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-2026-27980 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- next (npm): affected from 10.0.0; fixed in 15.5.14\n- next (npm): affected from 10.0.0; fixed in 15.5.14\n- next (npm): affected from 16.0.0-beta.0; fixed in 16.1.7\n- next (npm): affected from 16.0.0-beta.0; fixed in 16.1.7\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-2026-27980/ (Markdown: https://insights.sbomify.com/CVE-2026-27980/index.md)","id":"CVE-2026-27980","markdown":"https://insights.sbomify.com/CVE-2026-27980/index.md","name":"CVE-2026-27980","record":{"aliases":["CLEANSTART-2026-DI49367","CLEANSTART-2026-LS37320","GHSA-3x4c-7xq6-9pq8","MINI-7r6h-fggg-hg3j","MINI-v227-w5cp-m84h","MINI-vpp7-6fjq-88wp","ROOT-APP-NPM-CVE-2026-27980"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Next.js framework","requires_auth":"none","summary":"Attackers can exhaust disk space by generating unique image variants, causing denial of service in Next.js applications.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"next.js","vendor":"vercel"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Next.js is a React framework for building full-stack web applications. Starting in version 10.0.0 and prior to version 16.1.7, the default Next.js image optimization disk cache (`/_next/image`) did not have a configurable upper bound, allowing unbounded cache growth. An attacker could generate many unique image-optimization variants and exhaust disk space, causing denial of service. This is fixed in version 16.1.7 by adding an LRU-backed disk cache with `images.maximumDiskCacheSize`, including eviction of least-recently-used entries when the limit is exceeded. Setting `maximumDiskCacheSize: 0` disables disk caching. If upgrading is not immediately possible, periodically clean `.next/cache/images` and/or reduce variant cardinality (e.g., tighten values for `images.localPatterns`, `images.remotePatterns`, and `images.qualities`).","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Next.js: Unbounded next/image disk cache growth can exhaust storage","id":"CVE-2026-27980","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"vercel:next.js","products":["vercel:next.js"],"type":"denial_of_service","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"HomeBox has an Auth Rate Limit Bypass via IP Spoofing","id":"CVE-2026-27981"},"packages":[{"ecosystem":"npm","fixed":["15.5.14"],"introduced":["10.0.0"],"last_affected":[],"package":"next","purl":null,"source":"GHSA-3x4c-7xq6-9pq8"},{"ecosystem":"npm","fixed":["15.5.14"],"introduced":["10.0.0"],"last_affected":[],"package":"next","purl":"pkg:npm/next","source":"GHSA-3x4c-7xq6-9pq8"},{"ecosystem":"npm","fixed":["16.1.7"],"introduced":["16.0.0-beta.0"],"last_affected":[],"package":"next","purl":null,"source":"GHSA-3x4c-7xq6-9pq8"},{"ecosystem":"npm","fixed":["16.1.7"],"introduced":["16.0.0-beta.0"],"last_affected":[],"package":"next","purl":"pkg:npm/next","source":"GHSA-3x4c-7xq6-9pq8"}],"prev":{"headline":"Next.js: Unbounded postponed resume buffering can lead to DoS","id":"CVE-2026-27979"},"products":["next.js"],"published":"2026-03-18","related":[{"cvss_score":9.1,"headline":"Authorization Bypass in Next.js Middleware","id":"CVE-2025-29927","kev_date_added":null,"published":"2025-03-21"},{"cvss_score":8.6,"headline":"Next.js: Server-side request forgery in applications using WebSocket upgrades","id":"CVE-2026-44578","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":8.3,"headline":"Next.js: Server-Side Request Forgery in Image Optimization","id":"CVE-2026-94483","kev_date_added":null,"published":"2026-10-02"},{"cvss_score":8.3,"headline":"Next.js: Middleware / Proxy bypass in App Router applications using Turbopack and single locale","id":"CVE-2026-64642","kev_date_added":null,"published":"2026-07-27"},{"cvss_score":8.3,"headline":"Next.js: Server-Side Request Forgery in rewrites via attacker-controlled destination hostname","id":"CVE-2026-64645","kev_date_added":null,"published":"2026-07-27"},{"cvss_score":8.3,"headline":"Next.js: Server-Side Request Forgery in Server Actions on Custom Servers","id":"CVE-2026-64649","kev_date_added":null,"published":"2026-07-27"},{"cvss_score":8.2,"headline":"Next.js: Denial of Service in App Router using Server Actions","id":"CVE-2026-64641","kev_date_added":null,"published":"2026-07-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-18","vendors":["vercel"]},"summary":"Attackers can exhaust disk space by generating unique image variants, causing denial of service in Next.js applications.","url":"https://insights.sbomify.com/CVE-2026-27980/"}
