What is CVE-2026-23795?

CVE-2026-23795 is a medium-severity XML external entity injection (XXE) vulnerability in org.apache.syncope.client.idrepo:syncope-client-idrepo-console (maven), affecting versions >= 3.0.0, < 3.0.16. It is fixed in 3.0.16, 4.0.4. An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs.

How severe is CVE-2026-23795?

CVE-2026-23795 has a CVSS score of 4.9 (Medium). 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.

Is there a fix for CVE-2026-23795?

Yes. CVE-2026-23795 is fixed in 3.0.16, 4.0.4. Upgrade to this version or later.

Is CVE-2026-23795 exploitable, and should I be worried?

Whether CVE-2026-23795 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.

What actually determines whether CVE-2026-23795 is exploitable, and how bad it is?

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.

Q: How do I fix CVE-2026-23795?

Upgrade: org.apache.syncope.client.idrepo:syncope-client-idrepo-console to 3.0.16 or later, org.apache.syncope.client.idrepo:syncope-client-idrepo-console to 4.0.4 or later.

Summary

Improper Restriction of XML External Entity Reference vulnerability in Apache Syncope Console. An administrator with adequate entitlements to create or edit Keymaster parameters via Console can construct malicious XML text to launch an XXE attack, thereby causing sensitive data leakage occurs.

This issue affects Apache Syncope: from 3.0 through 3.0.15, from 4.0 through 4.0.3.

Users are recommended to upgrade to version 3.0.16 / 4.0.4, which fix this issue.

Impact

An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs. Typical impact: local file disclosure, server-side request forgery, or denial of service.

CVE-2026-23795 has a CVSS score of 4.9 (Medium). The vector is network-reachable, high 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 (3.0.16, 4.0.4); upgrading removes the vulnerable code path.

Affected versions

org.apache.syncope.client.idrepo:syncope-client-idrepo-console (>= 3.0.0, < 3.0.16) org.apache.syncope.client.idrepo:syncope-client-idrepo-console (>= 4.0.0, < 4.0.4)

Security releases

org.apache.syncope.client.idrepo:syncope-client-idrepo-console → 3.0.16 (maven) org.apache.syncope.client.idrepo:syncope-client-idrepo-console → 4.0.4 (maven)

Kodem intelligence

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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
