{"id":"CVE-2026-82377","published":"2026-09-28T08:16:41.417","lastModified":"2026-09-29T16:17:12.010","description":"Missing Authorization in Apache Roller 6.1.5 allows an authenticated user to read, modify, or delete weblog content belonging to other weblogs through the legacy XML-RPC Blogger and MetaWeblog APIs, because the handlers authenticate the caller but do not verify the caller's permission on the weblog or entry actually affected. Only installations that enable the non-default global XML-RPC setting are affected; the per-weblog API flag defaults to enabled for UI-created weblogs. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which applies an explicit per-method permission check, or to keep the XML-RPC feature disabled.","cvssScore":9.9,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/roller/pull/164","tags":[]},{"url":"https://lists.apache.org/thread/phxx56n0w6jjqzto2my3ot8hto0qjvn8","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/25/10","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/roller/pull/164","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an authenticated user to read, modify, or delete content from other weblogs via the XML-RPC APIs, due to missing permission checks. This is critical as it can lead to unauthorized access and data manipulation.","exploitability":"Exploitation is relatively straightforward for an authenticated user with access to the XML-RPC APIs. The attacker must have valid credentials for the affected installation.","blast_radius":"If exploited, this can result in significant data loss or tampering, affecting multiple weblogs on the same installation.","remediation":"Upgrade to Apache Roller 6.1.6 or later, which applies explicit per-method permission checks.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","api","xml-rpc"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-28T08:47:35.088Z"}}
