{"id":"GHSA-rvgh-pr46-x7gg","summary":"Gradio Vulnerable to Denial of Service (DoS) via Crafted HTTP Request","details":"A Regular Expression Denial of Service (ReDoS) vulnerability exists in the gradio-app/gradio repository, affecting the gr.Datetime component. The affected version is git commit 98cbcae. The vulnerability arises from the use of a regular expression `^(?:\\s*now\\s*(?:-\\s*(\\d+)\\s*([dmhs]))?)?\\s*$` to process user input. In Python's default regex engine, this regular expression can take polynomial time to match certain crafted inputs. An attacker can exploit this by sending a crafted HTTP request, causing the gradio process to consume 100% CPU and potentially leading to a Denial of Service (DoS) condition on the server.","aliases":["CVE-2024-10624","PYSEC-2026-1421"],"modified":"2026-07-07T17:57:03.758485640Z","published":"2025-03-20T12:32:39Z","database_specific":{"cwe_ids":["CWE-1333","CWE-400"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2025-03-20T20:39:00Z","nvd_published_at":"2025-03-20T10:15:17Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-10624"},{"type":"PACKAGE","url":"https://github.com/gradio-app/gradio"},{"type":"WEB","url":"https://github.com/gradio-app/gradio/blob/98cbcaef827de7267462ccba180c7b2ffb1e825d/gradio/components/datetime.py#L133-L136"},{"type":"WEB","url":"https://huntr.com/bounties/e8d0b248-8feb-4c23-9ef9-be4d1e868374"}],"affected":[{"package":{"name":"gradio","ecosystem":"PyPI","purl":"pkg:pypi/gradio"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.38.0"},{"last_affected":"5.0.0-beta.2"}]}],"versions":["4.38.0","4.38.1","4.39.0","4.40.0","4.41.0","4.42.0","4.43.0","4.44.0","4.44.1","5.0.0b1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-rvgh-pr46-x7gg/GHSA-rvgh-pr46-x7gg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
