Apollo Portal versions before 2.5.0 do not verify application and namespace permissions when an authenticated user requests a release by ID through GET /envs/{env}/releases/{releaseId}.
When configView.memberOnly.envs is enabled for the requested environment, a low-privileged Portal user can supply a valid release ID belonging to an application or namespace they are not authorized to view. The endpoint returns the release data without calling UserPermissionValidator.shouldHideConfigToCurrentUser(...).
An authenticated attacker who obtains or guesses a valid release ID can read configuration data from other applications and namespaces. Exposed configuration may contain sensitive values such as credentials or service endpoints. The issue does not allow configuration modification and does not directly affect availability.
Apollo Portal versions earlier than 2.5.0 are affected when configView.memberOnly.envs is enabled.
The issue is fixed in Apollo 2.5.0. The fix adds the missing application and namespace permission check before returning release data.
Upgrade to Apollo 2.5.0 or later. If an immediate upgrade is not possible, backport the permission check from PR #5378 and restrict Apollo Portal access to trusted users until the fix is deployed.
Apollo Portal thanks @lesignals for reporting this issue.
