CyberRota Analysis
AI-GeneratedEtherpad versions 2.1.0 to 3.1.0 are vulnerable due to improper authorization in the OAuth path, allowing non-admin users with valid tokens to perform administrative actions such as modifying or deleting pads. This critical vulnerability can lead to unauthorized data disclosure and manipulation across the Etherpad instance. Organizations using affected versions should prioritize upgrading to version 3.1.0 to mitigate potential security risks.

Original NVD Description
Etherpad is a real-time collaborative editor. From 2.1.0 until 3.1.0, Etherpad's src/node/handler/APIHandler.ts authorizes requests to /api/2/* in the authorization_code OAuth path by using requiredClaims with the admin claim. This check requires only that the claim exists, while src/node/security/OAuth2Provider.ts issues admin: false for configured non-admin users. A non-admin user with a valid signed token can therefore invoke administrative functions including setHTML, setText, appendText, deletePad, copyPad, movePad, restoreRevision, anonymizeAuthor, listAllPads, and listAuthorsOfPad, allowing disclosure, modification, or deletion of pads across the instance. This issue is fixed in version 3.1.0.
