CVE-2025-6380
ONLYOFFICE Docs 1.1.0 - 2.2.0 - Missing Authorization to Unauthenticated Privilege Escalation via callback Function
CVE-2025-6380 is a critical vulnerability (CVSS 9.8) in Onlyoffice Docs, published July 24, 2025. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.85%, the 58th percentile. No source names a fixed version.
The ONLYOFFICE Docs plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization within its oo.callback REST endpoint in versions 1.1.0 to 2.2.0. The plugin’s permission callback only verifies that the supplied, encrypted attachment ID maps to an existing attachment post, but does not verify the requester’s identity or capabilities. This makes it possible for unauthenticated attackers to log in as an arbitrary user.
