An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-78417 in the wild and no public exploit code.\n\nAffected product: Devolutions Remote Desktop Manager. 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-2026-78417/ (Markdown: https://insights.sbomify.com/CVE-2026-78417/index.md)","id":"CVE-2026-78417","markdown":"https://insights.sbomify.com/CVE-2026-78417/index.md","name":"CVE-2026-78417","record":{"aliases":["GHSA-v5j9-gh53-cfjx"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Remote Desktop Manager","requires_auth":"none","summary":"An on-path attacker can intercept and tamper with VNC sessions due to automatic acceptance of server RSA keys in Devolutions Remote Desktop Manager.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DEVOLUTIONS","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Insufficient verification of data authenticity in the IronVNC client in Devolutions Remote Desktop Manager 2026.2.17.0 and earlier, 2026.1.24.0 and earlier, allows an on-path attacker to intercept and tamper with VNC sessions via automatic acceptance of the server's RSA key during RSA-AES authentication.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Security feature bypass in Remote Desktop Manager","id":"CVE-2026-78417","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"zbus_polkit: polkit authorization bypass via PID reuse due to incorrect D-Bus type for the subject UID","id":"CVE-2026-78422"},"packages":[],"prev":{"headline":"Authenticated RCE via `condition.config` JSON cleanse bypass","id":"CVE-2026-78416"},"products":["Remote Desktop Manager"],"published":"2026-08-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["Devolutions"]},"summary":"An on-path attacker can intercept and tamper with VNC sessions due to automatic acceptance of server RSA keys in Devolutions Remote Desktop Manager.","url":"https://insights.sbomify.com/CVE-2026-78417/"}
