An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-50461 exists.\n\nAffected product: n/a. 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-2025-50461/ (Markdown: https://insights.sbomify.com/CVE-2025-50461/index.md)","id":"CVE-2025-50461","markdown":"https://insights.sbomify.com/CVE-2025-50461/index.md","name":"CVE-2025-50461","record":{"aliases":["GHSA-xhf5-3r9v-mm67"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Volcengine verl library","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into loading malicious model files in the Volcengine verl library's model merger script.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A deserialization vulnerability exists in Volcengine's verl 3.0.0, specifically in the scripts/model_merger.py script when using the \"fsdp\" backend. The script calls torch.load() with weights_only=False on user-supplied .pt files, allowing attackers to execute arbitrary code if a maliciously crafted model file is loaded. An attacker can exploit this by convincing a victim to download and place a malicious model file in a local directory with a specific filename pattern. This vulnerability may lead to arbitrary code execution with the privileges of the user running the script.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-08-15","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-08-15T06:26:57Z","kind":"github_poc","ref":"https://github.com/Anchor0221/CVE-2025-50461","stars":0,"title":"Technical Details and Exploit for CVE-2025-50461"}],"tier":"weaponised"},"has_fix":null,"headline":"Deserialization in n/a","id":"CVE-2025-50461","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2025-50464"},"packages":[],"prev":{"headline":"MS SWIFT Remote Code Execution via unsafe PyYAML deserialization","id":"CVE-2025-50460"},"products":["n/a"],"published":"2025-08-19","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-08-19","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by tricking users into loading malicious model files in the Volcengine verl library's model merger script.","url":"https://insights.sbomify.com/CVE-2025-50461/"}
