• CVE-2022-1631: 8.85% estimated exploitation activity in the next 30 days; percentile 95.21 (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.

Users Account Pre-Takeover or Users Account Takeover. in GitHub repository microweber/microweber prior to 1.2.15. Victim Account Take Over. Since, there is no email confirmation, an attacker can easily create an account in the application using the Victim’s Email. This allows an attacker to gain pre-authentication to the victim’s account. Further, due to the lack of proper validation of email coming from Social Login and failing to check if an account already exists, the victim will not identify if an account is already existing. Hence, the attacker’s persistence will remain. An attacker would be able to see all the activities performed by the victim user impacting the confidentiality and attempt to modify/corrupt the data impacting the integrity and availability factor. This attack becomes more interesting when an attacker can register an account from an employee’s email address. Assuming the organization uses G-Suite, it is much more impactful to hijack into an employee’s account.

# Patch Next advisory brief: CVE-2022-1631

Advisory: Incorrect Authorization in microweber
IDs: CVE-2022-1631, GHSA-73rp-q4rx-5grc
Record: https://patchnext.com/advisories/cve-2022-1631 (revision 1, source checked 26 Oct 2026, 14:01 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: microweber/microweber 1.2.15. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist microweber/microweber: affected < 1.2.15; fixed in 1.2.15

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