{"id":"AZL-110211","summary":"CVE-2026-87866 affecting package rust 1.96.1-2","details":"When built with wolfSSL, curl can successfully validate a pinned public key\nhash against a key the TLS peer does not possess. During the TLS handshake,\nwolfSSL validates the connection, but curl's subsequent re-parsing of the same\ncertificate - tricked by a manipulated validity length field - extracts and\nmatches a different embedded key, incorrectly authorizing the pinned public\nkey.","modified":"2026-10-27T05:36:16Z","published":"2026-10-20T21:17:20Z","upstream":["CVE-2026-87866"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-87866"}],"affected":[{"package":{"name":"rust","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.85.0"},{"last_affected":"1.96.1-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-110211.json"}}],"schema_version":"1.9.2"}
