{"id":"AZL-80415","summary":"CVE-2026-3099 affecting package libsoup 3.4.4-16","details":"A flaw was found in Libsoup. The server-side digest authentication implementation in the SoupAuthDomainDigest class does not properly track issued nonces or enforce the required incrementing nonce-count (nc) attribute. This vulnerability allows a remote attacker to capture a single valid authentication header and replay it repeatedly. Consequently, the attacker can bypass authentication and gain unauthorized access to protected resources, impersonating the legitimate user.","modified":"2026-08-29T05:27:27Z","published":"2026-03-12T14:16:18Z","upstream":["CVE-2026-3099"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-3099"}],"affected":[{"package":{"name":"libsoup","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libsoup"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.4.4-16"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-80415.json"}}],"schema_version":"1.9.0"}
