CVE-2026-55525: Mervinpraison Praisonai

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the web_crawl function validates only the initial URL before _crawl_with_httpx uses httpx.Client(follow_redirects=True). Redirect targets are not revalidated, so an attacker who influences a crawl target can redirect a public URL to loopback, private network, or cloud metadata services while ALLOW_LOCAL_CRAWL remains disabled. The fetched internal response is returned to the agent context. This issue is fixed in version 1.6.58.

Affected products

• Mervinpraison Praisonai: before 4.6.58 (fixed in 4.6.58)
• Mervinpraison Praisonaiagents: before 1.6.58 (fixed in 1.6.58)
