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-2026-103648 in the wild and no public exploit code.\n\nAffected product: demsking image-downloader. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-103648/ (Markdown: https://insights.sbomify.com/CVE-2026-103648/index.md)","id":"CVE-2026-103648","markdown":"https://insights.sbomify.com/CVE-2026-103648/index.md","name":"CVE-2026-103648","record":{"aliases":["GHSA-h4gg-43m2-62cm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js image downloader","requires_auth":"none","summary":"An attacker controlling the download URL can write files outside the intended directory, potentially overwriting critical system files.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Path traversal in image-downloader 4.3.0 allows an attacker who can control the download URL to cause downloaded response data to be written outside the configured destination directory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-03","github_poc":1,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-03T12:03:52Z","kind":"github_poc","ref":"https://github.com/EterNullSec/CVE-2026-103648","stars":2,"title":"CVE-2026-103648 | Path Traversal in image-downloader 4.3.0 | CVSS 9.1 Critical | CWE-22 | By EterNullSec"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in image-downloader","id":"CVE-2026-103648","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Synchronous Access of Remote Resource without Timeout in hMailServer","id":"CVE-2026-103649"},"packages":[],"prev":{"headline":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in hMailServer","id":"CVE-2026-103647"},"products":["image-downloader"],"published":"2026-10-02","related":[],"sources":[{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-03","vendors":["demsking"]},"summary":"An attacker controlling the download URL can write files outside the intended directory, potentially overwriting critical system files.","url":"https://insights.sbomify.com/CVE-2026-103648/"}
