This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. This is understood to be feasible on a local network, but not on the public internet. Privacy settings that restrict access to pages/documents on a per-user or per-group basis (as opposed to a shared password) are unaffected by this vulnerability. This has been patched in 2.7.3, 2.8.2, 2.9." } ] }, "impact": { "cvss": { "attackComplexity": "HIGH", "attackVector": "LOCAL", "availabilityImpact": "NONE", "baseScore": 6.1, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "LOW", "privilegesRequired": "HIGH", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:N", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-208: Observable Timing Discrepancy" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/wagtail/wagtail/security/advisories/GHSA-jjjr-3jcw-f8v6", "refsource": "CONFIRM", "url": "https://github.com/wagtail/wagtail/security/advisories/GHSA-jjjr-3jcw-f8v6" } ] }, "source": { "advisory": "GHSA-jjjr-3jcw-f8v6", "discovery": "UNKNOWN" } }
