Severity: high (CVSS 7.0 v4.0)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.3% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2025-10-27 · updated 2026-10-08
Weakness: CWE-352

Description

Wimi Teamwork versions prior to 7.38.17 contains a cross-site request forgery (CSRF) vulnerability in its API. The API accepts any authenticated request that contains a JSON field named 'csrf_token' without validating the field’s value; only the presence of the field is checked. An attacker can craft a cross-site request that causes a logged-in victim’s browser to submit a JSON POST containing an arbitrary or empty 'csrf_token', and the API will execute the request with the victim’s privileges. Successful exploitation can allow an attacker to perform privileged actions as the victim potentially resulting in account takeover, privilege escalation, or service disruption.
