Insecure Temporary File in HuTool

CVE-2023-33695GHSA-7mcw-xmx3-7p8m

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (cn.hutool:hutool-core 5.8.19), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2023-33695

Advisory: Insecure Temporary File in HuTool
IDs: CVE-2023-33695, GHSA-7mcw-xmx3-7p8m
Record: https://patchnext.com/advisories/cve-2023-33695 (revision 1, source checked 26 Oct 2026, 16:17 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: cn.hutool:hutool-core 5.8.19. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven cn.hutool:hutool-core: affected < 5.8.19; fixed in 5.8.19

## Suggested inspection (read-only)
- Maven cn.hutool:hutool-core: 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 cn.hutool:hutool-core.
- 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-7mcw-xmx3-7p8m (GitHub-reviewed advisory GHSA-7mcw-xmx3-7p8m lists affected ranges: Maven cn.hutool:hutool-core >=0 <5.8.19)

Commands are suggestions: review each one before running it.
