Prior to 1.8.0-beta.27, a privilege escalation vulnerability exists in Grav\u2019s Admin plugin due to the absence of username uniqueness validation when creating users. A user with the create user permission can create a new account using the same username as an existing administrator account, set a new password/email, and then log in as that administrator. This effectively allows privilege escalation from limited user-manager permissions to full administrator access. This vulnerability is fixed in 1.8.0-beta.27."}], "lastModified": "2025-12-04T18:33:10.217", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:getgrav:grav:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4F55C0B3-A41D-4E64-A631-E4868A40A8A5", "versionEndExcluding": "1.8.0", "versionStartIncluding": "1.7.49.5"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8A383F2E-C6BA-440B-B648-A3313B7D91C3"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta10:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F7EF2DEC-2798-4D0D-9C27-0F01BAFEAEFD"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta11:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "530C6F64-F30B-4E93-9A12-D9625EA57483"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta12:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9AC28BF9-626D-4514-91F0-F81DAB5D3602"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta13:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "307AA375-E531-4AE5-BA79-2F9D4DE7A05F"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta14:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C2E3E312-485D-42B0-B465-64B6438CDCAE"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta15:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5BE4B2F9-1B6D-4D18-916A-5C95A3213222"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta16:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "763207F0-92D1-4274-A30A-DE634C5852C3"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta17:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1DE8F350-BA07-4DAA-AE4B-5E0A532B6828"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta18:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F9150B94-0DF3-43F3-9806-39787A6C0E4D"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta19:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "BAA7C7EC-8FB2-445D-8A02-1743D87F5416"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7A6BEA2A-D534-4C9E-811A-8A46E214C46D"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta20:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7A644F57-FF39-4262-9796-7C4F3B0851C1"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta21:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B2AFB9E7-084E-497B-B0FC-CA6A5033C5BF"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta22:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5C5E8823-9083-4FFA-9897-CAD0340DCE68"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta23:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9C048938-E0EC-4AD0-9847-FD74E6770FE2"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta24:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F7B43876-1445-418A-9707-E692FDF62C4D"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta25:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "94B209DE-01C6-41BA-B912-CF57849A9F7A"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta26:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AB53AA10-87A5-4010-8019-BF4AA5ABC12B"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "775E0913-F3EF-4A55-B162-5BF9C6E2E641"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta4:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3C3E022E-35CB-40AD-959A-F39949E38BD3"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta5:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8779C813-A81A-4E21-AB86-6193933568BC"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta6:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B608EDD4-207A-41A7-A60D-496FDA8EAFEA"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta7:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AE1F2253-3EE0-4ADD-B8A5-C882A60FC626"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta8:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "81D4C859-5560-42F1-ACD9-65210E523F28"}, {"criteria": "cpe:2.3:a:getgrav:grav:1.8.0:beta9:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "156707A7-9507-4AC1-9CD0-90E32836E9DF"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
