{"id":"AZL-105141","summary":"CVE-2026-17545 affecting package php 8.3.33-1","details":"On Windows, PHP's filesystem and stream APIs do not reject reserved device names such as CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9, CONIN$ and CONOUT$ when they appear as a component of a path. An attacker-controlled filename therefore reaches CreateFileW() and opens a device instead of the regular file the application expected, which can block or hang the request and exhaust worker processes.","modified":"2026-10-03T05:35:10Z","published":"2026-09-25T21:17:23Z","upstream":["CVE-2026-17545"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-17545"}],"affected":[{"package":{"name":"php","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/php"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"8.3.33-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105141.json"}}],"schema_version":"1.9.0"}
