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-2026-107396 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- indico (PyPI): affected all versions; fixed in 3.3.13\n- indico (PyPI): affected all versions; fixed in 3.3.13\n- indico (PyPI): affected all versions; fixed in 3.3.13\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-2026-107396/ (Markdown: https://insights.sbomify.com/CVE-2026-107396/index.md)","id":"CVE-2026-107396","markdown":"https://insights.sbomify.com/CVE-2026-107396/index.md","name":"CVE-2026-107396","record":{"aliases":["GHSA-c4wc-ggrj-jg9v","PYSEC-2026-4227"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Indico event management","requires_auth":"low_privilege","summary":"Attackers can inject malicious JavaScript via crafted URLs in event fields, allowing script execution in victims' browsers within the Indico origin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-692","name":"Incomplete Denylist to Cross-Site Scripting"}],"description":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask.
