An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48142 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nginx (Bitnami): affected from 1.0.0; fixed in 1.30.3, 1.31.2\n- nginx-gateway (Bitnami): affected from 1.0.0; fixed in 1.30.3, 1.31.2\n- nginx-gateway-fabric (Bitnami): affected from 1.3.0; fixed in 2.6.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-48142/ (Markdown: https://insights.sbomify.com/CVE-2026-48142/index.md)","id":"CVE-2026-48142","markdown":"https://insights.sbomify.com/CVE-2026-48142/index.md","name":"CVE-2026-48142","record":{"aliases":["ALPINE-CVE-2026-48142","AZL-91176","BELL-CVE-2026-48142","BIT-nginx-2026-48142","BIT-nginx-gateway-2026-48142","BIT-nginx-gateway-fabric-2026-48142","CLSA-2026-1785327397","CLSA-2026-1785327873","CLSA-2026-1785328094","DEBIAN-CVE-2026-48142","ECHO-b826-4d3a-4f4e","GHSA-2388-jp8v-fg9w","MINI-2p68-8w8q-r4pf","MINI-4r8f-7v4q-4m5f","MINI-8fmv-fcc8-vr4f","MINI-h9fv-9g7r-8xp3","MINI-mc8g-9m5q-wfr7","MINI-xwhv-m24f-59m2","UBUNTU-CVE-2026-48142"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"NGINX web server","requires_auth":"none","summary":"Remote attackers can trigger a heap buffer over-read in NGINX when specific charset configurations are used, leading to memory disclosure or service restart.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"dos","vendor":"f5"},{"product":"nginx_gateway_fabric","vendor":"f5"},{"product":"nginx_ingress_controller","vendor":"f5"},{"product":"nginx_instance_manager","vendor":"f5"},{"product":"nginx_open_source","vendor":"f5"},{"product":"nginx_plus","vendor":"f5"},{"product":"waf","vendor":"f5"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module.
