{"id":"CVE-2026-32933","summary":"AutoMapper Vulnerable to Denial of Service (DoS) via Uncontrolled Recursion","details":"AutoMapper is a convention-based object-object mapper in .NET. Versions prior to 15.1.1 and 16.1.1 are vulnerable to a Denial of Service (DoS) attack. When mapping deeply nested object graphs, the library uses recursive method calls without enforcing a default maximum depth limit. This allows an attacker to provide a specially crafted object graph that exhausts the thread's stack memory, triggering a `StackOverflowException` and causing the entire application process to terminate. Versions 15.1.1 and 16.1.1 fix the issue.","aliases":["GHSA-rvv3-g6hj-g44x"],"modified":"2026-04-10T05:43:07.176790Z","published":"2026-03-20T02:38:41.105Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32933.json","cwe_ids":["CWE-674"]},"references":[{"type":"WEB","url":"https://github.com/LuckyPennySoftware/AutoMapper/releases/tag/v15.1.1"},{"type":"WEB","url":"https://github.com/LuckyPennySoftware/AutoMapper/releases/tag/v16.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32933.json"},{"type":"ADVISORY","url":"https://github.com/LuckyPennySoftware/AutoMapper/security/advisories/GHSA-rvv3-g6hj-g44x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32933"},{"type":"FIX","url":"https://github.com/LuckyPennySoftware/AutoMapper/commit/0afaf1e91648fca1a57512e94dd00a76ee016816"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/luckypennysoftware/automapper","events":[{"introduced":"0"},{"fixed":"0afaf1e91648fca1a57512e94dd00a76ee016816"}]},{"type":"GIT","repo":"https://github.com/luckypennysoftware/automapper","events":[{"introduced":"0"},{"fixed":"1af71bfe831e337254a555a611de6c22b85d0426"}]},{"type":"GIT","repo":"https://github.com/luckypennysoftware/automapper","events":[{"introduced":"0"},{"fixed":"7aea8082ca7d5dd317c2a2a455d07e7b36557a9f"}]}],"versions":["v1.0","v1.1","v10.0.0","v10.1.0","v10.1.1","v11.0.0","v11.0.1","v12.0.0","v12.0.1","v13.0.0","v13.0.1","v14.0.0","v15.0.0","v15.0.1","v15.1.0","v16.0.0","v16.0.0-beta-1","v16.1.0","v16.1.1","v2.0.0","v2.1.267","v2.2.0","v2.2.1","v3.0.0","v3.1.0","v3.1.1","v3.2.0","v3.2.1","v3.3.0","v3.3.1","v4.0.0","v4.0.0-alpha1","v4.0.1","v4.0.2","v4.0.3","v4.0.4","v4.1.0","v4.1.1","v4.2.0","v4.2.1","v5.0.0","v5.0.0-beta-1","v5.0.1","v5.0.2","v5.1.0","v5.1.1","v5.2.0","v6.0.0","v6.0.1","v6.0.2","v6.1.0","v6.1.1","v6.2.0","v6.2.1","v6.2.2","v7.0.0","v7.0.0-alpha-0001","v7.0.1","v8.0.0","v8.1.0","v8.1.1","v9.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32933.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
