{"id":"BIT-nginx-2026-27784","summary":"NGINX ngx_http_mp4_module vulnerability","details":"The 32-bit implementation of NGINX Open Source has a vulnerability in the ngx_http_mp4_module module, which might allow an attacker to over-read or over-write NGINX worker memory resulting in its termination, using a specially crafted MP4 file. The issue only affects 32-bit NGINX Open Source if it is built with the ngx_http_mp4_module module and the mp4 directive is used in the configuration file. Additionally, the attack is possible only if an attacker can trigger the processing of a specially crafted MP4 file with the ngx_http_mp4_module module. \n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","aliases":["BIT-nginx-gateway-2026-27784","CVE-2026-27784"],"modified":"2026-09-08T08:47:44.454575259Z","published":"2026-03-27T07:10:08.052Z","database_specific":{"cpes":["cpe:2.3:a:f5:nginx:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"ADVISORY","url":"https://my.f5.com/manage/s/article/K000160364"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27784"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:10065"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:13634"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:13680"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:13839"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:14836"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:15942"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:15943"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:15945"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:15966"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:6906"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:6907"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:6923"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:7002"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:7343"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:8346"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-27784"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2450785"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-27784.json"}],"affected":[{"package":{"name":"nginx","ecosystem":"Bitnami","purl":"pkg:bitnami/nginx"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.1.19"},{"fixed":"1.28.3"},{"introduced":"1.29.0"},{"fixed":"1.29.7"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/nginx/BIT-nginx-2026-27784.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
