CVE-2026-107831 in Jivejdon
Summary
by MITRE • 10/09/2026
Jivejdon through 5.0 contains a cross-site request forgery vulnerability that allows remote attackers to perform state-changing actions by abusing GET endpoints lacking anti-CSRF tokens. Attackers can lure authenticated users to crafted links targeting /account/protected/delAll, /account/protected/sub/delSub, or /message/updateAction to delete private messages and subscriptions or rename threads.

The vulnerability identified in Jivejdon versions up to 5.0 represents a classic Cross-Site Request Forgery (CSRF) flaw rooted in the improper implementation of state-changing operations via HTTP GET requests. In secure web application design, any action that modifies server-side data or user-specific settings must be protected against unauthorized initiation from external sources. However, Jivejdon fails to enforce anti-CSRF tokens on several critical endpoints responsible for managing private messages and thread subscriptions. This architectural oversight allows an attacker to craft malicious URLs containing specific parameters that trigger these sensitive actions without the victim's knowledge or consent. The core technical failure lies in the reliance solely on HTTP method types rather than implementing robust authentication mechanisms like synchronized CSRF tokens, which are required to verify that a request originates from a legitimate user session within the application context.
The operational impact of this vulnerability is significant for users who rely on Jivejdon for private communication and community engagement. By exploiting these unprotected GET endpoints, an attacker can force authenticated users to perform destructive actions such as deleting all their private messages or removing specific subscriptions. Furthermore, the ability to rename threads through the /message/updateAction endpoint introduces a layer of social engineering risk, potentially causing confusion among other forum participants by altering thread titles without authorization. Since these operations are executed via GET requests, they can be easily embedded in images, hyperlinks, or hidden form submissions on malicious websites. When an authenticated user visits such a site while still logged into Jivejdon, their browser automatically includes session cookies with the request, thereby authenticating the forged action as legitimate from the server's perspective.
From a classification standpoint, this vulnerability aligns directly with CWE-352, which defines Cross-Site Request Forgery as an attack that forces an end user to execute unwanted actions on a web application in which they are currently authenticated. The specific exploitation technique leverages the browser's automatic inclusion of credentials for same-site requests, bypassing intended access controls due to the lack of additional verification steps like unique per-session tokens. In terms of adversary behavior mapping under MITRE ATT&CK, this falls under T1566.002, which covers Spearphishing Link attacks where attackers lure victims into clicking a malicious link that triggers state-changing actions on trusted sites. The exploitation does not require complex injection techniques but rather relies on social engineering to get the victim to initiate the request, making it particularly dangerous in community-driven platforms where trust among users is high.
To mitigate this vulnerability, developers must immediately implement anti-CSRF tokens for all endpoints that modify application state or user data. This involves generating a unique, unpredictable token per session and requiring its presence as either a form parameter or an HTTP header value during POST requests used for deletion or modification operations. Additionally, it is advisable to change the implementation of these actions from GET to POST methods, adhering to RESTful principles where safe idempotent operations use GET while state-changing ones utilize non-safe verbs like POST, PUT, or DELETE. This shift alone provides a layer of protection because many browsers and proxies do not automatically send credentials with cross-origin POST requests initiated by third-party sites unless specifically configured to do so. Furthermore, implementing the SameSite cookie attribute for session cookies can significantly reduce the risk by preventing browsers from sending these cookies in cross-site request contexts, thereby neutralizing the primary vector used by CSRF attackers.
