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-2026-15176 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nginx (Bitnami): affected from 0.1.29; fixed in 1.30.6, 1.31.7\n- nginx-gateway (Bitnami): affected from 0.1.29; fixed in 1.30.6, 1.31.7\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-2026-15176/ (Markdown: https://insights.sbomify.com/CVE-2026-15176/index.md)","id":"CVE-2026-15176","markdown":"https://insights.sbomify.com/CVE-2026-15176/index.md","name":"CVE-2026-15176","record":{"aliases":["ALPINE-CVE-2026-15176","AZL-108446","BELL-CVE-2026-15176","BIT-nginx-2026-15176","BIT-nginx-gateway-2026-15176","CLSA-2026-1792146840","CLSA-2026-1792164102","CLSA-2026-1792164686","CLSA-2026-1792165116","CLSA-2026-1792170794","CLSA-2026-1792426319","CLSA-2026-1792579760","CLSA-2026-1792580147","CLSA-2026-1792580871","CLSA-2026-1792770638","CLSA-2026-1792798495","DEBIAN-CVE-2026-15176","ECHO-2330-430e-59fe","GHSA-cvv4-j4mx-w8q5","ROOT-OS-DEBIAN-12-CVE-2026-15176","UBUNTU-CVE-2026-15176"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"NGINX web server","requires_auth":"none","summary":"Remote attackers can cause denial of service or potentially execute code via heap buffer overflow in NGINX when specific alias and rewrite configurations are used.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability exists in NGINX Plus and NGINX Open Source when a location is configured that uses the alias directive together with rewrite and a set or return directive referencing the $request_filename variable. Alternatively, the same result could be achieved when the $request_filename variable is used in an access log format directive. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.\n\nImpact:\nThis vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-10-27","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-27T13:36:49Z","kind":"github_poc","ref":"https://github.com/FranklinF25/cve-2026-15176","stars":1,"title":"CVE-2026-15176 — NGINX alias+rewrite heap overflow: analysis, differential lab, PoC (WIP)"}],"tier":"poc_unverified"},"has_fix":true,"headline":"NGINX ngx_http_core_module vulnerability","id":"CVE-2026-15176","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Fluent Forms \u003c= 6.2.5 - Missing Authorization to Authenticated (Custom+) Sensitive Data Exposure and Modification","id":"CVE-2026-15178"},"packages":[{"ecosystem":"Bitnami","fixed":["1.30.6","1.31.7"],"introduced":["0.1.29","1.31.0"],"last_affected":[],"package":"nginx","purl":"pkg:bitnami/nginx","source":"BIT-nginx-2026-15176"},{"ecosystem":"Bitnami","fixed":["1.30.6","1.31.7"],"introduced":["0.1.29","1.31.0"],"last_affected":[],"package":"nginx-gateway","purl":"pkg:bitnami/nginx-gateway","source":"BIT-nginx-gateway-2026-15176"}],"prev":{"headline":"Heap-based Buffer Overflow in Wireshark","id":"CVE-2026-15174"},"products":["NGINX Open Source","NGINX Plus"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["F5"]},"summary":"Remote attackers can cause denial of service or potentially execute code via heap buffer overflow in NGINX when specific alias and rewrite configurations are used.","url":"https://insights.sbomify.com/CVE-2026-15176/"}
