It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-8558 in the wild and no public exploit code.\n\nAffected product: Proofpoint Insider Threat Management (ITM) Server. 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-2025-8558/ (Markdown: https://insights.sbomify.com/CVE-2025-8558/index.md)","id":"CVE-2025-8558","markdown":"https://insights.sbomify.com/CVE-2025-8558/index.md","name":"CVE-2025-8558","record":{"aliases":["GHSA-5mj6-fm92-ww5m"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Insider Threat Management Server","requires_auth":"none","summary":"Unauthenticated adjacent network users can unregister agents when license limits are exceeded, causing loss of event data and availability.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Proofpoint","cpe":[{"product":"insider_threat_management_server","vendor":"proofpoint"}],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Insider Threat Management (ITM) Server versions prior to 7.17.2 contain an authentication bypass vulnerability that allows unauthenticated users on an adjacent network to perform agent unregistration when the number of registered agents exceeds the licensed limit.
