EPSS

• CVE-2023-1932: 0.49% estimated exploitation activity in the next 30 days; percentile 42.37 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.

# Patch Next advisory brief: CVE-2023-1932

Advisory: hibernate-validator Cross-site Scripting vulnerability
IDs: CVE-2023-1932, GHSA-x83m-pf6f-pf9g
Record: https://patchnext.com/advisories/cve-2023-1932 (revision 1, source checked 26 Oct 2026, 16:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.hibernate.validator:hibernate-validator 6.2.0.Final; org.hibernate:hibernate-validator 6.2.0.Final. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.hibernate.validator:hibernate-validator: affected < 6.2.0.Final; fixed in 6.2.0.Final
- Maven org.hibernate:hibernate-validator: affected < 6.2.0.Final; fixed in 6.2.0.Final

## Suggested inspection (read-only)
- Maven org.hibernate.validator:hibernate-validator: check the installed version with your package manager.
- Maven org.hibernate:hibernate-validator: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.hibernate.validator:hibernate-validator, org.hibernate:hibernate-validator.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-x83m-pf6f-pf9g (GitHub-reviewed advisory GHSA-x83m-pf6f-pf9g lists affected ranges: Maven org.hibernate.validator:hibernate-validator >=0 =0 <6.2.0.Final)
