An attacker can exploit it over the internet without logging in, 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-2023-53957 exists.\n\nAffected packages and fixed versions:\n- kimai/kimai (Packagist): affected all versions up to 1.30.10; no fix listed\n- kimai/kimai (Packagist): affected all versions up to 1.30.10; no fix listed\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-2023-53957/ (Markdown: https://insights.sbomify.com/CVE-2023-53957/index.md)","id":"CVE-2023-53957","markdown":"https://insights.sbomify.com/CVE-2023-53957/index.md","name":"CVE-2023-53957","record":{"aliases":["GHSA-cv8h-r7r5-vwj9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Kimai time tracking","requires_auth":"none","summary":"Attackers can hijack user sessions in Kimai by exploiting missing SameSite cookie protections, allowing unauthorized access to victim accounts.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"kimai","vendor":"kimai"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1275","name":"Sensitive Cookie with Improper SameSite Attribute"}],"description":"Kimai 1.30.10 contains a SameSite cookie vulnerability that allows attackers to steal user session cookies through malicious exploitation.
