{"id":"PYSEC-2026-1421","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","GHSA-rvgh-pr46-x7gg"],"modified":"2026-07-07T17:47:40.971334447Z","published":"2026-07-07T14:34:51.478734Z","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"},{"type":"PACKAGE","url":"https://pypi.org/project/gradio"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-rvgh-pr46-x7gg"}],"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/pypa/advisory-database/blob/main/vulns/gradio/PYSEC-2026-1421.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
