Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-8080 in the wild and no public exploit code.\n\nAffected product: Misp-Project Misp. 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-2026-8080/ (Markdown: https://insights.sbomify.com/CVE-2026-8080/index.md)","id":"CVE-2026-8080","markdown":"https://insights.sbomify.com/CVE-2026-8080/index.md","name":"CVE-2026-8080","record":{"aliases":["GHSA-3v62-pvrh-853r"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing","requires_auth":"low_privilege","summary":"Stored XSS in MISP old template engine allows attackers with template modification rights to execute scripts in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[{"product":"misp","vendor":"misp-project"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/U:Green","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in misp allows Stored XSS.\n\nThis issue affects MISP before 2.5.37.\n\nA stored cross-site scripting vulnerability exists in the template element attribute handling logic.
