{"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":"2026-08-12T03:51:12.989220911Z","published":"2026-03-20T02:38:41.105Z","related":["CGA-ffc7-pg6q-g6m6"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32933.json","cna_assigner":"GitHub_M","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":"1af71bfe831e337254a555a611de6c22b85d0426"},{"introduced":"8ef7df2bf8835e2ccd54338c2c5226a8c91ec628"},{"fixed":"7aea8082ca7d5dd317c2a2a455d07e7b36557a9f"},{"fixed":"0afaf1e91648fca1a57512e94dd00a76ee016816"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:luckypennysoftware:automapper:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"15.1.1"},{"introduced":"16.0.0"},{"fixed":"16.1.1"}]}}],"versions":["v16.1.1","v16.1.0","v16.0.0-beta-1","v16.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32933.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
