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-2026-44483 exists.\n\nAffected packages and fixed versions:\n- @rvf/set-get (npm): affected from 6.0.0; fixed in 6.0.4\n- @rvf/set-get (npm): affected from 6.0.0; fixed in 6.0.4\n- @rvf/set-get (npm): affected from 7.0.0; fixed in 7.0.2\n- @rvf/set-get (npm): affected from 7.0.0; fixed in 7.0.2\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-2026-44483/ (Markdown: https://insights.sbomify.com/CVE-2026-44483/index.md)","id":"CVE-2026-44483","markdown":"https://insights.sbomify.com/CVE-2026-44483/index.md","name":"CVE-2026-44483","record":{"aliases":["GHSA-c567-44rc-m5hq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"React form validation library","requires_auth":"none","summary":"Attackers can pollute Object.prototype via form data, potentially leading to remote code execution or privilege escalation in React applications using RVF.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"RVF (formerly Remix Validated Form) provides easy form validation and state management for React. From 6.0.0 to before 6.0.4 and 7.0.2, setPath in @rvf/set-get (used by @rvf/core to flatten incoming form data into a nested object) does not block the keys __proto__, constructor, or prototype when walking a path. Because field names in submitted form data are passed directly to setPath via preprocessFormData (and through parseFormData / validate), an attacker who can submit a form to a Remix / React Router app using the library can set arbitrary properties on Object.prototype of the running server process. This is a default-reachable prototype pollution primitive: no special configuration is required. Any endpoint that accepts a form via parseFormData or runs a validator created with createValidator is affected. This vulnerability is fixed in 6.0.4 and 7.0.2.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"RVF: Prototype pollution in @rvf/set-get reachable via @rvf/core preprocessFormData (HTTP form data)","id":"CVE-2026-44483","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":4,"n_references":1,"next":{"headline":"Compromise of PyTorch Lightning PyPi Package Versions","id":"CVE-2026-44484"},"packages":[{"ecosystem":"npm","fixed":["6.0.4"],"introduced":["6.0.0"],"last_affected":[],"package":"@rvf/set-get","purl":null,"source":"GHSA-c567-44rc-m5hq"},{"ecosystem":"npm","fixed":["6.0.4"],"introduced":["6.0.0"],"last_affected":[],"package":"@rvf/set-get","purl":"pkg:npm/%40rvf/set-get","source":"GHSA-c567-44rc-m5hq"},{"ecosystem":"npm","fixed":["7.0.2"],"introduced":["7.0.0"],"last_affected":[],"package":"@rvf/set-get","purl":null,"source":"GHSA-c567-44rc-m5hq"},{"ecosystem":"npm","fixed":["7.0.2"],"introduced":["7.0.0"],"last_affected":[],"package":"@rvf/set-get","purl":"pkg:npm/%40rvf/set-get","source":"GHSA-c567-44rc-m5hq"}],"prev":{"headline":"soundcloud-rpc: Remote Code Execution via XSS in Track Title","id":"CVE-2026-44482"},"products":["rvf","set-get"],"published":"2026-05-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["@rvf","airjp73"]},"summary":"Attackers can pollute Object.prototype via form data, potentially leading to remote code execution or privilege escalation in React applications using RVF.","url":"https://insights.sbomify.com/CVE-2026-44483/"}
