CVE-2026-82378 Details
Description
Incorrect Authorization in the OAuth 1.0a authorization endpoint of Apache Roller 6.1.5 allows an unauthenticated remote attacker who learns an outstanding request token for a configured site-wide consumer to bind that token to an arbitrary user account, including an administrator, by submitting an unsigned authorization request. The endpoint derives the authorizing identity from a request-supplied value rather than the authenticated session. Only installations that configure an OAuth 1.0a site-wide consumer are affected, and exploitation requires knowledge of one of its outstanding request tokens. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which binds authorization to the logged-in session.
A vulnerability in the OAuth 1.0a authorization endpoint of Apache Roller version 6.1.5 allows an unauthenticated remote attacker to bind an outstanding request token to any user account, including administrators. This is achieved by submitting an unsigned authorization request. The vulnerability arises because the endpoint relies on request-supplied values to determine the authorizing identity, instead of using the authenticated session. Only installations with a configured OAuth 1.0a site-wide consumer are affected, and exploitation requires knowledge of an outstanding request token.
Users are advised to upgrade to Apache Roller version 6.1.6 or later, which addresses this vulnerability by binding authorization to the logged-in session.
