{"id":"AZL-99783","summary":"CVE-2026-82209 affecting package cmake 3.30.3-15","details":"When libpsl support is enabled, libcurl fails to enforce the Public Suffix\nList boundary check when processing a `Set-Cookie` header where the `Domain`\nattribute explicitly matches an origin host that is itself a public suffix\n(e.g., `Domain=co.uk` set by `co.uk`).\n\nInstead of coercing it into a strict host-only cookie, libcurl saves the\ncookie with wildcard domain scope (`.co.uk`). Consequently, the cookie is\ninappropriately included in subsequent outbound requests or HTTP redirects to\narbitrary sibling subdomains under the same public suffix (e.g.,\n`attacker.co.uk`).","modified":"2026-09-08T12:40:45.184348Z","published":"2026-09-06T18:17:22Z","upstream":["CVE-2026-82209"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82209"}],"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-99783.json"}}],"schema_version":"1.9.0"}
