{"id":"GHSA-rwcr-rpcc-3g9m","summary":"elixir-nodejs has Cross-User Data Leakage or Information Disclosure due to Worker Protocol Race Condition","details":"### Impact\n\nThis vulnerability results in Cross-User Data Leakage or Information Disclosure due to a race condition in the worker protocol.\n\nThe lack of request-response correlation creates a \"stale response\" vulnerability. Because the worker does not verify which request a response belongs to, it may return the next available data in the buffer to an unrelated caller.\n\nIn high-throughput environments where the library processes sensitive user data (e.g., PII, authentication tokens, or private records), a timeout or high concurrent load can cause Data A (belonging to User A) to be returned to User B.\n\nThis may lead to unauthorized information disclosure that is difficult to trace, as the application may not throw an error but instead provide \"valid-looking\" yet entirely incorrect and private data to the wrong session.\n\n### Patches\n\nfixed in v3.1.4\n\n### Resources\nhttps://github.com/revelrylabs/elixir-nodejs/issues/100\n\nhttps://github.com/revelrylabs/elixir-nodejs/pull/105","aliases":["CVE-2026-33872"],"modified":"2026-03-27T22:04:54.690820Z","published":"2026-03-26T18:23:01Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-26T18:23:01Z","nvd_published_at":"2026-03-27T20:16:34Z","cwe_ids":["CWE-362"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/revelrylabs/elixir-nodejs/security/advisories/GHSA-rwcr-rpcc-3g9m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33872"},{"type":"WEB","url":"https://github.com/revelrylabs/elixir-nodejs/issues/100"},{"type":"WEB","url":"https://github.com/revelrylabs/elixir-nodejs/pull/105"},{"type":"PACKAGE","url":"https://github.com/revelrylabs/elixir-nodejs"},{"type":"WEB","url":"https://github.com/revelrylabs/elixir-nodejs/releases/tag/v3.1.4"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Hex","purl":"pkg:hex/nodejs"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.1.4"}]}],"versions":["0.1.0","0.2.0","0.2.1","0.2.2","0.2.3","1.0.0","1.1.0","2.0.0","3.0.0","3.1.0","3.1.1","3.1.2","3.1.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-rwcr-rpcc-3g9m/GHSA-rwcr-rpcc-3g9m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
