Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-85089 exists.\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-2026-85089/ (Markdown: https://insights.sbomify.com/CVE-2026-85089/index.md)","id":"CVE-2026-85089","markdown":"https://insights.sbomify.com/CVE-2026-85089/index.md","name":"CVE-2026-85089","record":{"aliases":["DEBIAN-CVE-2026-85089","GHSA-3525-288q-6qj4","GHSA-v649-94v2-p72q","UBUNTU-CVE-2026-85089"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeRDP library","requires_auth":"low_privilege","summary":"FreeRDP leaks uninitialized heap memory, potentially exposing cleartext credentials, to remote peers via Save Session Info PDUs.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"freerdp","vendor":"freerdp"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"FreeRDP versions 3.0.0 through 3.30.0 (before 3.31.0) transmit uninitialized heap memory in Save Session Info PDU reserved padding fields. Three PDU writers in libfreerdp/core/info.c (rdp_write_logon_info_v2, rdp_write_logon_info_plain, and rdp_write_logon_info_ex) use Stream_Seek instead of Stream_Zero for reserved pad bytes (up to 576 bytes), leaving previously freed heap contents in the outgoing PDU. Because the send buffer is allocated with malloc (not zeroed), stale heap data — which may include cleartext credentials from prior sessions — can be sent to the receiving peer. FreeRDP-based servers using rdpUpdate::SaveSessionInfo and freerdp-proxy (which forwards these PDUs) are affected, allowing disclosure of server/proxy process memory to a downstream client.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"FreeRDP before 3.31.0 Information Disclosure via uninitialized heap memory","id":"CVE-2026-85089","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freerdp:freerdp","products":["freerdp:freerdp"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"FreeRDP before 3.31.0 Heap Out-of-Bounds Read via AVC444","id":"CVE-2026-85090"},"packages":[],"prev":{"headline":"Security feature bypass in Apache Thrift","id":"CVE-2026-85088"},"products":["FreeRDP"],"published":"2026-09-03","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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-03","vendors":["FreeRDP"]},"summary":"FreeRDP leaks uninitialized heap memory, potentially exposing cleartext credentials, to remote peers via Save Session Info PDUs.","url":"https://insights.sbomify.com/CVE-2026-85089/"}
