{"id":"AZL-94095","summary":"CVE-2026-66338 affecting package libsoup 3.4.4-16","details":"A flaw was found in libsoup. The chunked transfer encoding parser uses a permissive parsing function for chunk sizes that silently accepts inputs violating RFC 9112, including leading whitespace, plus sign prefixes, and trailing invalid characters. When libsoup operates behind a strict frontend proxy, this parsing differential can be exploited to smuggle HTTP requests.","modified":"2026-08-30T05:26:50Z","published":"2026-07-24T23:16:52Z","upstream":["CVE-2026-66338"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66338"}],"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-94095.json"}}],"schema_version":"1.9.0"}
