How severe is CVE-2022-42467?

CVE-2022-42467 has a CVSS score of 5.3/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2022-42467?

CVE-2022-42467 affects the following packages: org.apache.isis.core:isis-core (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-42467?

Update org.apache.isis.core:isis-core to 2.0.0-M8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-42467 is resolved across your whole dependency graph.

How do I detect CVE-2022-42467 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.isis.core:isis-core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2022-42467 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2022-42467?

O3 pinpoints whether CVE-2022-42467 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2022-42467 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-42467 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2022-42467?

CVE-2022-42467 has an EPSS (Exploit Prediction Scoring System) score of 1.2%, placing it in the 64th 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.

When was CVE-2022-42467 published, and has it been updated?

CVE-2022-42467 was published on October 19, 2022 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

When running in prototype mode, the h2 webconsole module (accessible from the Prototype menu) is automatically made available with the ability to directly query the database. It was felt that it is safer to require the developer to explicitly enable this capability. As of 2.0.0-M8, this can now be done using the 'isis.prototyping.h2-console.web-allow-remote-access' configuration property; the web console will be unavailable without setting this configuration. As an additional safeguard, the new 'isis.prototyping.h2-console.generate-random-web-admin-password' configuration parameter (enabled by default) requires that the administrator use a randomly generated password to use the console. The password is printed to the log, as "webAdminPass: xxx" (where "xxx") is the password. To revert to the original behaviour, the administrator would therefore need to set these configuration parameter: isis.prototyping.h2-console.web-allow-remote-access=true isis.prototyping.h2-console.generate-random-web-admin-password=false Note also that the h2 webconsole is never available in production mode, so these safeguards are only to ensure that the webconsole is secured by default also in prototype mode.
