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-2026-68579 in the wild and no public exploit code.\n\nAffected product: Freerdp Freerdp. 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-2026-68579/ (Markdown: https://insights.sbomify.com/CVE-2026-68579/index.md)","id":"CVE-2026-68579","markdown":"https://insights.sbomify.com/CVE-2026-68579/index.md","name":"CVE-2026-68579","record":{"aliases":["DEBIAN-CVE-2026-68579","GHSA-m4j8-6wj9-56fg","UBUNTU-CVE-2026-68579"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeRDP client","requires_auth":"none","summary":"A malicious RDP server can trigger a heap overflow in the FreeRDP client during clipboard paste operations, potentially allowing remote code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"freerdp","vendor":"freerdp"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"FreeRDP before 3.30.0 (\u003c= 3.29.0) contains a heap-based buffer overflow in the Windows clipboard client's CliprdrStream_Read function (client/Windows/wf_cliprdr.c). When an OLE paste consumer (e.g. explorer.exe) calls IStream::Read with a fixed-size buffer of cb bytes, CliprdrStream_Read requests file contents from the RDP server and then copies the response into the caller's buffer using the server-supplied length (req_fsize) instead of cb. A malicious or compromised RDP server can return an oversized CB_FILECONTENTS_RESPONSE, causing an out-of-bounds write of attacker-controlled data into the paste consumer's heap buffer when a user pastes server-offered clipboard file contents.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"FreeRDP before 3.30.0 Heap Overflow via CliprdrStream_Read","id":"CVE-2026-68579","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freerdp:freerdp","products":["freerdp:freerdp"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"FreeRDP before 3.29.0 Integer Overflow via Audio Input Channel","id":"CVE-2026-68580"},"packages":[],"prev":{"headline":"ArcadeDB before 26.7.3 Authentication Bypass via MCP Transport","id":"CVE-2026-68578"},"products":["FreeRDP"],"published":"2026-08-02","related":[{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37594","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37595","kev_date_added":null,"published":"2021-07-27"},{"cvss_score":9.4,"headline":"FreeRDP Windows Client before 3.29.0 Heap Buffer Overflow via Cliprdr","id":"CVE-2026-67305","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 TLS Certificate Identity Validation Bypass","id":"CVE-2026-66402","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 HTTP Proxy Request Injection via Redirection","id":"CVE-2026-67289","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 WebSocket Ping Buffer Over-disclosure","id":"CVE-2026-67292","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":9.3,"headline":"FreeRDP before 3.29.0 Improper Certificate Hostname Validation","id":"CVE-2026-67293","kev_date_added":null,"published":"2026-08-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-03","vendors":["FreeRDP"]},"summary":"A malicious RDP server can trigger a heap overflow in the FreeRDP client during clipboard paste operations, potentially allowing remote code execution.","url":"https://insights.sbomify.com/CVE-2026-68579/"}
