{"id":"GHSA-p5wg-g6qr-c7cg","summary":"Withdrawn Advisory: eslint has a Stack Overflow when serializing objects with circular references","details":"## Withdrawn Advisory\nThis advisory has been withdrawn because RuleTester is used for testing rules during development and results in a error rather than crashing the application.\n\n## Original Description\n\nThere is a Stack Overflow vulnerability in eslint before 9.26.0 when serializing objects with circular references in `eslint/lib/shared/serialization.js`. The exploit is triggered via the `RuleTester.run()` method, which validates test cases and checks for duplicates. During validation, the internal function `checkDuplicateTestCase()` is called, which in turn uses the `isSerializable()` function for serialization checks. When a circular reference object is passed in, `isSerializable()` enters infinite recursion, ultimately causing a Stack Overflow.","aliases":["CVE-2025-50537"],"modified":"2026-09-10T03:50:33.506829960Z","published":"2026-01-26T18:31:29Z","withdrawn":"2026-02-03T17:43:56Z","database_specific":{"cwe_ids":["CWE-674"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-01-29T14:58:17Z","nvd_published_at":"2026-01-26T16:15:58Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-50537"},{"type":"WEB","url":"https://github.com/eslint/eslint/issues/19646"},{"type":"WEB","url":"https://github.com/eslint/eslint/commit/d683aebc8e0792e4f80bd1488c705c90f22c317e"},{"type":"WEB","url":"https://gist.github.com/lyyffee/2ee1815e5c2da82c05e9838b9bfefbbc"},{"type":"PACKAGE","url":"https://github.com/eslint/eslint"}],"affected":[{"package":{"name":"eslint","ecosystem":"npm","purl":"pkg:npm/eslint"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.26.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/01/GHSA-p5wg-g6qr-c7cg/GHSA-p5wg-g6qr-c7cg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
