{"id":"CVE-2024-10624","aliases":["PYSEC-2026-1421"],"url":"https://o3.security/vulnerability/CVE-2024-10624","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.","published":"2025-03-20T12:32:39Z","modified":"2026-07-07T17:57:03.758485640Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"gradio","fixedVersion":null}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-07T17:57:03.758485640Z"}}
