Source description

As published by the source; long descriptions are shortened.

Microweber is drag and drop website builder and CMS with E-commerce. The microweber prior 1.2.12 application allows large characters to insert in the input field "post title" which can allow attackers to cause a Denial of Service (DoS) via a crafted HTTP request. The post title input can be limited to 500 characters or max 1000 characters as a workaround.

IDs: CVE-2022-0961, GHSA-hrf4-hcpc-3345
Record: https://patchnext.com/advisories/cve-2022-0961 (revision 1, source checked 26 Oct 2026, 13:59 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 response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist microweber/microweber: affected <= 1.2.11

## Suggested inspection (read-only)
- Packagist microweber/microweber: 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 microweber/microweber.
- Repeat the inspection and confirm that only fixed versions remain installed.

- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
