An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-55173 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- next (npm): affected from 0.9.9; fixed in 14.2.31\n- next (npm): affected from 0.9.9; fixed in 14.2.31\n- next (npm): affected from 15.0.0; fixed in 15.4.5\n- next (npm): affected from 15.0.0; fixed in 15.4.5\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-2025-55173/ (Markdown: https://insights.sbomify.com/CVE-2025-55173/index.md)","id":"CVE-2025-55173","markdown":"https://insights.sbomify.com/CVE-2025-55173/index.md","name":"CVE-2025-55173","record":{"aliases":["GHSA-xv57-4mr9-wg8v","MINI-mwh6-gcfm-6cgg","ROOT-APP-NPM-CVE-2025-55173"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":true,"product_category":"Next.js framework","requires_auth":"none","summary":"Attackers can inject malicious content via image optimization, enabling phishing or file delivery in specific Next.js configurations.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"next.js","vendor":"vercel"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Next.js is a React framework for building full-stack web applications.
