Summary

CVE-2025-55727 is a critical-severity Eval Injection (CWE-95) vulnerability in Xwiki Pro Macros. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique JavaScript (T1059.007); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and 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.

XWiki Remote Macros, a set of rendering macros for migrating content from Confluence, contains an input sanitization flaw in the column macro. Starting with version 1.0 and prior to 1.26.5, the width parameter is inserted unescaped into generated XWiki syntax, enabling syntax injection. The affected component is the Column.xml macro implementation, which is installed with programming rights in many deployments and therefore exposes the full XWiki execution context.

An attacker who can edit any wiki page or invoke the CKEditor converter can supply a malicious width value. When the macro subsequently renders, the injected syntax executes either as remote code (if the macro was installed by a user holding programming rights) or as Velocity code under the wiki administrator account, resulting in arbitrary code execution on the server.

The project security advisory and the patch released in version 1.26.5 address the issue by properly escaping the width parameter before it is used in XWiki syntax; administrators are advised to upgrade immediately and to audit any custom macros that accept untrusted parameters.

The EPSS score rose from a low baseline to a peak of 0.1908 on 2026-01-13 before receding, indicating that exploitation interest increased after public disclosure.

Vulnerability Data

XWiki Remote Macros provides XWiki rendering macros that are useful when migrating content from Confluence. Starting in version 1.0 and prior to version 1.26.5, missing escaping of the width parameter in the column macro allows remote code execution for any…

more

user who can edit any page or who can access the CKEditor converter. The width parameter is used without escaping in XWiki syntax, thus allowing XWiki syntax injection which enables remote code execution when the macro has been installed by a user with programming right, or it at least allows executing Velocity code as the wiki admin. Version 1.26.5 contains a patch for the issue.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and code analysis can discover eval-injection flaws but does not stop their introduction.

Input validation explicitly requires neutralizing untrusted data before it reaches dynamic evaluation constructs such as eval.

Least privilege limits the damage an injected code fragment can perform once executed.

Secure-development standards and tools can mandate safe coding patterns that avoid unsafe dynamic evaluation.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization and avoidance of unsafe dynamic evaluation.

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

finds

Security testing in development can detect eval injection vulnerabilities before deployment.

prevents

Secure development life cycle mandates input validation and safe coding practices that directly prevent eval injection.

prevents

Application security requirements include rules against dynamic code execution of untrusted input.

prevents

Secure architecture principles discourage unsafe dynamic evaluation constructs.

prevents

Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.

none

Separation of environments limits the blast radius if eval injection occurs in non-production.
