WorkTime (on-prem/cloud), published on 19 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-15561 exists.\n\nAffected product: NesterSoft Inc. WorkTime (on-prem/cloud). 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-2025-15561/ (Markdown: https://insights.sbomify.com/CVE-2025-15561/index.md)","id":"CVE-2025-15561","markdown":"https://insights.sbomify.com/CVE-2025-15561/index.md","name":"CVE-2025-15561","record":{"aliases":["GHSA-6x8c-24f7-p33h"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"WorkTime monitoring software","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges to SYSTEM by placing a malicious executable in a world-writable directory monitored by the WorkTime daemon.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SEC-VLab","cpe":[{"product":"worktime","vendor":"nestersoft"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"An attacker can exploit the update behavior of the WorkTime monitoring daemon to elevate privileges on the local system to NT Authority\\SYSTEM.
