Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for microweber/microweber, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of microweber/microweber for GHSA-hrf4-hcpc-3345. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
