Which packages are affected by CVE-2023-26476?

CVE-2023-26476 affects the following packages: org.xwiki.platform:xwiki-platform-livetable-ui (Maven), org.xwiki.platform:xwiki-platform-wiki-ui-mainwiki (Maven), org.xwiki.platform:xwiki-platform-livetable-ui (Maven), org.xwiki.platform:xwiki-platform-wiki-ui-mainwiki (Maven), org.xwiki.platform:xwiki-platform-livetable-ui (Maven), org.xwiki.platform:xwiki-platform-wiki-ui-mainwiki (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-26476?

Update org.xwiki.platform:xwiki-platform-livetable-ui to 13.4.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-26476 is resolved across your whole dependency graph.

How do I detect CVE-2023-26476 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-livetable-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-26476 if there is no patch (or I can't update yet)?

Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Is CVE-2023-26476 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-26476, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-26476?

CVE-2023-26476 has an EPSS (Exploit Prediction Scoring System) score of 2.2%, placing it in the 83th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-26476?

CVE-2023-26476 is classified as Information Exposure (CWE-200), CWE-307 (CWE-307). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2023-26476 published, and has it been updated?

CVE-2023-26476 was published on March 2, 2023 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-livetable-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

Update org.xwiki.platform:xwiki-platform-livetable-ui to 13.4.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-26476 is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
