It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-30785 exists.\n\nAffected product: rustdesk-client RustDesk Client. 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-2026-30785/ (Markdown: https://insights.sbomify.com/CVE-2026-30785/index.md)","id":"CVE-2026-30785","markdown":"https://insights.sbomify.com/CVE-2026-30785/index.md","name":"CVE-2026-30785","record":{"aliases":["GHSA-v738-924g-mm67"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"RustDesk remote desktop","requires_auth":"low_privilege","summary":"Attackers can decrypt local passwords using a world-readable machine ID and fixed nonce, exposing sensitive credentials in RustDesk Client.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VULSec","cpe":[{"product":"rustdesk","vendor":"rustdesk"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-916","name":"Use of Password Hash With Insufficient Computational Effort"},{"id":"CWE-323","name":"Reusing a Nonce, Key Pair in Encryption"},{"id":"CWE-257","name":"Storing Passwords in a Recoverable Format"},{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), Use of Password Hash With Insufficient Computational Effort vulnerability in rustdesk-client RustDesk Client rustdesk, hbb_common on Windows, MacOS, Linux (Password security module, config encryption, machine UID modules) allows Retrieve Embedded Sensitive Data.
