CVE-2025-62730: Soplanning Privilege Escalation Flaw

CVE-2025-62730 Overview

CVE-2025-62730 is a privilege escalation vulnerability in SOPlanning, an open-source online planning and scheduling tool. The flaw resides in the user management tab, where users holding the user_manage_team role can modify the permissions of other accounts. The application fails to restrict which permissions these delegated managers can grant, allowing them to assign full administrative rights to any user, including themselves. The issue affects both the Bulk Update functionality and the standard user rights editor. SOPlanning patched the flaw in version 1.55. The weakness is classified under CWE-863: Incorrect Authorization.

Critical Impact
An authenticated user with the user_manage_team role can elevate themselves to administrator, gaining full control over the SOPlanning instance and all planning data.

Affected Products

SOPlanning versions prior to 1.55
SOPlanning instances exposing the user management tab to delegated team managers
Self-hosted SOPlanning deployments with multi-role configurations

Technical Details for CVE-2025-62730

Vulnerability Analysis

The vulnerability is an authorization flaw in SOPlanning's user management interface. SOPlanning implements a role-based permission model that includes a delegated role named user_manage_team. This role is designed to allow team leads to manage members of their team without granting full administrative access.

The permission editor and the Bulk Update feature do not enforce a ceiling on which rights a user_manage_team user can assign. As a result, a delegated manager can grant any permission available in the system, including administrative flags. The server-side code processes the submitted permission set without verifying that the acting user holds an equal or higher privilege than the rights being granted.

Because the attack requires only an authenticated session with a low-privileged management role, the attack surface includes any SOPlanning deployment where the user_manage_team role is delegated to non-administrators. Successful exploitation yields administrator control over scheduling data, user accounts, and configuration.

Root Cause

The root cause is missing authorization checks on the permission assignment workflow. The application trusts that a user permitted to edit team members is also permitted to grant arbitrary rights, conflating user management with permission management.

Attack Vector

The attack is network-based and requires authentication. An attacker logs in with an account holding the user_manage_team role, opens the user management tab, edits the target account (including their own), and toggles administrative permissions. Submitting the form, either through the per-user editor or the Bulk Update action, persists the elevated rights. The next request from that account operates with administrator privileges.

See the CERT Polska advisory for technical context on the SOPlanning permission model.

Detection Methods for CVE-2025-62730

Indicators of Compromise

Unexpected accounts holding the administrator flag in the SOPlanning user table
HTTP POST requests to user edit or bulk update endpoints originating from accounts with only the user_manage_team role
Audit log entries showing permission changes where the modifier is not an existing administrator
New or recently elevated accounts performing administrative actions such as project deletion or global settings changes

Detection Strategies

Query the SOPlanning database for users whose administrator permission was set after 2025-11-20 and cross-reference with the modifying account's role
Monitor web server access logs for POST requests to user management endpoints submitted by non-admin sessions
Alert on permission deltas that grant administrative rights to accounts previously holding only standard or team roles

Monitoring Recommendations

Enable verbose application logging for the user management module and forward logs to a centralized SIEM
Build a baseline of which accounts are authorized to grant administrative rights and alert on deviations
Review SOPlanning user role assignments on a recurring schedule until the patch is applied

How to Mitigate CVE-2025-62730

Immediate Actions Required

Upgrade SOPlanning to version 1.55 or later, which contains the official fix
Audit all accounts currently holding the user_manage_team role and verify the trust level of each
Review all administrator accounts and revoke any that were elevated by a non-administrator
Reset credentials for any accounts suspected of having been used to escalate privileges

Patch Information

The vendor fixed the issue in SOPlanning 1.55. The patch enforces that a user editing permissions cannot grant rights that exceed their own. Download details are available on the SOPlanning project site.

Workarounds

Temporarily remove the user_manage_team role from all non-administrator accounts until the upgrade is complete
Restrict network access to the SOPlanning user management endpoints using reverse proxy rules or firewall ACLs
Disable the Bulk Update functionality through web server access controls if your deployment exposes it via a distinct URL path

bash

# Example: restrict access to user management endpoints at the reverse proxy
# Nginx snippet limiting /user.php and bulk update to admin source IPs
location ~ ^/(user\.php|process/bulk_update\.php) {
    allow 10.0.0.0/24;   # admin subnet
    deny all;
    proxy_pass http://soplanning_backend;
}
