An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2025-26399 in the wild since at least 9 Mar 2026, including in ransomware campaigns.\n\nAffected product: SolarWinds Web Help Desk. 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-2025-26399/ (Markdown: https://insights.sbomify.com/CVE-2025-26399/index.md)","id":"CVE-2025-26399","markdown":"https://insights.sbomify.com/CVE-2025-26399/index.md","name":"CVE-2025-26399","record":{"aliases":["GHSA-vfrj-f292-3f24"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"SolarWinds Web Help Desk","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution and privilege escalation via deserialization in SolarWinds Web Help Desk.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SolarWinds","cpe":[{"product":"web_help_desk","vendor":"solarwinds"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"SolarWinds Web Help Desk was found to be susceptible to an unauthenticated AjaxProxy deserialization remote code execution vulnerability that, if exploited, would allow an attacker to run commands on the host machine.
