FeehiCMS Post My Comment Tab cross-site request forgery

Vulnerability

Overview A cross-site request forgery (CSRF) vulnerability has been identified in FeehiCMS, specifically within the Post My Comment Tab component. The vulnerability is classified as problematic and can be triggered remotely without authentication, exploiting the lack of CSRF protections on form submissions [1].

Attack

Vector and Exploitation The attack is launched remotely, meaning an attacker can craft a malicious web page or link that, when visited by an authenticated FeehiCMS user, will submit a forged request to the Post My Comment endpoint. This does not require direct interaction beyond the victim clicking the malicious link or loading the crafted page [1].

Impact

Successful exploitation enables the attacker to perform actions on behalf of the victim user, such as posting unauthorized comments, altering settings, or other operations the victim has permission to perform within the FeehiCMS application. This undermines the integrity of user actions and can be leveraged for further attacks like account takeover or content manipulation [1].

Mitigation

Status At the time of publication, no official patch or advisory has been released by the FeehiCMS maintainers (liufee/feehicms repository) specifically addressing this CSRF vulnerability. Users are advised to implement general CSRF countermeasures, such as using anti-CSRF tokens and validating request origins, or consider limiting comment functionality until a fix is available [2].
