{"id":"CVE-2026-32726","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-32726","generatedAt":"2026-10-28T00:15:23.828Z","title":"Prior to version 1.4.1, scitokens-cpp is vulnerable to an authorization bypass in path-based scope validation.","description":"SciTokens C++ is a minimal library for creating and using SciTokens from C or C++. Prior to version 1.4.1, scitokens-cpp is vulnerable to an authorization bypass in path-based scope validation. The enforcer used a simple string-prefix comparison when checking whether a requested resource path was covered by a token's authorized scope path. Because the check did not require a path-segment boundary, a token scoped to one path could incorrectly authorize access to sibling paths that merely started with the same prefix. This issue has been patched in version 1.4.1.","published":"2026-03-31T18:16:51.000Z","lastModified":"2026-07-24T20:10:00.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-863"],"affected":["scitokens/scitokens cpp library"],"epss":{"score":0.00272,"percentile":0.19415,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%).
