It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-4255 in the wild and no public exploit code.\n\nAffected product: thermalright TR-VISION HOME. 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-2026-4255/ (Markdown: https://insights.sbomify.com/CVE-2026-4255/index.md)","id":"CVE-2026-4255","markdown":"https://insights.sbomify.com/CVE-2026-4255/index.md","name":"CVE-2026-4255","record":{"aliases":["GHSA-f62h-6jmm-8r9r"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Thermalright TR-VISION HOME","requires_auth":"none","summary":"Local attackers can escalate privileges by placing a malicious DLL in a user-writable directory, causing the application to load it with administrative rights.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Toreon","cpe":[{"product":"tr-vision_home","vendor":"thermalright"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-829","name":"Inclusion of Functionality from Untrusted Control Sphere"}],"description":"A DLL search order hijacking vulnerability in Thermalright TR-VISION HOME on Windows (64-bit) allows a local attacker to escalate privileges via DLL side-loading. The application loads certain dynamic-link library (DLL) dependencies using the default Windows search order, which includes directories that may be writable by non-privileged users.\\n\\n\\n\\nBecause these directories can be modified by unprivileged users, an attacker can place a malicious DLL with the same name as a legitimate dependency in a directory that is searched before trusted system locations. When the application is executed, which is always with administrative privileges, the malicious DLL is loaded instead of the legitimate library.\\n\\n\\n\\nThe application does not enforce restrictions on DLL loading locations and does not verify the integrity or digital signature of loaded libraries. As a result, attacker-controlled code may be executed within the security context of the application, allowing arbitrary code execution with elevated privileges.\\n\\n\\n\\nSuccessful exploitation requires that an attacker place a crafted malicious DLL in a user-writable directory that is included in the application's DLL search path and then cause the affected application to be executed. Once loaded, the malicious DLL runs with the same privileges as the application.\\n\\n\\n\\nThis issue affects \\nTR-VISION HOME  versions up to and including 2.0.5.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-05-09","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-05-09T19:05:16Z","kind":"github_poc","ref":"https://github.com/Ard33/CVE-2026-4255","stars":1,"title":null}],"tier":"poc_unverified"},"has_fix":null,"headline":"DLL Injection Privilege Escalation","id":"CVE-2026-4255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"LDAP Injection in PEAKUP's PassGate","id":"CVE-2026-4256"},"packages":[],"prev":{"headline":"Tenda AC8 HTTP Endpoint SysToolChangePwd doSystemCmd stack-based overflow","id":"CVE-2026-4254"},"products":["TR-VISION HOME"],"published":"2026-03-16","related":[],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-16","vendors":["thermalright"]},"summary":"Local attackers can escalate privileges by placing a malicious DLL in a user-writable directory, causing the application to load it with administrative rights.","url":"https://insights.sbomify.com/CVE-2026-4255/"}
