Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker to take control of a victim's session by setting a fixed session ID before the victim logs in, which can lead to session hijacking. The attacker needs to know or guess the session ID, and it has been confirmed in specific versions of the PluXml CMS, but other versions may also be at risk.

Technical Description

PluXml CMS allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only versions 5.8.21 and 5.9.0-rc7 were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Related Vulnerabilities

CVE-2026-24351Medium

An attacker with editing privileges on a PluXml CMS website can inject malicious HTML and JavaScript into static pages, which will run whenever someone visits those pages. This means they could steal user data or perform actions on behalf of visitors without their consent.

CVE-2026-24350Medium

This vulnerability allows an attacker to upload a malicious SVG file to a PluXml CMS site, which can then execute harmful code when a victim directly accesses the file. The attacker needs to be authenticated to upload the file, and while the link to the image may not trigger the attack, accessing the file directly will still run the malicious code.
