A cross-site request forgery (CSRF) vulnerability has been identified in SourceCodester Diary App versions 1.0. This flaw allows an attacker to trick authenticated users into performing actions they did not intend to, potentially leading to unauthorized data modification or deletion. The vulnerability resides within an unknown function of the diary.php file and has been publicly disclosed.
The primary impact of this CSRF vulnerability is the potential for unauthorized actions to be performed on a user's account. An attacker could craft malicious links or embed them in websites or emails, enticing users to click them. Upon clicking, the attacker can execute actions as the user, such as creating, modifying, or deleting diary entries. The blast radius is limited to the scope of actions available within the Diary App, but the potential for data compromise and account takeover remains significant. While no specific real-world precedent is immediately apparent, CSRF vulnerabilities are commonly exploited in web applications.
This vulnerability has been publicly disclosed, increasing the likelihood of exploitation. The CVSS score of 4.3 (MEDIUM) indicates a moderate level of severity and suggests a reasonable probability of exploitation. No known active campaigns targeting this specific vulnerability have been reported at the time of writing. The CVE was published on 2026-03-27.
Users of SourceCodester Diary App version 1.0, particularly those who rely on the application for sensitive data storage or management, are at risk. Shared hosting environments where Diary App is installed are also at increased risk, as vulnerabilities in one application can potentially impact other applications on the same server.

curl -I 'http://your-diary-app/diary.php?action=some_action¶m=some_value' | grep 'referer'• generic web:

The recommended mitigation is to upgrade to a patched version of Diary App as soon as it becomes available. Until a patch is released, consider implementing CSRF protection mechanisms such as synchronizer tokens or double-submit cookies. These techniques add an extra layer of verification to ensure that requests originate from the legitimate user interface. Additionally, educate users about the risks of clicking on suspicious links and entering credentials on untrusted websites. Implement strict content security policy (CSP) headers to restrict the sources from which the application can load resources.
