An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54223 in the wild and no public exploit code.\n\nAffected product: UBB.threads. 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-2026-54223/ (Markdown: https://insights.sbomify.com/CVE-2026-54223/index.md)","id":"CVE-2026-54223","markdown":"https://insights.sbomify.com/CVE-2026-54223/index.md","name":"CVE-2026-54223","record":{"aliases":["GHSA-jgf8-gg7j-fq24"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"UBB.threads forum","requires_auth":"high_privilege","summary":"Privileged attackers can exploit path traversal in UBB.threads to read/write arbitrary files, leading to remote code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"UBB.threads is vulnerable to Path traversal, allowing attackers with privilege to edit templates to read and write any file on the application’s server that application has privileges to, what results in Remote Code Execution. \nBecause vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 7.7.5 but may also affect other versions.","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":"Remote Code Execution via arbitrary file read and write in UBB.threads","id":"CVE-2026-54223","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of Service in UBB.threads","id":"CVE-2026-54224"},"packages":[],"prev":{"headline":"Blind SQL Injection in UBB.threads","id":"CVE-2026-54222"},"products":["UBB.threads"],"published":"2026-06-18","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":"total"},"state":"PUBLISHED","updated":"2026-06-18","vendors":["UBB Systems"]},"summary":"Privileged attackers can exploit path traversal in UBB.threads to read/write arbitrary files, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-54223/"}
