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-2026-1441 in the wild and no public exploit code.\n\nAffected product: Graylog Web Interface. 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-2026-1441/ (Markdown: https://insights.sbomify.com/CVE-2026-1441/index.md)","id":"CVE-2026-1441","markdown":"https://insights.sbomify.com/CVE-2026-1441/index.md","name":"CVE-2026-1441","record":{"aliases":["GHSA-cf26-rj67-f4wr"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Graylog Web Interface","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in victims' browsers via crafted URLs in the Graylog Web Interface, potentially leading to session manipulation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[{"product":"graylog","vendor":"graylog"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Reflected Cross-Site Scripting (XSS) vulnerability in the Graylog Web Interface console, version 2.2.3, caused by a lack of proper sanitization and escaping in HTML output.
