CVE-2025-63691

Exp

In pig-mesh In Pig version 3.8.2 and below, within the Token Management function under the System Management module, the token query interface (/api/admin/sys-token/page) has an improper permission verification issue, which leads to information leakage. This interface can be called by any user who has completed login authentication, and it returns the plaintext authentication Tokens of all users currently logged in to the system. As a result, ordinary users can obtain the administrator's authentication Token through this interface, thereby forging an administrator account, gaining the system's management permissions, and taking over the system.

Base score Version Severity Vector Exploitability Impact Score source
9.6 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
