{"schemaVersion":3,"id":"CVE-2026-14574","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In Eclipse Theia versions 0.7.0 and up until including 1.73.1, the `PreferenceUtils.merge` function in `@theia/core` recursively merges preference values without rejecting prototype-related keys (`__proto__`, `constructor`, `prototype`). Because this function is invoked by `PreferenceServiceImpl.doResolve` for every preference resolution across scopes (default, user, workspace, folder), a crafted preference value in a workspace settings file (`.theia/settings.json` or `.vscode/settings.json`) can pollute `Object.prototype` when the user opens the workspace, potentially altering application logic across the Theia process.","dates":{"published":"2026-08-05T10:51:47.869Z","modified":"2026-08-05T13:05:29.371Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":5.7,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:H/VA:L/SC:N/SI:L/SA:L","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":5.7,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:H/VA:L/SC:N/SI:L/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00395,"percentile":0.32269,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.09100000000000003,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00304},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00395,"percentile":0.32269}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00304,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00395,"percentile":null},{"date":"2026-10-05T00:00:00.
