Emlog is an open-source website building system. In version 2.5.23, article creation functionality is vulnerable to cross-site request forgery (CSRF). This vulnerability allows an attacker to force a user to post an article with arbitrary, attacker-controlled content. When combined with stored cross-site scripting, it can lead to account takeover. As of the time of publication, no known patched versions are available.
The severity of this vulnerability is classified as high, with a CVSS score of 7. This level of severity indicates a significant risk to organizations using the affected version of Emlog. Organizations should prioritize patching immediately to mitigate the potential impact.
Risk to organizations includes unauthorized posting of content and potential complete account takeover. Attackers may leverage this vulnerability to manipulate users and gain control over their accounts, leading to further exploitation of the site.
Currently, there are no known exploits available for this vulnerability. However, given its nature, organizations should remain vigilant and monitor for any signs of exploitation. Organizations should address this vulnerability in their priority patch cycle.
Vulnerability Details
The vulnerability is classified under the Common Weakness Enumeration (CWE) IDs CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) and CWE-352 (Cross-Site Request Forgery (CSRF)). This combination presents a critical risk to the integrity of user accounts.
The CVSS score of 7 indicates that the attack vector is network-based and the attack complexity is low. No privileges are required for exploitation, and user interaction is passive.
The affected product is Emlog, specifically version 2.5.23. The vulnerability was published on January 2, 2026, and the status is currently analyzed.
Technical Analysis
The vulnerability occurs due to improper validation of requests made by the user. An attacker can exploit this by crafting a malicious request that is accepted by the server without proper authentication checks.
This attack can be executed remotely, allowing attackers to initiate CSRF attacks over the network. The attack complexity is low, meaning that minimal skill is required to execute an attack against a vulnerable system.
No privileges are required to exploit this vulnerability, which increases its potential impact. User interaction is passive, meaning that victims may be unaware that an attack is taking place.
The integrity of the system is at high risk, as attackers can manipulate content posted on behalf of legitimate users, leading to account takeovers and further exploitation.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability is significant. Organizations utilizing Emlog version 2.5.23 are at risk of unauthorized content manipulation, which can severely damage their reputation and user trust.
The potential blast radius is extensive, as the vulnerability can affect all users of the system. This makes the urgency assessment high, given the CVSS score of 7. Organizations should prioritize patching immediately to prevent exploitation.

Affected Versions
The affected version for this vulnerability is Emlog 2.5.23. If version information is missing, note that all versions prior to the vendor patch are affected.
Mitigation & Remediation
Organizations should monitor for updates from Emlog regarding patched versions. It is crucial to apply updates as soon as they become available. If a patch is not available, organizations should consider implementing workarounds, such as disabling the article creation functionality until a fix is released.
Configuration hardening can also help mitigate the risk of exploitation. Network controls should be established to limit interactions from untrusted sources.
Organizations should validate remediation through penetration testing to identify similar weaknesses.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized content postings and any unusual user behavior that may suggest account takeovers.
Behavioral anomalies, such as changes in posting frequency or content patterns, should be flagged for further investigation.
