An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-39253 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-39253/ (Markdown: https://insights.sbomify.com/CVE-2026-39253/index.md)","id":"CVE-2026-39253","markdown":"https://insights.sbomify.com/CVE-2026-39253/index.md","name":"CVE-2026-39253","record":{"aliases":["GHSA-78fj-q294-w4gw"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Pivotal CRM","requires_auth":"none","summary":"Remote attackers can execute arbitrary code in Pivotal CRM via unsafe deserialization in core DLL components.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/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":"An issue in Pivotal CRM v.6.6.04.08 allows a remote attacker to execute arbitrary code via the Pivotal.Core.Common.dll and Pivotal.Engine.Client.Services.Conversion.dll components.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-23T12:26:03Z","kind":"github_poc","ref":"https://github.com/timtimxs/CVE-2026-39253-Advisory","stars":0,"title":"Public advisory for CVE-2026-39253, addressing an insecure deserialisation in Pivotal CRM 6.6.04.08 allowing remote code execution via unsafe BinaryFormatter usage in Smart Client and PBS components.
