{"id":"AZL-91176","summary":"CVE-2026-48142 affecting package nginx for versions less than 1.28.3-6","details":"NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module. When content is served or proxied through a location block with both source_charset utf-8; and a charset directive (for example, charset koi8-r;) configured, remote, unauthenticated attackers can send requests (in conjunction with conditions beyond their control) to cause a heap buffer over-read in the NGINX worker process, leading to limited disclosure of memory or a restart. \n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","modified":"2026-09-02T06:51:55Z","published":"2026-06-17T15:16:59Z","upstream":["CVE-2026-48142"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48142"}],"affected":[{"package":{"name":"nginx","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/nginx"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.28.3-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91176.json"}}],"schema_version":"1.9.0"}
