An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-66480 in the wild and no public exploit code.\n\nAffected product: wildfirechat im-server. 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-2025-66480/ (Markdown: https://insights.sbomify.com/CVE-2025-66480/index.md)","id":"CVE-2025-66480","markdown":"https://insights.sbomify.com/CVE-2025-66480/index.md","name":"CVE-2025-66480","record":{"aliases":["GHSA-74hq-jhx2-fq6c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Wildfire IM server","requires_auth":"none","summary":"Attackers can upload malicious files to arbitrary locations via directory traversal in Wildfire IM, leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"im-server","vendor":"wildfirechat"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Wildfire IM is an instant messaging and real-time audio/video solution. Prior to 1.4.3, a critical vulnerability exists in the im-server component related to the file upload functionality found in com.xiaoleilu.loServer.action.UploadFileAction. The application exposes an endpoint (/fs) that handles multipart file uploads but fails to properly sanitize the filename provided by the user. Specifically, the writeFileUploadData method directly concatenates the configured storage directory with the filename extracted from the upload request without stripping directory traversal sequences (e.g., ../../). This vulnerability allows an attacker to write arbitrary files to any location on the server's filesystem where the application process has write permissions. By uploading malicious files (such as scripts, executables, or overwriting configuration files like authorized_keys or cron jobs), an attacker can achieve Remote Code Execution (RCE) and completely compromise the server. This vulnerability is fixed in 1.4.3.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Wildfire has Arbitrary File Upload via Directory Traversal in UploadFileAction","id":"CVE-2025-66480","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"DeepChat's Incomplete XSS Fix Allows RCE through Mermaid Content","id":"CVE-2025-66481"},"packages":[],"prev":{"headline":"Anthropic Sandbox Runtime Incorrectly Implemented Network Sandboxing","id":"CVE-2025-66479"},"products":["im-server"],"published":"2026-02-02","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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-03","vendors":["wildfirechat"]},"summary":"Attackers can upload malicious files to arbitrary locations via directory traversal in Wildfire IM, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2025-66480/"}
