Prior to 2.57.0, the GET /api/timesheets list endpoint accepts user and users[] target identifiers from a caller with view_other_timesheet but does not apply access_user or verify that a ROLE_TEAMLEAD requester leads a team containing each target user. TimesheetController::cgetAction() adds the resolved users directly to the query while project and customer filtering still permits records on unscoped projects or projects sharing ordinary team membership, allowing a teamlead to retrieve another user's descriptions, timing data, tags, rate, and internalRate even though GET /api/timesheets/{id} would deny access through TimesheetVoter. This issue is fixed in version 2.57.0.","published":"2026-09-15T11:17:09.000Z","lastModified":"2026-09-23T18:22:17.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":6.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00496,"percentile":0.4229,"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":"low","text":"Lower severity and a low EPSS score (0.50%).
