CVE-2026-44179 is a critical-severity security vulnerability in com.xwiki.pro:xwiki-pro-macros (maven), affecting versions >= 1.13, < 1.14.5. It is fixed in 1.14.5.
Summary The excerpt-include macro does not properly escape the title of the included page and executes the content of the excerpt with the macro's rights. Therefore, it is vulnerable to XWiki syntax injection via the included page's title and content, allowing remote code execution for any user who can edit a page. Details The title of the included page isn't escaped in ExcerptInclude.xml#L277. Further, the content of the excerpt macro is rendered to XWiki syntax and output into the macro's content such that it is executed with the macro's rights. PoC As a user without script or programming right, create a page named Exploit. In the edit screen, change the title to {{async}}{{groovy}}println("Hello from Groovy Title!"){{/groovy}}{{/async}}. Set the content to Save and view the page. If this displays "Hello from Groovy Title!" without the surrounding macro code or "Hello from Groovy content!", the attack succeeded. Impact Remote code execution impacts the confidentiality, integrity and availability of the whole XWiki installation.
CVE-2026-44179 has a CVSS score of 9.9 (Critical). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (1.14.5). Upgrading removes the vulnerable code path.

com.xwiki.pro:xwiki-pro-macros (>= 1.13, < 1.14.5)com.xwiki.pro:xwiki-pro-macros → 1.14.5 (maven)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

CVE-2026-44179 is a critical-severity security vulnerability in com.xwiki.pro:xwiki-pro-macros (maven), affecting versions >= 1.13, < 1.14.5. It is fixed in 1.14.5.
CVE-2026-44179 has a CVSS score of 9.9 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
com.xwiki.pro:xwiki-pro-macros (maven) versions >= 1.13, < 1.14.5 is affected.
Yes. CVE-2026-44179 is fixed in 1.14.5. Upgrade to this version or later.
Whether CVE-2026-44179 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
Upgrade com.xwiki.pro:xwiki-pro-macros to 1.14.5 or later.
