Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-27294 exists.\n\nAffected product: OpenCATS. 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-2023-27294/ (Markdown: https://insights.sbomify.com/CVE-2023-27294/index.md)","id":"CVE-2023-27294","markdown":"https://insights.sbomify.com/CVE-2023-27294/index.md","name":"CVE-2023-27294","record":{"aliases":["GHSA-85f4-cmhq-rx89"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCATS ATS","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious JavaScript into calendar event descriptions, leading to session theft or forced actions for other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"opencats","vendor":"opencats"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of input during web page generation allows an authenticated attacker with access to a restricted account to submit malicious Javascript as the description for a calendar event, which would then be executed in other users' browsers if they browse to that event.
