CVE-2026-33229: CWE-862: Missing Authorization in xwiki xwiki-platform
CVE-2026-33229 is a high-severity vulnerability in the XWiki Platform prior to versions 17. 4. 8 and 17. 10. 1. It involves missing authorization in the scripting API, allowing users with script rights to bypass sandbox restrictions in the Velocity scripting API and execute arbitrary Python scripts. This can lead to full compromise of the XWiki instance's confidentiality, integrity, and availability. The vulnerability is fixed in versions 17. 4. 8 and 17.
AI Analysis
Technical Summary
The vulnerability CVE-2026-33229 affects XWiki Platform versions from 17.0.0-rc-1 up to but not including 17.4.8, and from 17.5.0-rc-1 up to but not including 17.10.1. It is caused by missing authorization checks in the scripting API, specifically allowing users with script rights to bypass the sandboxing of the Velocity scripting API. This enables execution of arbitrary Python scripts, resulting in full access to the XWiki instance. The issue is addressed by official fixes in versions 17.4.8 and 17.10.1. The CVSS 4.0 score is 8.6 (high), reflecting network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows any user with script rights to execute arbitrary Python code on the XWiki instance, leading to complete compromise of the platform's confidentiality, integrity, and availability. This can result in unauthorized data access, data modification, or service disruption. However, exploitation requires the attacker to already have script rights, which is a high privilege level.
Mitigation Recommendations
This vulnerability is fixed in XWiki Platform versions 17.4.8 and 17.10.1. Users should upgrade to one of these versions or later to remediate the issue. Since the vulnerability requires script rights, it is also recommended to restrict granting script rights to only fully trusted users. Patch status is not explicitly stated beyond the fixed versions; therefore, verify with the vendor advisory for the latest remediation guidance.
