{"id":"GHSA-rhx6-c78j-4q9w","summary":"path-to-regexp contains a ReDoS","details":"### Impact\n\nThe regular expression that is vulnerable to backtracking can be generated in versions before 0.1.12 of `path-to-regexp`, originally reported in CVE-2024-45296\n\n### Patches\n\nUpgrade to 0.1.12.\n\n### Workarounds\n\nAvoid using two parameters within a single path segment, when the separator is not `.` (e.g. no `/:a-:b`). Alternatively, you can define the regex used for both parameters and ensure they do not overlap to allow backtracking.\n\n### References\n\n- https://github.com/advisories/GHSA-9wv6-86v2-598j\n- https://blakeembrey.com/posts/2024-09-web-redos/","aliases":["CVE-2024-52798"],"modified":"2026-07-17T21:15:02.986448929Z","published":"2024-12-05T22:40:47Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-12-05T22:40:47Z","nvd_published_at":"2024-12-05T23:15:06Z","cwe_ids":["CWE-1333"]},"references":[{"type":"WEB","url":"https://github.com/pillarjs/path-to-regexp/security/advisories/GHSA-rhx6-c78j-4q9w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-52798"},{"type":"WEB","url":"https://github.com/pillarjs/path-to-regexp/commit/f01c26a013b1889f0c217c643964513acf17f6a4"},{"type":"WEB","url":"https://blakeembrey.com/posts/2024-09-web-redos"},{"type":"PACKAGE","url":"https://github.com/pillarjs/path-to-regexp"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20250124-0002"}],"affected":[{"package":{"name":"path-to-regexp","ecosystem":"npm","purl":"pkg:npm/path-to-regexp"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.1.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-rhx6-c78j-4q9w/GHSA-rhx6-c78j-4q9w.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"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P"}]}
