Summary This vulnerability is a patch bypass that exploits catastrophic backtracking in a regular expression used to filter ATTACH statements in AdminNeo's SQLite functionality. The original vulnerability (CVE-2021-43008) allowed authenticated users to create PHP files through SQLite ATTACH statements, achieving remote code execution. The patch introduced a regex filter to block ATTACH queries, but this filter is vulnerable to catastrophic backtracking.

# Patch Next advisory brief: CVE-2026-96634

Advisory: AdminNeo SQLite: multi_query Incorrect Check of Function Return Value RCE
IDs: CVE-2026-96634, GHSA-p96f-p2p2-2g3h
Record: https://patchnext.com/advisories/cve-2026-96634 (revision 2, source checked 31 Oct 2026, 06:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: adminneo-org/adminneo 5.5.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist adminneo-org/adminneo: affected < 5.5.1; fixed in 5.5.1

## Suggested inspection (read-only)
- Packagist adminneo-org/adminneo: 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 adminneo-org/adminneo.
- 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.
