Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2024-42489 is a critical-severity Injection (CWE-74) vulnerability in Xwiki Pro Macros. Its CVSS base score is 10.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 38% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-42489 is a remote code execution vulnerability in the Pro Macros extension for XWiki, which supplies Confluence-compatible rendering macros. The root cause is missing output escaping in the Viewpdf macro (and similarly in Viewppt and related macros), specifically within the handling of user-supplied content passed to the CKEditor.HTMLConverter page. The flaw is tracked as CWE-74 and carries a CVSS 3.1 score of 10.0.
Any unauthenticated or low-privileged user who can view the CKEditor.HTMLConverter page, or who holds edit or comment rights on any page, can supply crafted input that results in arbitrary code execution on the server. The attack requires no user interaction and can be performed over the network.
The vulnerability is fixed in Pro Macros version 1.10.1. The project security advisory and the associated commit on GitHub document the addition of proper escaping at the affected template locations in Viewpdf.xml and related files.
The EPSS score reached 0.4540 at disclosure and has remained at that level without further increase.

Security testing in development catches injection vulnerabilities before release.
Logging supports detection of injection attempts but does not prevent the weakness.
Monitoring activities can identify active injection attacks after they occur.
Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.
Application security requirements explicitly call for controls against injection attacks in software design.
Secure architecture principles reduce injection surfaces but do not prescribe specific neutralization techniques.
