An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-42620 in the wild and no public exploit code.\n\nAffected product: CIRCL Vulnerability-Lookup. 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-2025-42620/ (Markdown: https://insights.sbomify.com/CVE-2025-42620/index.md)","id":"CVE-2025-42620","markdown":"https://insights.sbomify.com/CVE-2025-42620/index.md","name":"CVE-2025-42620","record":{"aliases":["GHSA-r226-j7pf-48g6"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Vulnerability-Lookup","requires_auth":"high_privilege","summary":"Stored XSS in Vulnerability-Lookup allows attackers to execute scripts in victims' browsers via unsafe comment and bundle handling.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ENISA","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In affected versions, vulnerability-lookup handled user-controlled \ncontent in comments and bundles in an unsafe way, which could lead to \nstored Cross-Site Scripting (XSS).\n\nOn the backend, the related_vulnerabilities field of bundles accepted \narbitrary strings without format validation or proper sanitization.
