• CVE-2025-48924: 2.63% estimated exploitation activity in the next 30 days; percentile 85.55 (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.

Uncontrolled Recursion vulnerability in Apache Commons Lang. This issue affects Apache Commons Lang: Starting with commons-lang:commons-lang 2.0 to 2.6, and, from org.apache.commons:commons-lang3 3.0 before 3.18.0. The methods ClassUtils.getClass(...) can throw StackOverflowError on very long inputs. Because an Error is usually not handled by applications and libraries, a StackOverflowError could cause an application to stop. Users are recommended to upgrade to version 3.18.0, which fixes the issue.

# Patch Next advisory brief: CVE-2025-48924

Advisory: Apache Commons Lang is vulnerable to Uncontrolled Recursion when processing long inputs
IDs: CVE-2025-48924, GHSA-j288-q9x7-2f5v
Record: https://patchnext.com/advisories/cve-2025-48924 (revision 1, source checked 26 Oct 2026, 16:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.apache.commons:commons-lang3 3.18.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven commons-lang:commons-lang: affected >= 2.0, <= 2.6
- Maven org.apache.commons:commons-lang3: affected >= 3.0, < 3.18.0; fixed in 3.18.0

## Suggested inspection (read-only)
- Maven commons-lang:commons-lang: check the installed version with your package manager.
- Maven org.apache.commons:commons-lang3: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on commons-lang:commons-lang, org.apache.commons:commons-lang3.
- 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-j288-q9x7-2f5v (GitHub-reviewed advisory GHSA-j288-q9x7-2f5v lists affected ranges: Maven org.apache.commons:commons-lang3 >=3.0 =2.0 <=2.6)

Commands are suggestions: review each one before running it.
