vor 4 Monaten)

Beschreibung

libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated ones, even when they are set to use different "services". libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead. When reusing a connection a range of criteria must be met. Due to a logical error in the code, a request that was issued by an application could wrongfully reuse an existing connection to the same server that was authenticated using different services.

Schwachstellentyp (CWE): CWE-488
