{"id":"AZL-105149","summary":"CVE-2026-93990 affecting package cmake 3.30.3-15","details":"Expat before 2.8.5 fails to validate that a high surrogate in UTF-16 input is followed by a low surrogate, allowing malformed UTF-16 sequences to be accepted. Attackers can supply UTF-16 encoded XML containing lone high surrogates that consume the following code unit, causing Expat to pass unpaired surrogates to applications built with XML_UNICODE and to silently replace input characters in other builds.","modified":"2026-10-03T05:35:10Z","published":"2026-09-19T23:17:10Z","upstream":["CVE-2026-93990"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93990"}],"affected":[{"package":{"name":"cmake","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/cmake"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.30.3-15"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105149.json"}}],"schema_version":"1.9.0"}
